A Bandwidth Maximization Model for Coordinated Tramcar Signal Priority Control Alone Arterials

Signal control intersection has become a bottleneck for the operation of the tram, however green wave control can handle this problem by means of improving the efficiency. Based on this background, this paper focuses on the optimal control strategy of the green wave of the tram. Maximizing the green wave bandwidth of the social vehicles at the intersection is the control target. There are four constraints, including speed constraint, shortest green time constraint and so on, which decide the time allocation scheme. If the control scheme cannot meet the requirements of the green wave bandwidth of tram, the control target should be changed to maximize the green wave bandwidth of tram and resolve the equation. At last, the results show that the strategy can reduce the average delay by 26.54% and increase the average operating speed by 11.66%, which has a good effect on improving the operation efficiency of trams.
