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 Közlekedéstudományi Konferencia Győr 2014

Cost/Benefit Analysis (COBA) • Input from microsimulation – time losts

• Other data – unit cost of passengers – unit operational cost – unit investment and maintanance costs

• Scenarios assessment – passenger costs – operational costs – investment and maintanance costs


20

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
