The invention discloses an expressway mixed heterogeneous traffic flow rainy day variable speed limit control system and method, and relates to the technical field of expressway management control. Comprising a control module, a data acquisition module and an intelligent network connection vehicle, the current weather condition and the traffic state can be clearly known through acquisition of various devices of the data acquisition module, and prediction of the running state risk is realized from multi-angle consideration, so that whether speed control is performed or not is judged. In the management and control process, the relation between the rainfall condition and the vehicle parameters is established, the accuracy of the vehicle speed limit value is improved, and the speed of the vehicle is effectively controlled in the rainfall weather. The method is applied to the mixed heterogeneous traffic state of the intelligent network connection vehicle and the manual driving vehicle, different speed limiting information channels can be provided for the manual driving vehicle and the intelligent network connection vehicle, and safe driving and driving efficiency of different types of vehicles under the complex traffic condition are effectively guaranteed.

    本发明公开了一种高速公路混合异质交通流雨天可变限速控制系统及方法,涉及高速公路管理控制技术领域。包括:控制模块、数据采集模块和智能网联车,通过数据采集模块各种设备的采集,能够清楚的得知当前的天气状况以及交通状态,从多角度考虑实现运行状态风险的预测,从而判断是否进行速度管控。在管控过程中,建立降雨状况与车辆参数的关系,提高车辆限速值的准确性,使得降雨天气下对车辆的速度进行有效的控制。本发明应用于智能网联车辆与人工驾驶车辆的混合异质交通状态,能够针对人工驾驶车辆和智能网联车辆分别提供不同的限速信息渠道,有效的保障了复杂交通状况下不同类型车辆的安全驾驶和行车效率。
