A new, more efficient bus service, Pulse, is under development for Dempster Street, a heavily traveled corridor in Chicago’s northern suburbs. Passengers will enjoy modern new stations with real-time arrival information, free Wi-Fi on buses, and faster travel between Evanston and O’Hare International Airport.
In order to help make the new Pulse service a fast, frequent and reliable travel option for passengers, Pace will implement a Transit Signal Priority (TSP) system. While the Pulse buses will be sharing the road with general traffic, TSP integrates with traffic signal controls to potentially shorten red lights or extend green lights briefly at selected intersections when buses are operating behind schedule to help buses maintain on-time performance.
Pulse buses will always be given a lower priority than emergency vehicles, and the traffic signal system will only adjust traffic signal timing if the change does not significantly interfere with traffic flow.
Pace’s regional TSP program, with support from IDOT and the Regional Transportation Authority (RTA), already shortens travel times by up to 20% on existing bus routes in Harvey, South Holland, Dolton, Waukegan, Berwyn and Cicero.
