Roads and Maritime Services has developed a system known as PTIPS (Public Transport Information and Priority System) which is a key component of Roads and Maritime Services ’s Bus Priority strategy.
PTIPS works closely with SCATS to manage traffic light timing so buses run as close as possible to their timetable. GPS (Global Positioning Systems) and radio data communications deliver information about buses and their location, which can be used to forecast the arrival time of the bus at traffic signals. If a bus is running late, SCATS can alter traffic signal timing to allow the bus to maintain its scheduled timetable, giving bus passengers a more reliable service and letting bus operators schedule their buses more efficiently.
The technology can also be used to forecast arrival times at bus stops, with the potential to provide passengers with real-time information about the arrival of their bus. Currently PTIPS provides information to a SMS service for phones to find out if the bus is on time and what its current schedule time of arrival at bus stops will be.
The initial trial was conducted and successfully run on three strategic bus corridors in metropolitan Sydney: Bondi Junction to Burwood, Miranda to Hurstville, and Liverpool to Bankstown. PTIPS is now fully operational having been deployed on approximately 2,500 state owned buses with the roll out continuing to private bus companies, when this is complete all 4,500 buses will be using PTIPS.

Sydney Light Rail
Each Light Rail Vehicle (LRV) is fitted with a transponder at front and rear which is detected by SCATS as the LRV approaches an intersection controlled by a white T light. The rear transponder terminates the T light.
Roads and Maritime Services and Ministry of Transport are working on implementing 43 strategic bus corridors across the Sydney metropolitan area.
