Non-signalized crossing optimization control method and system in cooperative vehicle infrastructure environment

The embodiment of the invention provides a non-signalized crossing optimization control method and system in cooperative vehicle infrastructure environment. The method comprises the following steps that roadside equipment sends driving state information sent by each vehicle-mounted unit to roadside management equipment; the roadside management equipment calculates road right information and vehicle speed guide information of each vehicle by using a preset crossing signal optimization model according to the driving state information of each vehicle passing through a crossing, in addition, the road right information and the vehicle speed guide information are sent to the roadside equipment, and the roadside equipment sends the road right information and the vehicle speed guide information to corresponding vehicles. The method and the system provided by the embodiment of the invention have the advantages that the road right information and the vehicle speed guide information of each vehicle are calculated according to the preset crossing signal optimization model and the optimized green light time based on a sliding time window T, the real-time interactive guide control with vehicle individuals is realized, and the vehicles at the crossing are subjected to speed optimization guide, so that the intelligent traffic control efficiency of the crossing is improved.
