| Abstract | Taxi has been one of the most convenient means of transport when people have to travel off the route and in their convenient time. In addition, tourists always find it very comfortable to tour around the places via taxi. However, there have been some issues on taxi services such as passengers do not get taxi service at the location and time they want, conversely taxi do not get passengers at their location and also the driver may reject passenger with various reasons. As the issue on rejecting passenger, we had some assumption thattaxi driver may have its own preferences on the direction where the driver want to go or service zoning. By understanding taxi driving behavior, trip/travel characteristics, it might help to solve such issues. The modern day taxis are installed with GPS tracker which would record various spatial and temporal state of the vehicle throughout the day. In a long run, the accumulation of the data (Probe data) from many taxis produce significant information which could be a powerful source to uncover many facts about travel behavior as well as travel characteristics. Probe data can also be used for detecting travel pattern, detection of congestion points or demand prediction. Travel characteristics can be extracted by statistical and spatial analysis of the Probe data from GPS enabled vehicles. However, such statistics would not provide the whole picture as it is lacking of taxi drivers’ characteristics. Questionnaire survey could be used for gaining understanding about drivers’ characteristics as well validation data for further analysis. In this study, the aim is to study the taxi service behavior, identify taxi service zone and to understand the travel characteristic of taxi service behavior in Bangkok metropolitan area using questionnaire survey and taxi probe data for better understanding of taxi services as well as providing recommendation for the services. 400 taxi drivers operating in and around Bangkok were interviewed with 40 different questions covering personal, travel related, financial and usage of mobile application to understand taxi drivers’ characteristics and service behaviour. Similarly, service behaviors were extracted using Probe data from 10,000 taxis. A two way t-Test was then performed to compare the results obtained from two sources and find statistically different from each other. A pilot study was performed around Mo-Chit BTS station to extract travel characteristics of taxis. After confirming similarity and usefulness of taxi probe data and survey, full-scale zoning analysis has been conducted by firstly based on geographical boundary of Bangkok administrative zones and service operating location. As the result, three types of taxi service zones including isolated zone, interactive zone, special intersection service zone and target zone were discovered. Travel characteristics were calculated and analyzed at different criteria, such as weekdays, weekends and various time window of a single day. Result of characteristics were illustrated that there were some similarity and some dissimilarity in the characteristics among each type of zones. The revealed zone and its definition could be a good initiative for further development of policy for taxi services and providing a better service for passenger. |
