Analysis of Conflict Characteristic between Early Right-Turning Vehicles and Pedestrians at Signalized Intersections

摘要

摘要: 针对在信号交叉口提前右转且无信号控制的条件下，直右混行车道上右转车受直行车阻挡的问题，根据混行车道上交通流特性，确定了交叉口信号周期内提前右转机动车无法进入右转弯道的阻断时间，结合行人流上游所受的信号控制方式，解析了机动车与双向行人的冲突过程，计算了冲突中机动车与行人的通行时间，并在此基础上，建立了提前右转方式下右转车与行人的延误模型.案例计算与分析表明：模型计算值与实际调查值之间的相对误差在20%以内；当机动车流量小于350 pcu/h，机动车对行人通行影响较小，而当机动车流量大于350 pcu/h，行人与机动车的竞争冲突较为明显.

Abstract: Vehicles turning right early at signalized intersection was prone to be blocked by the vehicles that go straight when they travel in a mixed lane shared by both right-turning and straight-going vehicles and are not directed by a signal. Based on traffic flow characteristics in the mixed lane and the effect of signal control on the upstream of pedestrian flow, the blocking time of right-turn vehicles was considered to analyze the conflict process between vehicles and bidirectional pedestrian flow. The vehicles and pedestrians crossing time were calculated, and the delay model of right-turn vehicles and pedestrians was established. The case study shows that the relative error between the calculated results and the real data is less than 20%; and when the vehicle volume is less than 350 pcu/h, vehicles have little impact on pedestrian crossing, and when the vehicle volume is more than 350 pcu/h, the conflict between pedestrians and vehicles was obvious.
