WHERE'S MY BUS?: RADIO SIGNPOSTS, DEAD RECKONING, AND GPS
To increase efficiency, the Toronto Transit Commission (TTC) is exploring intelligent transportation systems (ITS), including transit vehicle priority at signalized intersections and a machine vision system which, when mounted on buses, monitors traffic and transit. Another new technology being explored is the real-time positioning system. This system allows transit agencies to locate their buses in real time and thus make more accurate predictions of the buses arrival times. It also allows these agencies to create a more efficient bus schedule. The TTC currently uses traditional dead reckoning (DR) and signpost technologies for position determination. However, this technology has a number of limitations. This article details the workings of an integrated positioning system that overcomes these limitations with a combination of a low-cost autonomous Global Positioning System (GPS) receiver with DR and signposts.
