Dynamic Green Wave Warning Design Based on Video Image Detector

目的为了使绿波带发挥更好的作用,解决硬件设备安装困难、不易维护、绿波速度固定等问题,对原有的交通绿波带设计进行了创新性改造。方法用非地埋式的视频图像检测器来代替地埋式的环形线圈检测器,并对路段进行分区,配合可变信号标志这一交通通信技术,通过爬山法等智能算法,选取了宿州市迎宾大道4个交叉口作为研究对象,构造全新的动态可预警的绿波带系统。结果结果表明:交叉口运行延误下降了20.9%,运行时间降低了22.5%,总停车次数减少了3.47次。结论采用可变信号标志将信息传递给驾驶员,符合驾驶员的心理特性,并达到了动态预警的预期目标,通过动态绿波预警设计,验证了所提方案的可行性,提高了机动车辆的通行效率。

Objective To make the green wave belt play a better role,solve the problems of difficult installation and maintenance of hardware equipment,and fixed green wave speed,the original traffic green wave belt design was innovatively modified.Methods Non-buried video image detectors were used to replace buried loop coil detectors,and the road sections were divided.Four intersections of Yingbin Avenue in Suzhou City were selected as the research objects.By cooperating with the traffic communication technology of variable signal signs,a new early warning green wave belt system with dynamic performance was constructed through intelligent algorithms such as hill climbing.Results The results showed that the operation delay at the intersection was reduced by 20.9%,the running time by 22.5%,and the total number of stops by 3.47.Conclusion The use of variable signal signs to transmit information to the driver conforms to the driver’s psychological characteristics and achieves the expected goal of dynamic early warning.The dynamic green wave early warning design verifies the feasibility of the proposed scheme and improves the traffic of motor vehicles.effectiveness.
