摘要

Delay imposed on buses is witnessed at isolated signalized intersections. The major source of delay is created due to bus and car interactions. Towards reducing person delay pre-signal lights are installed at the upstream of the intersection. Pre-signal is a control tool that can manage the interaction and space conflict between cars and buses at the mixed lanes, located after the pre-signals, approaching the intersection. This paper presents an optimal pre-signal control system that optimizes signal settings based on minimization of person delay. The optimal solutions are derived analytically via Pontryagin Maximum Principle.
