System) location through satellites to BMS(Bus Management System). By using the GPS location, data on the location, driving speed, arrivals at bus stops are collected and transferred to the TOPIS Center through wireless communications network. The TOPIS Center processes the collected data and provides real-time bus operations information.
The data collected through BMS is then transferred to the
