A Signal Priority Algorithm for BRT Based on Intersection Resource Integration

Article Preview

Abstract:

Real-time scheduling and signal priority strategies play a critical role in improving the service quality of Bus Rapid Transit (BRT) system. The delays of public passengers and social vehicles are essential factors that should be considered for signal priority control. This paper proposes a signal priority algorithm for BRT based on intersection resource integration from the angle of intersection time and space combinatorial optimization, which combined optimize lane functional partitioning and green ratio allocation. The results of the data validation proves that the optimization model can significantly reduce the BRT vehicle delay at the intersection, while reducing the adverse effects of social vehicles.
