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 of an 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.
