Signalized intersection straight-going waiting area length design method and system
The invention discloses a method and a system for designing the length of a straight waiting area at a signalized intersection. The method comprises the following steps: collecting related traffic data; according to the basic relationship among the three parameters of the traffic flow and the Greilz linear relationship between the speed and the density when the traffic flow density is moderate, calculating the maximum number of straight queuing vehicles behind the stop line when the intersection is red; and finally, the number of the vehicles is converted into the average queuing length of the straight-going vehicles with meter as the unit, the maximum queuing vehicle length is calculated, and the length of the lane change forbidding line of the entrance lane is removed to obtain the length of the straight-going waiting area. According to the method, the problem of urban traffic resource waste can be solved to a great extent, a targeted improvement method is provided for the traffic jam condition at the intersection, and meanwhile the life efficiency and social traffic development can be rapidly improved.
本发明公开了一种信号交叉口直行待行区长度设计方法及系统，该方法包括：采集相关交通数据；根据交通流三参数之间的基本关系，以及交通流密度适中时，速度与密度的格林希尔兹线性关系，计算在该道路口红灯时停车线后的最大直行排队车辆数；最后将该车辆数换算成以米为单位的直行车辆平均排队长度，计算最大排队车辆长度，去掉进口车道禁止变换车道线长度，即为直行待行区的长度。本发明可以很大程度上解决城市交通资源浪费问题，并且对交叉口处的交通堵塞情况有了针对性的改善方法，同时能快速提高生活效率和社会交通发展。
