| Summary: | 碩士 === 義守大學 === 材料科學與工程學系碩士班 === 94 === The whole framework of planning and designing for mass transportation system has been significantly transformed by virtue of Advanced Public Transportation System (APTS) and Advanced Traveler Information System (ATIS). Because of the two influential mechanisms, the operational efficiency of mass transportation service providers has been improved, the incidence of traffic jam has been reduced, and passengers can have access to real-time travel information. Moreover, the two systems are also used to change Transit Trip Assignment so that the passenger’s route selection can be altered to meet his or her needs. The application of APTS and ATIS greatly influence the selection of transit modes and Transit Trip Assignment, especially in a city with various transit options.
Under the two systems, the bus dispatching station can arrange transfers and adjust headways according to the arrival time of buses. Furthermore, in a city with MRT and bus transportation system can be provided with instant information about transfers, the estimated arrival time of the target transit mode for transfer and the choices of transit modes. In terms of management and operation, trip assignment analysis can show the changes of each route’s passenger traffic and forecast the influences on the bus transportation system when a new system comes into play. Therefore, the variation of passenger traffic can be under control before the new system starts so that the operation plan of the multi-modal transportation system is more capable of satisfying O-D demand.
The main focus of this present study is Trip Assignment Model for Multi-modal Advanced Public Transit Systems. The factors which influence the selection of transit modes and routes under APTS and ATIS are taken into consideration. Threshold Value theory is take advantage of to eliminate the trips which don’t need a transfer from bus to MRT by considering the difference of the number of transfers, ticket price cost, waiting time and in-vehicle time. Then ATIS concept is conducted to recalculate passenger’s total travel cost. Based on Minimum Path Cost Theory, the passenger will choose the path with the lowest cost. Therefore, the establishment of trip assignment model is completed.
This study simulates a route network to test Trip Assignment model for Multi-modal Advanced Public Transit Systems in Kaohsiung city, and applies four operation models respectively with or without information system and with or without ticket price discounts to the network for analysis. This study finds that without dynamic information system, up to 22.6% of bus passenger traffic will be transferred to MRT, but with dynamic information system, about 10% of transfers are deductible. The current ticket price discounts don’t have any influence on traffic transfer. With information system, 59% of passenger’s total travel cost can be saved. Nevertheless, if the bus travel time is too long, the bus route and the MRT path are parallel or overlapping, the bus route is too curvy, or the bus station and the MRT station are located at the same place, the bus passenger traffic may be transferred.
