Adaptive Reuse Heritage Building converted to the Hotel Building, AR-HB-hotel, effects changes and impacts in several aspects. There have been established criteria for substantial renovation, business investment and assessment of the value of heritage buildings but no concern has been paid to the surrounding community impact. As heritage buildings are worth preserving, their value is one significant issue that we have to consider.Heritage is valued in a variety of ways and the value is driven by different motivations: economic, political, cultural, spiritual, aesthetic. The objective is to study four issues of AR-HB-hotel focused on (1) physical, (2) economic, (3) value changes, and (4) social impacts. The research method is mixed qualitative and quantitative study. ‘Bangkok Story Hostel’ was selected as a representative case for AR-HB-hotel. This ...

PPP is aimed at mutual benefits from both private and public sector. PPPs have been an important tool for implementing infrastructure and mega-projects both of developed world and developing countries since four decades ago, especially transportation projects. In Thailand, PPP Transportation projects have played a role in the two sectors, including Toll Road/Expressway sector and Mass Transit sector. Although there has been a number of projects completed through PPPs, and there has been a movable legal framework in place for PPPs. The regulatory and legal framework surrounding PPPs for infrastructure delivery is incomplete, outdated, and fragmented in Thailand. Therefore, the objective of this paper is to investigate the public-private partnerships in Thailand, towards Tollway Road/Expressway transportation project to outline the practices and its issues from Thailand project.

In comparison to bus, passenger van offers shorter journey time, increased headway, improved reliability, higher levels of comfort, less frequent stopping, guaranteed seating and air conditioning. The objectives of this paper are to investigate the preferences of public transit users in general, and passenger van users in particular, towards several service quality attributes, and to exploit such insights in the planning of future services. The main Stated Preference (SP) surveying techniques were based on 1200 passenger van users which were drawn from three strata pertaining to different spatial locations, specifically inner-city, urban-fringe and suburban. The analysis was exploited the merger of the various SP experiments and the phenomenon of repeated observations.

The pedestrian crash zones are based on the road and physical environment, vehicle and driver behavior and pedestrian behavior, especially the area around the school. Therefore, this paper would like to improve safety by identifying crash area through Geographic Information Systems (GIS). Objective: The objective of this paper is to identify pedestrian crash zones of primary schools and secondary schools in Bangkok, Thailand through the spatial analysis and GIS tool. Method: The research methodology was the data collection from pedestrian-vehicle crashes in 2016 at 12 schools of 1,218 locations in Bangkok. The data analysis used GIS for geocoding the crash locations. The spatial patterns and pedestrian crash zone map were applied by Moran’s I statistic and the Kernel Density Estimation (KDE). Results: The Moran’s index showed that the accident locations ...

The present research about student drop-off and pick-up behaviors and spatial analysis will be helpful for better understanding school traffic incidents and related risk factors. Objective: To examine the risk factors associated with school drop-off and pick-up in three dimensions: 1) risk zones, 2) risk behaviors, and 3) risk periods. Method: A mixed method approach was employed using 4 sets of data, consisting of 1) the statistics of accidents occurring around primary schools, 2) the student drop-off and pick-up behaviors, 3) the opinions toward risk zones and risk periods, and 4) the data obtained from the survey and interview. The spatial analysis was conducted using kernel density estimation technique. The statistical data analysis was carried out to analyze and compare the questionnaire responses given by the teachers and...

The objective of this paper was to compare the environmental graphic designs for passengers’ decision to choose walking ways in subway stations of Bangkok Metropolis, Thailand. Methods: It uses the multi-stage sampling approach at various forms of station entries-exits and traffic statistics of service usage by passengers. The forms of station entries-exits can be divided into four types: 1) Silom Station (2-way exits), 2) Sukhumvit Station (3-way exits), 3) Huai Khwang Station (4-way exits), and 4) Phahon Yothin Station (5-way exits). Questionnaires were used to collect data from 445 passengers, using Likert Scale and t-test/ANOVA. The comparative analysis of directional signs was conducted with three factors as follows; 1) signs with 1-point location, 2) signs with 2-point locations, and 3) signs with 3-point locations. Results: The resul...

Methods: The primary and secondary traffic data were collected to develop a virtual traffic simulation model with the use of the AIMSUN simulation software. The model validation method was carried out to adjust the origin and destination survey data (O/D matrix) by running dynamic O/D adjustment. The 99 replication scenarios were statistically examined and assessed using the goodness-of-fit test. The 9 measures, which were examined, included: 1) Root Mean Square Error (RMSE), 2) Root Mean Square Percentage Error (RMSPE%), 3) Mean Absolute Deviation (MAD), 4) Mean Bias Error (MBE), 5) Mean Percentage Error (MPE%), 6) Mean Absolute Percentage Error (MAPE%), 7) Coefficient of Determination (R2), 8) GEH Statistic (GEH), and 9) Thiel’s U Statistic (Theil’s U). Results: The resulting statist...

Whereas the five spatial component factors included (1) Room Volume (RV), (2) Ceiling Height (CH), (3) the Ratio of Depth to Width (Rdw), (4) Total Room Surface (TS), and (5) Percentage of Absorbing Surface areas (PAS). The research tools were the smartphones that used the applications for acoustical evaluation and speech intelligibility analysis. The Speech Transmission Index (STI), Reverberation Time (RT), and Background Noise Level (BNL) were collected by the calibrated microphone in the nine points distributed across the entire room. And also, the sounds for testing were simulated such as balloon burst, and STIPA signal via a sound generator. The Thailand Speech Intelligibility (T-SI) model was...
