无信号交叉口可接受间隙理论模型修正分析

摘要

根据次路进口道到达车流存在左、右转弯车辆及主路交通流在交叉口处速度受影响的实际情况，对在较理想条件下推出的可接受间隙理论模型进行修正，使其更接近交叉口交通流的实际情况。%According to the actual cases that if there is left or right turning vehicle in the traffic flow entering minor road, the speed of main road traffic flow is affected at intersections, the author revises the m odel of ideal gap acceptance theory. New model is suitable more for the actual situation of intersections.
