Study of Two-Phase Bus Signal Priority Strategy on Intersection Based on Cooperative Vehicle Infrastructure

In order to reduce bus delay at intersections, this paper proposed three types of two-phase bus signal priority strategy on intersection based on Cooperative Vehicle Infrastructure, which includes green extension, red truncation and phases insertion. The delay triangle was used to analyze and infer the formulation of intersection delay variation. By taking two-phase signal control intersection as an example, the author calculated intersection's delay under unsaturated and saturated traffic conditions, and turned out to be that the strategies had positive impact.
