Vehicle operation risk assessment system in multi-vehicle environment based on dynamic risk potential energy field

A dynamic risk potential energy field-based vehicle operation risk assessment system in a multi-vehicle environment relates to the technical field of road safety, and solves the problem of low assessment accuracy of an existing vehicle operation risk assessment method. The system comprises an information acquisition subsystem, a data extraction center and a dynamic risk potential energy field subsystem; the information acquisition subsystem is used for acquiring dynamic traffic information and transmitting the dynamic traffic information to the data extraction center connected with the dynamictraffic information; the data extraction center is used for classifying the dynamic traffic information transmitted by the information acquisition subsystem, and respectively establishing a target position data set, a static obstacle data set, a road condition data set and a dynamic obstacle data set; and the dynamic risk potential energy field subsystem is used for calculating dynamic risk potential energy field intensi
