OPTIMIZATION OF BUS STOP ALLOCATION AND TIME SCHEDULING USING MOBILE CDR AND BUS GPS TRAJECTORY DATA

摘要

Many developing countries, public bus transportation is a primary transportation mode for daily commuters in the city. The efficiency of public bus transportation service is important to local government for public safety and energy saving. The main objective of this study is to understand current public bus transportation problems in Yangon city and propose a new optimized method for allocation of bus stops and their appropriate time schedules. In this case study, we used origin-destination matrices derived from one-week mobile call detail record (CDR) to understand travel behavior patterns in the city. We also conducted Web-GIS based smartphone application to collect bus passenger counts and bus GPS trajectory data to determine the passenger in-out volume and traffic congestion status along the bus routes. Finally, we build a GIS model to determine the optimized bus-stops locations and their time schedules based on pre-defined a set of rules such as origin-destination trips (travel demands) by bus-stop served area, transit facility, passenger volume, traffic congestion status and other public facility locations (i.e. offices, shopping centers, etc.). We hope that this case study will help to Yangon Bus Service (YBS), a major bus transportation service in Yangon city. Myanmar.
