The invention relates to a signal intersection illuminance setting method, belongs to the technical field of traffic management control, and solves the problems that the existing street lamp illuminance is set according to a fixed value and cannot adapt to different signal intersections and different traffic environments, so that the vehicle speed change is large when a driver enters and exits a signal intersection, and the driving safety is influenced. The method comprises the steps of collecting data information of drivers and signal intersections, obtaining key factors influencing driving behaviors based on the collected data, forming a training sample set based on vehicle speed changes and the corresponding key factors, constructing a vehicle speed change and illuminance correlation prediction model, obtaining a trained prediction model by using the training sample set, and obtaining a driving behavior prediction result. And other key factor data except the illumination at the signalized intersection are collected and input into the correlation model, and the illumination when the vehicle speed change is minimum is selected as the optimal illumination at the signalized intersection. According to the method, the optimal illuminance of the signalized intersection is set according to the signalized intersection and the traffic environment data, and the driving safety is improved.

    本发明涉及一种信号交叉口照度设置方法,属于交通管理控制技术领域,解决了现有路灯照度按照固定值设置,不能适应不同信号交叉口以及不同交通环境,导致驾驶员在进出信号交叉口时车速变化较大,影响行车安全的问题。该方法包括:采集驾驶员以及信号交叉口处的数据信息,基于采集到的数据得到影响驾驶行为的关键因素,基于车速变化及对应的关键因素形成训练样本集,构建车速变化与照度关联预测模型并利用训练样本集得到训练好的预测模型,采集信号交叉口除照度外的其它关键因素数据输入到关联模型中,选取车速变化最小时的照度作为信号交叉口的最优照度。该方法根据信号交叉口以及交通环境数据设置信号交叉口的最优照度,提高了行车的安全性。
