摘要
针对两相位信号交叉口存在的左转车流和直行车流的冲突,研究了左转车和直行车在冲突点处经历的延误。首先在借鉴无信号控制交叉口次路车流Admas延误模型的基础上,推导了信号交叉口左转车流的冲突延误计算模型;然后应用概率论、间隙理论及排队论的相关知识建立了直行车的冲突延误计算模型;最后使用烟台市的实际调查数据对两个延误模型进行了验证,其平均相对误差分别为8.93%和17.32%,说明两个模型都具有较好的实用性。
Aiming at the conflict between the left-turn vehicle flow and the straight-through vehicle flow at the two-phase road intersections,the conflict delays of the left-turn and straight-through vehicles was studied.A conflict delay model was built for the left-turn flow at the two-phase intersection on the basis of Adamas delay model for the secondary vehicle flow at the unsignalized intersection.A conflict delay model was built for the straight-through vehicle flow according to the probability theory,the gap t...
