The invention discloses a method and a system for reducing road vehicle congestion, relates to a method and a system for reducing congestion by changing the state of a signal lamp and providing a suggested vehicle speed, and aims to solve the problem that a road optimization scheme cannot be provided in the prior art. The method comprises the following specific steps: step 1, collecting signal lamp information and vehicle information on a road; step 2, calculating a congestion coefficient corresponding to each group of traffic lights according to the number of vehicles passing in the change period of each group of traffic lights and the total number of vehicles on the road in the change period of each group of traffic lights; if the congestion coefficient corresponding to the last group of traffic lights exceeds a set congestion coefficient threshold value, executing the step 3; otherwise, repeating the step 2; and 3, changing the red light duration time and the green light duration time in the change period of the next group of traffic lights, and returning to the step 2.

    本发明的一种减少道路车辆拥堵的方法及系统涉及一种通过改变信号灯状态和提供建议车速减少拥堵的方法和系统,目的是为了克服现有技术不能提供道路优化方案的问题,其中方法具体步骤如下:步骤一、采集道路上的信号灯信息和道路上的车辆信息;步骤二、根据每组红绿灯的变化周期内通过的车辆数量和每组红绿灯的变化周期内道路上的车辆总数,计算每组红绿灯对应的拥堵系数;如果上一组红绿灯对应的拥堵系数超过设定拥堵系数阈值,则执行步骤三;否则,重复执行步骤二;步骤三、改变下一组红绿灯的变化周期内红灯持续时间和绿灯持续时间,并返回步骤二。
