In order to reduce the bus delay due to the meeting of several buses from different phases at an intersection with arterial coordination, a multiple-phase bus signal priority (MPBSP) strategy without damaging the coordination of green wave band is proposed. In this strategy, "proximity principle"is presented to settle the conflicts among priority requests for multiple phases and determine the optimal priority sequence. Then, a multiple-phase bus priority control procedure is established. As the bus with highest priority may belong to different phases, the green extension and the green-early-start are adopted to respectively establish the coordination phase and non-coordination phase BSP (Bus Signal Priority) algorithms. Finally, by taking two neighboring intersections on arterial roads in a city as case studies, the effectiveness of the proposed strategy is verified through VAP in VISSIM. In addition, the MPBSP strategy is compared with the non-BSP and single phase BSP ones. It is found that the MPBSP strategy can reduce all the bus delays of road networks more efficiently and limit the increase of average delay of general traffic.
