Public Transport Information and Priority System
The Public Transport Information and Priority System, abbreviated PTIPS, is a group of technologies developed by the Roads and Traffic Authority aimed at providing better service times to buses in Sydney.
The bus priority system comprises a data collection and transmission system on board the bus and the centrally located PTIPS datacentre that analyses data received from each bus.
The on-board system collects location, time and route information from the fare collection system and a GPS locator. It then transmits this information to PTIPS via a data radio service. PTIPS analyses this information, and if the bus satisfies the criteria for priority it passes a priority request to Sydney Coordinated Adaptive Traffic System (SCATS) to adjust the timing of traffic signals ahead on route.
