The invention discloses an advanced right turn length design method and device based on a traffic flow moving trajectory diagram, and the method comprises the steps: collecting related traffic data, converting the obtained total traffic volume into equivalent standard car traffic volume, calculating the saturation flow of a right through lane of an intersection according to the limit time headway, and calculating the right turn length of the intersection according to the saturation flow. Establishing a Greilz linear relation model, obtaining the relation between the speed before entering the entrance lane of the intersection and the green light passing speed of the entrance lane of the intersection, and obtaining the relation between an aggregation wave and an evanescent wave according to a traffic flow moving trajectory diagram, so as to calculate the traffic flow evanescent time of the right through lane of the intersection. Then the maximum number of queuing vehicles in the right-turn lane during the straight red light period is calculated, and finally the maximum queuing length of the right-turn lane of the entrance lane of the intersection is obtained, and the length is the distance from the stop line to the advance right-turn line. According to the invention, resource waste caused by vehicle jam at the intersection is effectively relieved, the problem of shortage of urban vehicle resources is relieved, and the travel efficiency is effectively improved.
本发明公开了一种基于车流运行轨迹图的提前右转长度设计方法及装置，采集相关交通数据，将获得的总交通量折算成当量标准小汽车交通量，根据极限车头时距，进而计算出交叉路口右直行车道的饱和流量，建立格林希尔兹线性关系模型，得出进入交叉口进口道前的速度与交叉口进口道绿灯通行速度之间的关系，根据车流运行轨迹图，得出集结波与消散波之间的关系，从而计算出交叉口右直行车道车流消散时间，然后计算出在直行红灯期间的右转车道最大排队车辆数，最后得出交叉口进口道右转车道最大排队长度，该长度即为停止线到提前右转线的距离。本发明有效缓解了交叉路口处因车辆堵塞引起的资源浪费，缓解城市车辆资源紧张问题，有效的提升出行效率。
