Transit signal priority (TSP) is a typical strategy used to reduce the delay in public transit and it has been used extensively to improve the transit operations in urban traffic systems. This paper proposes a transit signal priority controlling method considering both the non-transit traffic benefits and the coordinated phase states for multi-ring time plan. The integer linear programming method is used to build the green time extension and red time truncation models. In the proposed model, the optimization object includes two levels: the maximum priority effect for the first level and minimum time deviations for non-transit phases for the second level. Based on this, the semi-ring structure and the backward/forward migration time parameters of coordinated phases are further presented for establishing the constraints. The overall scheme is thoroughly tested and demonstrated in a realistic experimental scenario. Compared with …
