The invention discloses an intersection straight-going waiting area design and verification method based on regional traffic, and the method comprises the following steps: determining a researched regional intersection, and collecting related traffic data, including a signal lamp timing period, the size of the intersection, and the vehicle driving direction and vehicle flow in each time period; a Greenberg logarithmic model is adopted, the speed of vehicles on a lane at a stop line of an intersection of the intersection is calculated, the queuing length of straight vehicles in a red light interval is calculated in combination with the actual situation of intersection signal timing, the length of a lane change forbidding line of an entrance lane of the intersection is removed, namely the length of a straight waiting area is obtained, and an optimization scheme is obtained; and substituting the obtained optimization scheme into a SUMO simulation file, modifying the original road network, and verifying the rationality and effectiveness of the optimization method by adopting SUMO modeling. According to the method, the traffic capacity of the straight-going phase can be remarkably improved, the purposes of reducing the average delay of vehicles and relieving traffic congestion at the intersection are achieved, and a reasonable verification design method is provided.

    本发明公开了一种基于区域交通的交叉口直行待行区设计与验证方法,步骤如下:确定研究的区域交叉路口,采集相关的交通数据,包括信号灯配时周期,路口大小,各个时段车辆行驶方向与车流量。采用格林伯格对数模型,计算在该道路口交叉口停车线处车道车辆的速度,结合交叉口信号配时的实际情况,计算在红灯间隔内直行车辆的排队长度,去掉交叉口进口道禁止变换车道线长度,即为直行待行区的长度,得到优化方案;将所得优化方案带入SUMO仿真文件,对原路网进行修改,采用SUMO建模验证优化方法的合理性与有效性。本发明能显著提高直行相位的通行能力,达到减少车辆平均延误、缓解交叉口交通拥挤的目的,并且提出了合理的验证设计方法。
