The invention discloses a green wave band traffic control method and system for an urban road. The method comprises the steps of: obtaining the real-time road condition image data of a road; analyzing and processing the road condition image data to obtain traffic flow information; according to the traffic flow information, calculating and obtaining a green wave band control signal of a corresponding optimal performance index; updating the green wave band control signal, and generating a latest green wave band guide signal; and sending the generated latest green wave band guide signal to a vehicle on a road in front of the traffic signal lamp in a wireless signal form. According to the method, the problems that in the prior art, the anti-interference performance of a green wave band technology is poor, the traffic efficiency of a road cannot be guaranteed under the condition of large traffic flow such as morning peaks or evening peaks, the effect of transmitting vehicle speed information guided by the green wave band is poor, and the purpose of improving the traffic efficiency of the road cannot be achieved are solved.

    本发明公开了一种城市道路用绿波带交通控制方法和系统,其中,所述方法包括:获取道路的实时路况图像数据;通过所述路况图像数据分析处理以获取车流量信息;根据所述车流量信息计算获取其对应的最优性能指标的绿波带控制信号;更新所述绿波带控制信号,并且生成最新的绿波带引导信号;将生成最新的绿波带引导信号以无线信号的形式发送至交通信号灯前段道路上的车辆内。该方法克服现有技术中的绿波带技术抗干扰性能差,在早高峰或者晚高峰等车流较大的情况下,就无法保证道路的通行效率,而且绿波带所引导的车速信息传递的效果不佳,无法达到提高道路交通通行效率的目的的问题。
