A GPS-Based Dynamic Bus Signal Priority Scheme using Rolling Optimization Strategy

By receiving the global positioning system (GPS) information of buses approaching an intersection, the traffic signal schedule of the intersection can be adjusted to give priority to these buses, thus reducing the average travel delay per passenger. In this paper, a rolling optimization algorithm is proposed to set up the traffic signal schedule with bus priority of an isolated road intersection. The rolling optimization procedure is repeated at regular time intervals, where the bus arrival time approaching the intersection is first estimated and an optimized signal schedule for a certain number of time intervals is generated to minimize the average delay per passenger. As the schedule may be changed at the next optimizing interval, the transits meant to arrive in the next interval are giving a larger weight than other transits. The rolling optimization algorithm considers both the long-term and short-term performances and generates optimal signal schedules with bus priority which is then implemented via the local traffic controller for intersection signal setting.
