This paper aims to present and evaluate the performance
of one of the first real-time bus dispatching
system in Bangkok, Thailand. The proposed bus dispatching
system receives the real-time bus location
data from the RFID sensor network. The paper provides
the background and brief description of both
the hardware and architecture of the RFID sensor
network and the real-time bus dispatching system.
The bus dispatching system continuously monitors
the status of each bus and updates its expected arrival
time at the depot using the real-time data from
the RFID sensor network. If the expected number of
vehicles falls below the required level, then the bus
dispatching system will adjust the service headway
and vehicle/driver assignments to minimize the impact
on the service headway. The system is implemented
on one of a bus lines in Bangkok. The main
focus of the paper is to evaluate the performance of
the implemented system by comparing the bus service
qualities before and after the implementation of
the real-time bus dispatching system. One month bus
service data both before and after the system deployment
are used in the evaluation of the bus level of service.
The result illustrates the potential real-life benefit
of the real-time bus dispatching system despite
the simplicity of the timetable adjustment strategy
