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.
