Development of an Integrated Adaptive Transit Signal Priority (ATSP) and Dynamic Passenger Information (DPI) System

Transit Signal priority (TSP) and dynamic passenger information (DPI) have become two strategic technologies to attract more transit riders. Currently transit agencies have to go to different vendors for TSP and DPI systems. As a result, multiple automatic vehicle location//global positioning systems (AVL/GPS) units, computer hardware and communication links need to be installed on a single bus. An integrated TSP and DPI system is needed to reduce cost and complexity of system maintenance for transit operators. The project will develop a dynamic passenger information system as extension of the adaptive transit signal priority (ATSP) system as it has the key features the DPI needs. The integrated system will provide transit signal priority along El Camino Real at 51 intersections, and real-time passenger information at selected bus stations, on web or cell phones.
