Functions of public transport Which functions in public transport need position: Disposition Real Time Passenger Information Dynamic Schedule Synchronization Transit Signal Priority Transit Signal Priority (TSP) is still dominated by infrastructure based system If onboard intelligence can satisfy the requirements of TSP, the infrastructure is dispensable, which leads to significant cost savings. Performance improvement with GNSS can make PT more attractive 4
Not only PT
Project aims 1. Development of RPP (Robust Positionning Prototype) device for PT vehicles posotionning purposes 2. Assessment of RPP and different TSP scenarios with microsimulation tools (VISSIM)

Summary RPP fulfils precision and reliability requirements RPP might be used fo passenger information and TSP one unit, multiple use lower cost of whole system (around 20%) compared to infrastructure based TSP higher elasticity (comparing to induction loops) as well as precission and reliability (compared to available GNSS)
Possible aplications possible to use in new TSP systems especially useful in buses change of route, bus detection on separated and common lanes floating pre-emption point constant travel time from pre-emption point to stop line, instead of constant distance continuously updated vehicle position continuous positioning data transfer limits
