The invention relates to an intelligent traffic light coordination control method applied to intelligent traffic, and belongs to the technical field of intelligent traffic. The method comprises the following steps: firstly, counting and obtaining the vehicle queuing length of each road of a traffic intersection during red light, and storing a main road identifier and the corresponding queuing length into a main road intersection state table; collecting images through a camera, and measuring the queuing length through a vehicle queuing length measuring module; if the queuing length of any roadis greater than a preset maximum threshold value, inquiring the main road intersection state table, and obtaining the main road identifier and adjacent upstream and downstream intersection allowable identifiers thereof; and if the allowable identifier is '1', performing coordination linkage control, and when the queuing lengths of the class A, the class B and the class C are all smaller than the minimum threshold, ending linkage control. According to the invention, vehicle congestion monitoring can be rapidly carried out, road vehicles are dredged, and traffic paralysis is avoided.
本发明涉及一种应用于智慧交通中的智能交通灯协调控制方法,属于智慧交通技术领域。本发明首先统计获取交通道路口的各道路的红灯时车辆排队长度,将主干道标识及其对应的排队长度存入主干道路口状态表中;通过摄像头采集图像,车辆排队长度测量模块测量其排队长度;若任一道路的排队长度大于预先设定的最大阈值,则查询主干道路口状态表,获取主干道路标识及其上下游相邻路口允许标识;若允许标识为“1”则进行协调联动控制,当A、B、C类排队长度均小于最小阈值时,结束联动控制。本发明能快速进行车辆拥堵监控,疏通道路车辆,避免交通瘫痪。
