Galileo Signal Priority for Public Transportation

Since global positioning systems (GPS) has reached full operational capability in 1993, the system has been taken up by public transport (PT) applications quite slowly compared to automotive navigation devices on the road. Even today GPS is used only at some installations for traveller information for tram/bus arrival time, but mostly not for demanding tasks that affect traffic light control. The current paper starts right here with the application of transit signal priority (TSP) for vehicles of PT. The focus has been put on TSP to overcome the last obstacle for a sustainable introduction of GNSS to support and improve all functions of PT. With this step the existing infrastructure based systems (which are less flexible and more cost intensive) shall be dispensable, to save on equipment and maintenance and explore the full potential of on-board intelligence. In this context the current paper has its focus on the intelligent interaction between the vehicle and the traffic light system. To show the potential performance of the new approach, the GNSS based TSP is compared to the traditional infrastructure based TSP.
