The proposed approach combines rescheduling with network traffic control in an attempt to minimize schedule reserve times without reducing stability and thereby increase network capacity. The paper presents an overview of the approach, discusses the rescheduling process and issues that need to be addressed in order to effectively use new approach, outlines how the network should be divided to best use the new approach, and presents results of a microscopic railroad simulation that shows the approach can improve capacity, reduce delays and increase schedule stability.

This paper provides an overview of a selected group of factors that help define some of the main features of urban transport in metropolitan regions around the world. The aim is to provide decision-makers and policy analysts some basic perspective on where cities in their region sit in a global context. The paper also points to some key policy issues that emerge from the data and which have considerable bearing on issues such as priorities in urban infrastructure development. The data are drawn from the Millennium Cities Database for Sustainable Transport compiled over 3 years by the authors for the International Association of Public Transport (UITP) in Brussels. The database provides data on 100 cities on all continents. Data summarised here represent regional averages from 84 of these fully completed citie...

The paper details a methodology which is based on managing regional economic, social and environmental risks associated with major new transport infrastructure projects. The paper details: a strategic planning process which manages land use. infrastructure and financial constraints. integrated transport planning and analysis based on 'top down' international benchmarking and 'bottom up' transport demand modelling. the limitations of conventional project appraisal such as benefit-cost analysis and the development of new analytical techniques.

On the one hand there are those who see private motorised mobility or automobile dependence as a logical expression of growing wealth and as such, virtually unavoidable; the city must be adapted to almost open-ended car use. On the other hand, there are those who see private passenger transport as a major problem in cities for a whole host of reasons; car use should be kept within limits imposed by the capacity of the urban system to deliver livability and ecological integrity. Several issues are prominent in this debate such as what primarily influences a city's transport system - physical characteristics of the city or the economics of transport systems. The relative economic merits of different transport modes are also hotly contested. There are claims that non-automobile modes are discriminated against in the market place by inequitable pricing policies which subsidise private transport,...

ERTMS is designed to improve European railway service by replacing different national-based train control systems with a single interoperable system. ERTMS also increases safety by providing full supervision of train movement and increases capacity by reducing train headways. A significant benefit of ERTMS is the development of detailed digital data on railway infrastructure and operations. This data, coupled with improved technologies for managing staff and resources, provides the foundation for developing an advanced traffic management system (TMS) that can significantly improve railway efficiency and attractiveness. Banedanmark is developing an advanced TMS to achieve this goal. Banedanmark’s TMS takes a fresh approach to railway operations by creating Production Plans consisting of precisely defin...

Automobile dependency has many impacts on consumers, society and the economy. It increases mobility and convenience to motorists. It increases consumers' transportation costs and resource consumption, requires significant financial and land resources for roads and parking facilities, and it increases traffic congestion, roadway risk and environmental impacts. It reduces the viability of other travel modes and leads to more dispersed land use and mobility intensive economic patterns that require more vehicle travel for access. This paper examines macroeconomic impacts of automobile dependency (impacts on overall economic development, productivity, competitiveness and employment). Both economic theory and empirical evidence indicates that excessive automobile dependency reduces economic development. Several current market distorti...

Any disruption adversely impacts the operations, causing long delays. Many studies investigate the effect of a railway incident; however, a holistic quantification is lacking. This study aims to present an estimation framework for flexible traffic management systems, which can help reduce network delays and enable dispatchers to make better-informed decisions. An incident's impact on the network is estimated by creating a sequence of models, which predict two key variables. Firstly, the incident duration is predicted, which is used to predict the second variable: total delay caused by the incident. Various influencing attributes are examined, such as weather, network and railway-related attributes. Their relationship with the response variables is studied in order to understand the incident's impact. Using incident data from the Danish Railways, machine learning models are estimated. The results show that neural networks outperform other competing models for total delay modelling, resulting in improved prediction by the estimation framework, thus giving higher accuracy than the stand-alone models in the study.

It was with this aim in mind that SBB Infrastruktur AG launched a program called "PULS 90", Its kernel is the dynamic generation of zero-conflict timetables in real time in the event of incidents, combined with the targeted control of all trains, leading to a high level of precision in production. It has become clear that the whole planning and production process is going to need to be adapted if the maximum potential is really to be leveraged.
