Samenvatting
This research focuses on utilizing existing on-board units of bus real-time information systems for bus signal priority. When a bus approach the designated intersection, the center receives information from the bus, estimates how long the bus arrives the intersection, and sends the priority request to the signal controller. The controller then chooses an appropriate signal priority strategy. GPRS network is the communication channel from bus to center and from center to controller. Three tests are included in this research, communication frequency, bus check-in range and location of bus stops, to see their influence on BSP system. For the covering abstract see ITRD E134653.
