Background
• China’s first car was made in 1956 and the
first private car was made in early 1980;
• In 1994, the government started to
encourage people to buy private cars;
• Nowadays the car ownership in China has
reached 290 million With the growth of
27.5 million cars and 33.1 million drivers in
2016 (Xinhua news agency 2017);
• Traffic congestion and environment
problems have been more serious;
• More traffic policies are carried out to
restrict the amount of cars since 2008;

The proposed scope
• Taking Beijing ,Shanghai ,Tianjin,
Guangzhou and Hangzhou as the examples;
• The time series are divided into three parts:
“1985 - 2008”, “2008 - 2015”, “2015 -
2030”;
• Choose GDP per capita (RMB), population
data (1,000 people) and fuel price (RMB)
as the main valuable factors.
The proposed methodology
• Econometric model:
ln 𝐶𝑡 = 𝐾 +
𝑖=1
𝑚
𝛼𝑖 ln 𝐶𝑡−𝑖 +
𝑗=0
𝑛
𝛽𝑗 ln 𝐺𝐷𝑃𝑡−𝑗
+ 𝑘=0
𝑜
𝛾 𝑘 ln 𝑃𝑡−𝑘 𝑙=0
𝑝
δ𝑙 ln 𝐹𝑡−𝑙 + 𝜀𝑡;
• For the eq., C is the number of vehicles,
GDP is real GDP per capita ,P is population
and F is fuel price, 𝜀𝑡 is the error of the
econometric model, m n o p will be
chosen to fit the error 𝜀𝑡 and α, β, γ, δ, k
are the estimated parameters;
• Intervention analysis will be used in time
series econometrics to estimate the impact
of traffic polices.
Expected conclusions
• GDP per capita and population could be the
main variables of the car ownership model;
• After carrying out traffic policies,
comparing with the actual data, the growth
of the car ownership starts to slow down;
• The growth of the predictive results should
be more slowly.
Aims and Objectives
• By analysing the previous car ownership
data from to get estimated results;
• To find the differences between the actual
data and estimated results;
• Whether the traffic policies have positive
impacts on the restraint of car numbers?
• What is the predicted value of car ownership
in the future (2030)?

2. Experimenter Effect and Demand Characteristics in Driving Simulator Trails
The Impact of Experimenter Presence and instructions on Participants’ Behaviour
By Abdulhamid Alfalah MSc. Sustainability in Transport Supervised by: Dr. Daryl Hibberd 2nd Reader: Dr. Ruth Madigan
In a study by Parameswaran (2003), school children
in USA and India were given a task to draw a map
of the school’s neighbourhood, in the first study no
instructions on the type of map were given. In the
second study, participants were split into 2 groups,
both groups had instructions on a different type of
map required. This resulted in a change in
performance in terms of “cognitive maturity”
compared to first study.
Background
Experimenter effect (Experimenter bias),
is the experimenter caused bias on the
results of an experiment
Demand characteristics, are
the features in experimental
condition that may induce or
result in certain behaviours from
participants that can affect the
results of the experiment
To study the effect of demand characteristics
conditions in driving simulator trials by studying the
effect of experimenter’s presence during the trial, and
the effect of different set of instructions on the
behaviour of participants.
Objective
Methodology
The study will take place at the University of Leeds low fidelity driving
simulator. The participants will be divided into four groups, each
group will have to perform the driving task twice
•Trial 1: EP/Min
•Trial 2: EP/MaxGrp1 "EP"
•Trial 1: NP/Min
•Trial 2: NP/MaxGrp2 "NP"
•Trial 1: Min/NP
•Trial 2: Min/EP
Grp3
"Min"
•Trial 1: Max/NP
•Trial 2: Max/EP
Grp4
"Max"
Instructions Conditions:
Minimum instructions(Min), participants will be given general
instructions on how to use the simulator, and to stay on a certain lane
during the task (until the conditions of the task demand otherwise).
Maximum instructions (Max), participants will be given detailed
instructions explaining what variables will be measured from their task
(i.e. speed, and overtaking behaviour).
“Experimenter Presence” conditions:
Experimenter present (EP): Experimenter will remain in the same room
observing the participants during the task
Experimenter NOT present (NP): Experimenter will participants alone
during the task
Observed Parameters During
Task:
Speed: variation of Mean, Max,
and Min Speed.
Overtaking Behaviour: no of
overtaking manoeuvres
Nichols and Maner (2008) studied the effect of
the participants’ previous knowledge of the
experiments hypothesis. Participants were told by
a confederate a “hypothesis” of the study they
are about to participate in. the study found that
participants in general tend to behave in way that
confirm that hypothesis. Factors like attitudes
towards the experiment/ experimenter, social
desirability influenced participants’ behaviour.
As for transport, little research has been done in this
area. A study by Harvey and Burnet (2016) to
examine the effect of incentives and instructions on
the feeling of “presence” (the extent to which they
believed they were actually driving and not in a
simulated environment), the study found no
significant impact on the participants’ feeling of
“presence”, however, incentives are found to induce
a lower mean speed. The study focused more on
“ecological validity” aspect, it didn’t examine the
impact of instructions or other demand
characteristics on participants’ behaviour in driving
trails.
Cues that

Limitations:
Possible limitations to proposed approach can be
the study of the effect experimenters’ expectations
by comparing results of different experimenters.
Future Implications:
Findings in this research may result in new factors (instructions and other
experimenter cues) to be considered in experimental design of simulator trials to
eliminate any influence on participants’ behaviour, as well as future research
possibilities for additional demand characteristics
3. LOW-COST DRIVING SIMULATION, UNDERSTANDING TRANSITION OUT OF AUTOMATED DRIVING BY
USING DESKTOP SIMULATOR
Author: Agung Adri Laksono – MSc Transport Planning Supervisor: Gustav Markkula
BACKGROUND STUDY
60%
Human behaviour is the
most factor that causes road
accident (Rosolino et al.
(2013)
Autonomous vehicles can
generate the reduction on road
traffic accident - prevent and
reduce failure on human factor
(Bertoncello and Wee, 2015).
However, during the automation, the driver’s attention
may shift away and potentially impairs driver’s ability
Running desktop simulator
can be useful to address
these problems by studying
several aspect such as the
Reaction Time and
Visual Angle.
Therefore, this research will investigate the reaction
time and visual angle during the automation. Also this
research will refer to Louw et al., (2017) that has used
driving simulator to generate comparative result.
To what extent the generated result
of experimental reseach on
transition out such as reaction time
and visual angle in desktop
simulator compared to the driving
simulator ?
RESEARCH QUESTION
Aim :
Obtain the comparative result between desktop simulator
and previous study which used driving simulator in term of
investigating the reaction time and visual angle during the
transition out.

4. Assessing Diverging Diamond Interchange against
Traditional Signalized Roundabout
MSc (Eng) Transport Planning and Engineering
BACKGROUND
NAME: AHMED ABDELBAKI 2016/17 SUPERVISOR: JEREMY THOMPSON
• Roundabout is one of the most effective junction
types as it “minimize delay for vehicles whilst
maintaining the safe passage of all road users
through the junction”, especially when arm flows
are reasonably balanced.
• When demand exceeds the roundabout capacity,
critical queues, unbalanced delays and lower safety
level will result. The problem becomes more
critical when queues built up and reach the main
road on the interchange, even when converting to
signal control .
• In order to avoid problems on roundabouts and
conventional diamond interchanges, an alternative
has been introduced in the USA. Diverging
Diamond Interchange (DDI) have become a popular
choice since 2009.
• DDI manages higher traffic volumes and improves
safety, performance and cost effective.
• DDI has less conflict points (14) than conventional
diamonds (26) and more conflict points than a
signalised roundabout (12). While, signalized
roundabouts require 4 separate signal junctions,
the DDI requires only 2, thus reducing delays
through the interchange.
• DDI is more beneficial for cyclist and pedestrian,
improving safety reducing conflicts for these users.
• DDIs are operational in 86 intersections in the USA,
3 in France and 1 in UAE, and 1 in Denmark, non in
England

OBJECTIVES
PROPOSED METHODOLOGY
WHAT IS DDI?
• Vehicles are switched to go in the opposite
direction of the carriageway on the intersection,
and return back after the intersection.
• The interchange manages higher traffic volumes,
due to the shorter staging arrangement. On DDI
interchanges the right turn into the slip road are
unopposed.

The main objective of the study is to analyze the optimal
places and type of infrastructure (roads mainly) to invest in
trying to improve the connectivity in rural areas of Ghana
to make health facilities more accessible for citizens.
There will be two ranges to take into account:
- The national infrastructure
- The rural roads available (focusing on these ones)
Connect both of them without creating isolated networks
not integrated into the bigger picture scheme is essential in
order to be able to keep expanding the system in the future.
With the literature studied and the data obtained online
through different organisations, plot and study the information
using the software QGIS.
Steps to follow:
− Literature and background study: Infrastructure and health
problems.
− Critical analysis of the existing network
Consider: Topography and climate, Politics and economy,
Social situation, Health system, Road sector in Ghana,

6. •For almost over 30 years in Hong Kong, bus networks have
not seen major changes nor innovations. However during
this time, 1) people and activities could have changed, 2)
roads have become more congested and 3)new MTR
railways have ‘caught-up’ and an efficient and reliable
substitute has been available.
•These changes imply bus amendments are necessary but
to date, they have been difficult to conduct - This is
because there is a part or section of each bus route which
is still more point-to-point and direct compared to using
MTR. Also, the Public housing estates which are usually not
well-served by the railways but requires affordable
transport means that buses are also important for meeting
equity needs. All in all, with lots of objections to proposed
amendments, oversupply of services is resulted.
•It is thus important to ‘rationalize’ transport services by
removing wasteful competition to maintain economic
efficiency. This study looks, from the basis of passenger
and operator welfare-maximization, the extent that rail
‘substituting’ buses is desirable.
Background – The ‘problem’
•To conduct bus patronage counts, generalized cost
calculations and interviews with passengers on the
existing bus services
•To form a theoretical model to explain the factors that
affect the travel mode choices at different times of day
and at different sections of the same corridor
•To find out if efficiency can be achieved with equity
•To inform and recommend to the policy over the most
economic welfare-maximizing competition and/or
coordination levels based on the results
Aims and Objectives
Keen intermodal competition in Hong Kong –
Should bus and rail compete with each other or coordinate?
Student: Alex Fung - Msc Transport Economics (2016/17) - Supervised by Dr Tony Whiteing & Dr Andrew Tomlinson
On 2 representative HK
corridors, design a (simplified)
O-D trip-matrix based on actual
commuting practices;
Using Census data to assist
identifying O-D pairs
Identify the common
travel alternatives of
these O-D pairs,
calculate and compare
the generalized costs of
using each
Also conducting interviews and bus
patronage counts, recording
passenger opinions (e.g. mode
attributes) to help understand the
generalized cost difference and to
reflect the welfare impacts on
operator’s costs when alternative
bus strategies are proposed
Present the factors affecting generalized
cost using a theoretical model,
Highlight the factors that are of more
significant impact to assist policy
recommendations
MTR overcrowding
Comfortable
seats on buses
Methodology and Data sources
•In general, the mode a lower generalized cost of using
implies higher accessibility levels and higher welfare
levels enjoyed, for that O-D pair.
•It is expected that this study shall respond to the issue
of having multi-purpose bus routes that vary in
patronage at different sections of the route at different
times of day, on what is the social-welfare maximizing
competition and/or coordination level for ‘rationalizing’
oversupply of services.
•It is believed that the factors outlined in the theoretical
model is beneficial for future research in terms of ways
to model the relative mode attractiveness on the 2 core
urban modes, bus and rail
•Policy recommendations of alternative bus strategies:
These include long route splitting, limited-stopping
arrangement, merging/shortening redundant route
sections etc.

7. Understanding Pedestrian Interactions with Automated Vehicles
OBJECTIVES
To achieve this aim, the following objectives have been
set:
Understanding pedestrian interactions with the
non-automated vehicles
Studying different aspects of this understanding,
such as the cultural differences that have a crucial
role in this interrelationship
Finally, understanding of the factors that affect
pedestrian interactions with AVs
METHODOLOGY & DATA
COLLECTION
Literature Review of studies
regarding the driver-pedestrian
interactions, as well as some
recent studies regarding the
interaction between pedestrians
and AVs.
Data Collection by focus groups
interviews (2-3 with 5-8 people
each). The groups consist of
participants of different genders and
nationalities, with cultural differences
who are asked to state their preferred
choices across a set of different
scenarios.
Data collection by
questionnaires. They include
questions regarding the pedestrians-
drivers interactions and some others
regarding some important aspects of
the pedestrians – AVs interactions,
based on the outcomes of the focus
groups discussions.
Analysis of the results. Qualitative
analysis of the focus groups outputs by
recording them and taking notes, and
statistical analysis of the
questionnaires’ results by using the
statistical software SPSS.
AIM
The aim of this project is to understand the
interactions between the pedestrians and
the drivers of the non - automated vehicles
and identify how these interactions may
change when introducing automated driving
(SAE Level 4 AVs).
INTRODUCTION - BACKGROUND
Even though there is some understanding of how pedestrians
interpret the actions of vehicles with drivers, there are great
challenges for interpreting these communication strategies in the
case that the driver is absent or is not maneuvering the vehicle
(Merat et al., 2016).
People of different gender, nationalities and with cultural
differences perceive the pedestrian - vehicle interactions in a
different way.
Pedestrians’ safety might decrease when driver’s role changes
from active to passive (Lagstrom and Lundgren, 2015).
Pedestrians perceive this new driver behavior as hazardous when
they are unaware that the vehicle is driving in the automated
mode (Lagstrom and Lundgren, 2015).
Hence, pedestrians need to be provided with additional feedback
in the interaction with the automated vehicles (AVs) due to the
inadequate information.

Utilization of Aircraft Classification Number and Pavement Classification Number
(ACN-PCN) as part of Airport Pavement Management System (APMS)
Study Case: Soekarno-Hatta International Airport (SHIA), Jakarta, Indonesia
Background
ACN-PCN is a method to describe the relationship
between the airfield pavement strength and the
aircraft. ACN is published by aircraft manufacturers
and PCN is issued by the airport's operator. The
purpose is to determine whether an aircraft can use
an airfield pavement.
Four methods of ACN-PCN recognized by
International Civil Aviation Organization (ICAO):
1. Classic method (CBR method)
2. Graphical method (by UK Dept. of Defence)
3. Federal Aviation Administration (FAA) standard
method
4. Field test by Heavy-Weight-Deflectometer
Expected Findings
1. The method(s) that is preferred to use in
evaluating the airport’s PCN value in Indonesia
and the reasons
2. The residual life of the existing pavement
Objectives
1. To assess which method is preferred by the
operator(s) as part of the APMS.
2. To discuss the advantages and the drawbacks in
implementing the methods.
3. To evaluate the ACN-PCN of SHIA, Jakarta
PCN Reporting Format Ex.: PCN 50/F/B/X/U
1. Numerical PCN Value, an index of the pavement
capacity loads regarding of a standard single
wheel load at a tyre pressure of 1.25 MPa.
2. Pavement Type: F for flexible and R for rigid.
3. Subgrade Strength Category: A, B, C or D.
4. Allowable Tyre Pressure: X, W, Y or Z.
5. Evaluation Methodology: U for usage and T for
technical analysis.

9. Introduction
Connectivity throughout road networks is an issue of major interest for local and national
governments, it is considered as an index of productivity and development. For that
reason, studies have been developed to provide a solid framework that helps poli-
cymakers to achieve the highest benefit of their decisions. Regardless the deci-
sions made, networks may occasionally undergo reductions of their designed
capacity due to unexpected and undesirable events such as accidents or nat-
ural disasters like earthquakes and flooding. Then, with limited resources
for reconstruction and enhancement, policymakers must decide how to
distribute the official budget to minimize the impact of possible disrup-
tions.
Objectives
Formulate the Network Investment Allocation Problem as Mathe-
matical Problem with Equilibrium Constrain.
Propose a solution using a Simulating Annealing Approach.
Test different scenarios and evaluate the solution using at least two net-
work examples.
Evaluate the performance of the methodology in real scale networks.
Theoretical Framework
Network Investment Allocation Problem
The Network Design Problem (NDP) is formulated to identify the combination of links (i.e. road, streets), whose availability
(construction) or capacity expansion, maximize the network benefit (or minimize costs) in order to meet the growing trip demand and
prevent congestion (Wang, et al., 2014). Authors subdivide NDP into three categories: Continues Network Design Problems (CNDP),
Discrete Network Design Problem (DNDP) and the mixed version (MNDP) (Wang, et al., 2014). The first category suggests to add new
links to the network, while the second one aims to increase the existing capacity and the third one is a combination of the first two. In
this dissertation it will be formulated the Network Investment Allocation Problem (NIAP). This problem consists on identifying what
is the best invest, to recover capacity after disruption or to increase capacity on other non-disrupted links.
Simulated Annealing
In condensed matter physics, the simulation of the annealing of solids is a process which objective is to minimize the energy between
particles by arranging them aleatory. To achieve the minimal energy the solid is exposed to heat until it melts (maximum heat), then it
is cooled up slowly until it turns into solid state again (cooling scheme). As analogy of this process, Kirkpatrick (1983) developed an
algorithm to solve combinatorial problems, that consists of four elements: a representation of the system, a random generator of per-
turbances, an objective function and the annealing schedule (maximum temperature and cooling scheme).
Methodology
It will be proposed an algorithm to solve the NIAP, which will be first tested using an small network. Once the solution is proved to
work, the performance of the algorithm will be evaluated using a real scale network.
Algorithm

Create perturbance function: Select randomly the set of links where the investment

tures and cooling schemes will be logged.

paths, etc.) and outputs (flow, new capacities, system cost).

networks.

Will the forthcoming Trafford Park Metrolink line bring about a car-to-tram modal shift for Trafford Centre
visitors? An investigation.
Literature Review
o Passengers in light rail corridors tend to shift from bus rather
than cars (Lee and Senior, 2013).
o Light rail has the potential to reduce the rate of increase of
highway traffic levels (Bhattachanjee and Goetz, 2012).
o Metrolink attracted more passengers than initially forecast
when first opened (Knowles, 1996).
o Metrolink mainly took mode share from buses when first
opened (Senior, 2009).
o TfGM is attempting to reduce motorised transport and
promote sustainable transport (TfGM, 2017).
Background
o Trafford Park line to Trafford Centre on Manchester’s
Metrolink announced in October 2016.
o Reducing car dependency was one of the motivating factors as
part of Greater Manchester’s ‘2040 Strategy’ (TfGM, 2017).
o The Trafford Centre is an attractive place for car users due to:
• Location by the M60
• 11,500 free carparking spaces
• ANPR security measures
o So, to what extent will Trafford Centre car users switch to
using the tram to access the centre? This dissertation will
critique this aspect of the scheme.
Aim
o To evaluate whether more could be done to encourage car-to-tram
modal shift for the Trafford Park line and future schemes.
Objectives
o 1) To establish an understanding of the projections that have been made
by the relevant authorities.
o 2) To understand the attitudes and behaviours of current car users at the
Trafford Centre.
o 3) To use previous case studies, literature and primary research to make
an overall evaluation of the extent to which a modal shift will occur.
Scope
o I intend to conduct my questionnaire to a point where I have a
substantial and representative sample of car users at the Trafford
Centre.
o I believe interviews and secondary research will also garner reliable
data, as this will provide information that has already been collected
with the resources of large organisations.
Anticipated Conclusions
o Preliminary research (interview with TfGM engineer) suggests that
TfGM and associated stakeholders could do more to encourage car
users to switch to the Metrolink line once it opens.
o Questionnaires collected at the Trafford Centre should assist with
making this conclusion.
o I intend to provide recommendations for the extent to which TFGM
and future scheme planners should take action to encourage this
modal shift.

Preliminary Results
o I have already undertaken some preliminary research in the form of a
semi-structured interview with a Business Case Developer for the
Trafford Park Line and a study of grey literature:
• 90% public support for the scheme.
• TfGM wants to create a ‘viable alternative’ for car users, but
whether car users will switch modes remains unclear.
• The focus seems to be on bus users and those without access to a
car.
o These results will inform the questions that I ask in my questionnaire.

11. Evaluating transport governance structures for Metro
Manila using cases on mass transit programmes
Anne Patricia E. Mariano, ts16apem@leeds.ac.uk Supervisor: Dr. Katharine Pangbourne
Second Reader: Professor Greg MarsdenMSc Sustainability in Transport
Potential Cases: Mass Transit Programmes
1. Limited-stop bus services were introduced in 2015 to encourage bus ridership.
These services successfully reduced travel ?me but do not replace exis?ng routes.
2. Studies were conducted in 2014 and 2016 to (a) iden?fy required mass transit
routes by reviewing demand and exis?ng services, and (b) present op?misa?on
plans for 3 routes. These are yet to be implemented in favour of further studies.
3. Infrastructure projects such as a bus rapid transit system between 2 ci?es and a
commuter rail to connect 4 regions were posi?vely received by stakeholders albeit
with concerns on the poli?cal costs of land acquisi?on.
Mode Share of Metro Manila Trips
Based on household interview surveys and a total of 35.5 million trips (JICA, 2014)
Transportation Issues
• Total metro rail lines of only 50km (DOTr, 2015)
• Transit primarily informal, lacking organised
stops, schedules, and services (DOTr, 2015)
• 18% increase in travel 9me on buses from
1996 to 2014 (JICA, 2015)
• Over 2M registered vehicles and some of the
worst conges?on in the world (DOTr, 2015; Waze,
2015)

12. Data Fusion: A Simulation Approach
Aseem Awad
Institute for Transport Studies, Leeds
Objectives
We explore ways of addressing the issue of Verac-
ity and Value in Big Data.
• Apply techniques of Data Fusion to create a
Origin-Destination with high fitness-for-use, to
provide benchmark for the performance of our
models.
• Create Geospatial Microsimulation to visualize
results of the transport model based on our
datasets. Focus on one system.
• Use the hybrid Geospatial Microsimulation to
iteratively improve a simulation model of the
urban system. Compare the results with
analytical approaches.
Introduction
Transport modelling can be conceptualised as mod-
elling of transport demand, transport supply and the
evolving interaction of these two factors. In this dis-
sertation we set out to create and exhibit a demand
model with high fitness-for-use by utilising Data Fu-
sion and an innovative hybrid of Spatial Microsimu-
lation and Agent-Based simulation.
Figure 1: Agent-Based model to simulate changes in the built
environment of East Anglia
Materials
The following materials are required to complete the
research:
• A social media dataset coming from active
individuals. (STRAVA)
• Data of Automatic Traffic Detection readings.
• Data regarding Land-Use and demographics.
• A software suitable for Agent-Based Simulation.
Previous attempts in this direction have been
made using MATsim-T and NetLogo. We intend
to use R and NetLogo.
Methodology
• We apply the ITS Data Fusion techniques
described in [1] to STRAVA and other
demographic datasets.
• We use Geospatial Microsimulation for a separate
process of Data Fusion.
• We iteratively calibrate the simulation model and
the analytical model used for Data Fusion.
• We conclude by an analysis of the relation
between Active Travel, Public Transport and
Land Use/demographic variables.
The Central Research Question
How to fuse data from social media with traditional datasets to create high quality data? What role can
Geospatial Microsimulation and Agent-Based Modelling serve in this process?
Underlying Architecture of Data
Fusion
Figure 2: The typical Architecture of Data Fusion techniques.
[2]
[3] is the first paper that uses Geospatial Microsim-
ulation for the purpose of Data Fusion. The simula-
tion can display the efficacy of a given algorithm.
Application of the Technique
Figure 3: A link existing?
The relation between active travel, public transit
and Land-Use characteristics provides a rich area
for research. We aim to get a detailed picture of the
active travel occurring in our area of choice. We can
use the dataset to infer the relation of active travel
with Land-Use and Public Transit. As a conclusion
we hope to demonstrate the relation between these
elements.

13. 1. Introduction
India ranks high in road traffic fatalities. India has the 2nd largest road network in the World[1]
but lags qualitatively[2]. A report[3] based on in-depth crash data highlights that all fatal crashes
in urban Kolkata (Nov’14 to Nov’15) had at least one infrastructure factor contributing to its
incidence. My research study aims to identify and address such factors in a junction in the city
of Kolkata, India.
4. Location identification
o Identify one location from 516 crashes with GPS locations
• Should have high accident incidence
• Be a typical junction to develop a template for transferability

6. Intervention development
o Literature review for possible solutions to identified problems
o Develop relevant interventions based on local conditions
• CAD will be used for design, if required
• ARCADY/LinSig to be used for intervention assessment
5. Problem identification
o Registered accidents considered as “case studies” and analysed
for following crash parameters:
• Crash configuration
• Kind of accident
o Additional data to be collected on traffic volume and counts
2. Objectives
o Identify a junction with high crash incidence
o Study crashes to understand the interactions leading to crash occurrence
o Literature review to list possible solutions and develop relevant changes
o Assess the proposed changes using relevant software

Background
1. Is the length of the contract a determinant factor of
efficiency?
2. Is any different behaviour depending of the years
remaining in the contract?
Aim, objectives and data
a) Create a framework for all rail franchises to be able
to evaluate an optimum length of the franchise
b) Evaluation of each franchise to provide justifications
or expected level performance for each company
c) Provide recommendation for future actions
Quantitative analysis: econometric analysis of cost
functions Creation of a cost frontier to measure the
level of inefficiency amongst companies
Qualitative analysis: research of the political and
contextual situation of each company and franchise
Inclusion of additional value outside the data analysis
Methodology
Data analysis may offer a single case for every single
scenario, therefore the extrapolation for different
situations could be biased and mistaken. Also, a controlled
experiment or the effect of changing only one variable
and observe the effect is limited in reality.
In some occasions, the market decisions are not following
a procedure but different political and social agendas.
Liberalization of rail services as example of public tender
for public service contracts (Nash et al 2016)
Aiming a balance between quality of public service and
economic efficiency of the system (McNulty 2011)
Different studies in economies of scope and scale but not
so many in length franchise
Unique variety of examples in the UK due to all routes
already privatised in this system
UK and UE currently promote tendering systems and
franchise length is a key factor
Limitations
German evidence suggest that longer franchises are cost
effective, better deals on rolling stock and incentives to
better practices are opportunities from longer deals
(Nash et al 2016).
There are to be expected differences in companies
behaviour depending on the moment on their contracts,
and also depending of their expectations to continue with
the activity.
Understanding of a system with different behaviours
depending of the context. In the decision making process,
the political and historical heritage are possibly as
important as current economic performance.
Results expected
The length of the franchise should be able to be modified
depending of the conditions of each line.
Long contracts in systems where investments are needed
and better rolling stock deals are possible.
Short contracts where the situation is about to change in
a near future, or not possible to obtain benefits from big
investments.
The flexibility in length should be another efficiency
factor. In addition, in this case, length is easier to modify
than other parameters.

17. 1. BACKGROUND
• China’s "One Belt, One Road" initiative
prompted the construction and operation of
China-Europe 'Silk Road' Rail Network.
• China is one of the largest manufacturing
centre. Trade between EU and China keeps
increasing in recent years, while about 10.1%
of the imports and 6.3% of exports in 2016
were electronic products.
• Air pollution is responsible for tens of
thousands of early deaths every year. And in
EU 51% of NOx and 20% of PM2.5 emissions
were from transport in 2015.

questionnaire. A draft questionnaire has been developed and will be pilot
tested on 30 respondents and modifications will be made based on pilot
testing.
Secondary data will be collected from academic journals, company reports and
books which will be used to define the research objectives and to explore
various facts.
Data analysis and interpretation of surveys: The questionnaire data
composed of closed rating scale questions will be compare against existing
literature and a descriptive analysis with bar charts and pie charts will be used.
THE POTENTIAL USE OF MOBILE PHONE PAYMENTS FOR TRANSPORT TICKETS
WITH PARTICULAR REFERENCE TO UGANDA.
Agaba Collins | Tony Plumbe (Supervisor) | Jeff Turner (2nd Reader)
1. Motivation
There’s a growing use of mobile phones for the
payment of utilities and other services in Uganda
and this service could be used for the payment of
public transport tickets.
Currently, Public transport in Uganda operates on
manual based system which poses challenges like
retrieval of information and planning for public
transport in Uganda.
My international experience with cashless
payment for transport tickets showed me that a
solution could be provided by using mobile phone
payments which will benefit public transport users,
operators and the government.
2. Research Objectives
• To review and access the merits of smart ticketing
and applications in the world today.
• To assess the acceptability and likely behavioural
responses to introducing bus mobile phone
ticketing in Uganda.
4. Case Study Area
3. Scope
6. Methodology
Focus will be on mobile phone payment for travel
tickets for intercity 67 seater coaches.
There are other means of public transport for example
14 seater mini buses and 32 seater coaster buses that
operate between the two towns, this study will not
include them.
The study is confined to daytime coach travellers
between two towns Kampala and Mbarara – Uganda
for the period between May and June 2017.
5. Current applications
7. Expected outcomes
• Measurement of the acceptability for mobile phone payment for transport
tickets in Uganda.
• Analysis of the likely travel behaviour should mobile phone payments for
transport tickets be introduced in Uganda.
• An analysis of the benefits, importance and challenges of adopting mobile
phone payment for transport tickets in Uganda.

1. Research Context
Despite a raised profile in recent years the modal share for cycling in
West Yorkshire is 0.8% of all commuting trips, half the national average
(Rogers, 2013).
CityConnect is a £6m cycling infrastructure/promotion programme
managed by West Yorkshire Combined Authority and funded by the
Department for Transport
It aims to make cycling “the natural choice for short journeys”
The first physical leg, CS1, opened in June 2016 from west Leeds to
Bradford
By February 2017, 100,000 trips had been made on CS1, but limited
work has taken place so far to gauge usage by local residents.
2. Transport and identity theory
Traditionally, predictions of transport mode choice have been based on cost,
time and effort (Van Acker et al, 2013). However, these theories don’t ex-
plain differences in transport choices by “individuals in similar situations
and with similar socio-economic circumstances” (Heinen, et al 2011; Hei-
nen, 2016).
Now, a burgeoning body of work “suggests that decisions to cycle are af-
fected by perceptions of ‘bicyclists’ in the community, and whether or not an
individual wants to be identified with that group” (Sherwin, 2014).
“Transport identities, social-role identities, self-identities and place identi-
ties are important predictors of mode choice and change” (Heinen, 2016).
Identity theory in transport can be largely ascribed to :
cultural identity (e.g. ethnicity)
social identity, indicating identification with a group or social category
(Tajfel and Turner, 1986), i.e. a link between the self and social structure
(Stryker, 1987).
Self identity, or the meaning that individuals attach to themselves
(Heinen, 2016). A value set rather than a role.
The identities that local residents assume and/or subscribe to may there-
fore have an influence on their transport choices and use of CS1.
Increasing cycling could:
Enhance air quality
Reduce congestion
Increase access to services
Improve physical and mental
health
CityConnect - Cycling and Identity in Leeds
Daniel Gillett, MSc Sustainability in Transport, pt08djg@leeds.ac.uk Supervisors – Eva Heinen and Caroline Mullen
5. Application of findings
West Yorkshire Combined Authority’s Transport Strategy and the Leeds City
Council Interim Transport Strategy both support the goals of the Strategic
Economic Plan for West Yorkshire, which aims to achieve “good”, or sustaina-
ble, growth for the region.
As both transport documents pledge to increase cycling levels, a deeper un-
derstanding of why people do or do not cycle will be desirable when encourag-
ing behaviour change, even where segregated infrastructure is provided.
Work done to understand the role that identity can play in making the decision
whether to cycle, not cycle, or opt for a different transport mode could there-
fore potentially be used to inform promotional campaigns or individual inter-
ventions designed to encourage cycling and address identity roles or values
which might obstruct positive decisions on travelling by bike.
3. Research Goals
This dissertation uses identity theory to explore the extent to which identity
can influence the decision to cycle and might influence the patronage of CS1.
As a comparatively risky area to cycle (Lovelace, 2016), many people in West
Yorkshire cite danger as a barrier to cycling. CityConnect aims to challenge
this be providing dedicated, segregated infrastructure.
Therefore, it will be worthwhile to investigate whether identity remains an in-
fluential factor in the decision making process even when cycling provision is
promoted as “safe”. Considering that the scheme also attempts to normalise
cycling through promotional or “soft” measures, the data may also provide
some insight into potential promotional measures specific to the area.
Key Research Questions
Who do residents living along CS1 perceive as cyclists? Who is cycling for?
Who cycles?
Do residents’ social identities (i.e. their societal roles) or self identity (i.e.
their personal values) influence their decision to cycle?
Would it be acceptable within a resident’s direct, less-direct and wider so-
cial circles to identify, or be identified, as a cyclist?
4. Methodology
(IndicesofDeprivationexplorer2015)
As CS1 passes through a diverse range of communities, there
is likely to be a valuable assortment of social identities and
identity values among residents.
i. Overview
This research will follow a qualitative approach based on a grounded theory meth-
odology, and comprise of interviews with residents living close to CS1. As notions
of identity involve emotional elements, the aim is to collect lived experiences of the
social world, so a qualitative approach is justified (Liamputtong and Ezzy, 2005; Bei-
rão and Cabral, 2007; Grosvenor, 2000).
ii. Literature review
Literature will be reviewed in further detail to inform questioning and establish an a
priori knowledge base for use in inductive data analysis.
iii. Sample design and selection
The research sample will comprise residents living close to CS1. 10 regular cyclists
and 10 non-cyclists make up the target sample, but a saturation strategy may be
used to gain more data. Non-cyclists will be useful for exploring the identity deter-
minates that might inform transport decisions, while existing cyclists will provide
value by illuminating the identity roles and values held by cyclists. This will allow
comparison of similarities or differences between the two groups.
iv. Recruitment
The recruitment strategy will focus on attracting participants primarily through: so-
cial media; leafleting; announcements at community groups; contacting cycling
clubs/campaigns, and; comms with the CityConnect team.
Some demographics may be difficult to recruit, with any limitations noted and dis-
cussed in the analysis.
Participants will be interviewed using a semi-structured script informed by the litera-
ture review and research questions. Semi-structuring will allow participants to convey
authentic feelings that might not be touched upon using a rigid question structure.
Interviews will take place in a location where the participant feels comfortable talk-
ing, which may be a public space such as a café or community centre.
vi. Analysis
Analysis will follow an inductive Grounded Theory methodology (process taken from
Strauss and Corbin, 1998).

In many developing countries, shopping is one of the
main reasons for traffic congestion, due to the lack of
parking restrictions around the shopping centre.
While it is widely accepted that shopping can contribute
significantly to the congestion (Kumaat et al, 2015), there
is often no evidence of quantification of the impact.
Weekly holidays of shopping centres at different parts in
Dhaka helps to analyse the changes in traffic speed and
congestion.

21. Structural Performance Assesment Method on National Road Network
Case Study : Semarang National Road, Indonesia
Student : Hardiansyah, Dian ; Supervisor : David Rockliff ; Second Reader : Chandra Balijepalli
Background :
• Indonesia Integrated Road Management System (IIRMS) nowadays
only consider pavement functional aspect to determine road
maintenance program.
• The system is perceived to be less qualified since structural problem
may occur under a good visible surface condition
• North coast line National Road on Central Java Island has been one
of the busiest roads with High Traffic Volume in Indonesia.
• Inappropriate road maintenance methods on National Road in
Indonesia bring various defects to pavement condition.
• Road Defects inevitably cause huge traffic congestion on National
road and disrupt the smoothness goods and services’ distribution
around the area, causing huge economic loss.
Objectives :
• Identify factors affecting pavement structural performance
• Analysing the structural performance of particular National Road in
Central Java based on Back Calculation method using the data of
FWD (Falling Weight Deflectometer) survey
• Assessing pavement layers structurally with the support of ELMOD 6
(Evaluation of Layer Moduli and Overlay Design) software.
• Determining the suitable maintenance based on existing structural
pavement performance resulted from the assessment.
Research Questions :
• What are the things that need to be considered on
assessing pavement structurally?
• How to assess road pavement structurally instead of
functionally?
• What is the appropriate maintenance method based on
the result of structural performance assessment?
• Can what we do in Indonesia be improved by introducing
techniques used in other countries?

Assessing Driver Behaviour to Improve Safety on Roundabouts
using Speed Profile Data of Naturalistic Study
Introduction
The application of roundabout junctions have been mushrooming around the
world.
The main aim of roundabout design is to induce driver behavioural response that
might lead to speed reduction and homogenous speed profile (Silva and Seco,
2005).
To understand driver’s behaviour changes dealing with roundabouts is important
to ensure the effectiveness of roundabout design, especially its correlation with
safety driving.
Speed determines the possibility or the risk for an accident to happen and
contributes to the severity of crash (Elvik et al., 2004).
Naturalistic Driving Study provides wider opportunity answering several questions
in driving behaviour and safety analysis such as the relationship between driver,
vehicle, road and other traffic participants in ordinary situations, in conflict
situations and, more rarely, in some actual crashes (Barnard et al., 2015).
The current study optimises data from a naturalistic study namely UDRIVE that
gathers a large scale of data on everyday driving and riding (day-to-day basis).

Speed Profile Analysis
Qualitative and comparative analysis using some statistical measures: speed variation, the
mean of the 85th percentile speed, the interquartile range of the 85th percentile speed,
average speed values, and variance of the sample.
Limitations and Assumptions:
1. Observe two-lane roundabouts and free flowing cars that
take the second exit only.
2. All drivers are assumed driving in normal driving situation
(undistracted).
3. Engineering (geometric) details, pavement surface quality,
on-site safety measures, weather, and land use around the
roundabouts are ignored.
• Focus on roundabouts in
the UK, urban and rural
samples.
• Because of the data
collected from vehicles that
ran freely, the roundabouts
are selected in which the
sample size is high.
Expected Outcomes/ the use of the study:
1. Effectiveness of the roundabouts regarding speed reduction and homogeneity.
2. Provide more inputs for engineering design process (e.g. by comparing the study results
with built-geometric details).
3. Possibly informs the needs of safety measures implementation at roundabouts.
1. How does every type of road user perform their behavioural changes
influenced by roundabouts? Does each type of road users perform different
speed patterns on roundabouts? Has the homogeneity been achieved?
2. Does each roundabout have different performance level to induce driver
behavioural response that leads to driving speed reduction? How much the
differences?
25. Introduction
It is widely recognized that there is a need
to increase the proportion of trips on active
modes in our towns and villages. West
Yorkshire has set as a target for 2026 to
increase trips walking 50% and double
cycling (WYCA, 2016). However, in The
Upper Calder Valley, this aim could seem
more challenging than in other areas of the
region, due to its high gradient, urban
discontinuity, and longer distances to
certain services among others constraints.
Objectives
• Analyse quantitatively and qualitatively
capability to access to key services
using active modes.
• Investigate policies, which are more
likely to promote and improve
accessibility in active modes, given
the previous mixed method analysis.

There is not much evidence on showing how travellers perceive the time
as effective when travelling. The effective use of travel time may also vary
upon the travel mode, as different stages arise at each mode.
Previous research: based on the productivity of travel time (studies
frrom Hensher, Batley).
- Mostly centred on the trade-offs on time savings, rather than in the
effective use of travel time due to particular trip conditions.
- ‘Journey time savings in rail trips led to increased productive time for
business travellers, but also to a reallocation of time use’ (DfT, 2009)
Further elements such as saved time, as well as access and egress times,
among others, may influence the effective use of time across all modes. As
the mentioned elements have not been directly assessed before, these will
be included in this study.
The aim of this project will be based on a cross model comparison, in order
to gain a better understanding of travellers’ modal choice decisions on
medium and long range trips within the UK.

SURVEYS
(I). How travellers used their time during the trip
- Categories covering potential answers
(II). How useful time was, as perceived by travellers
- In competing modes, compared to not travelling,
then determining a common reference level.
(III). How useful each trip stage was
Based on interactive surveys, obtained through the interception of intercity
travellers at the targeted corridors.
Due to the reduced number of commuters at the chosen corridors, only
business (dark grey) and non-work (light grey) trips will be considered.

and car. Final report to Virgin Trains and Fishburn Hedges.
The input values will be the passengers perception of the use of travel time,being
this split into time blocks (different stages of the trip,varying across all modes) and
assessing to what extent each of these time blocks would be useful, in reference
to a common established level (not travelling scenario).
The output values will be how effective the travel time would be for the whole
trip in both scenarios under comparison, as compared to not travelling case. As
well, how passengers used their time will be cleared with the data collection.
(III)
Contrast how much time is perceived as useful
time across the different modes.
27. BACKGROUND
Airport is no longer seen as transportation node, but it
transforms into airport city. Recent studies (Guller and
Guller, 2001, Freestone, 2009, Kasarda, 2008) view airport
city as a global phenomenon which emphasises on the
commercial sector
The agglomeration of airport city becomes an aerotropolis.
This concept is a new urban form where airport city
becomes the centre, and there are various of activity
cluster along transport corridor.
Though, there is a wide range of airport-driven
development concept given by academia. However, the
implementation of the concept itselft might vary among
stakeholder, take for example the different view among
actor in Peneda et.al’s study (2011).
Due to the new phenomenon and complicated process
which involves various stakeholder, there will be a
tendency that the implementation of aerotropolis might
differ from what academia think.
RESEARCH QUESTION
“How is the concept of airport city or
aerotropolis perceived by planners?”
OBJECTIVES
To identify different planners’
perceptions about the concept of
airport city or aerotropolis
CASE STUDY
Soekarno-Hatta airport is
located in Banten province in
Indonesia. Currently, the
Soekarno-Hatta airport is
planned to be an aerotropolis
area with a land area of 4345
Ha. The development aims to
be the economic catalyst for
the surrounding area and
increase its competitiveness
among ASEAN airports.

Preliminary Comparison
Delivered Schemes
(Note: Boxes in white: data in 2015; Boxes in blue: data in 2016; Boxes
in yellow: Downward trend in running time)
➢Bus Lane Widening (5): Re-align road marking to accommodate widening of bus lane
➢Yellow Box Marking (3): Criss-cross yellow lines painted on the road
➢Keep Clear Marking (2): Do not block that part of the carriageway indicated.
➢Review Parking (1): Part-time parking is potentially obstructing the bus route during peak hours
➢Centerline (3): Moving the road centerline to assist traffic pass bus stops or curbside obstructions.
➢Signage and Enforcement (1): Install signage to prevent general traffic entering, enforce bus lane
facility.
➢Signage and Line Marking (1): Move the locations of part-time on-street loading bays to allow space
for vehicles to maneuver around safely.
➢Signal Modification- SCOOT (1): Converting existing signal system to Split Cycle Offset Optimizing
Technique (SCOOT).
• To quantify the benefits of all 17 bus priority interventions implemented on London
bus Route 3 and compare them with their predicted values.
• To assess the reliability of London bus Route 3 after the bus priority interventions
implemented.
• To compare cost of schemes with effectiveness and carry out an Cost-Benefit
Analysis (CBA).
• To identify potential problems and reasons lead to the difference between predicted
and actual benefits, propose measures and explore more efficiency schemes.
In 2015, based on a review of the existing evidence, a guide to the effectiveness of
26 different types of bus priority interventions produced by TfL. TfL applied this
guide to forecast the effectiveness of various schemes at pinch-points on the
network of London, in terms of the savings in expected journey times, variety and
delays. A majority of bus priority schemes have completed since December 2016,
and actual monitoring data collected by Tfl is available now.
The target route is London Bus Route 3. According to the bus service usage
report published by TfL, the usage of Route 3 has experienced declining for three
consecutive years since 2013, it is significant to take measures to make Route 3
more attractive. Since 2015, 17 bus priority schemes have been implemented
along side the bus route to improve effectiveness and reliability.
Social influence, how many
passengers and inhabitants can
benefit from these schemes?
How much?
Will the increased/improved
reliability of Route 3 be realized
by passengers? How could
Route 3 attract passengers who
gave it up previously?
What types of factors could influence
the service reliability? How to estimate
the effects of different factors on
service reliability?
