    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.
