Traffic flow statistical method and system based on ambiguity path recognition system

The invention provides a traffic flow statistical method and system based on an ambiguity path recognition system. The method includes the steps that an RSU sends beacon site information to an OBU, the RSU receives vehicle information which is fed back by the OBU after the OBU receives the beacon site information, the number of current vehicles is added by one each time the RSU receives a piece of vehicle information, the number of the current vehicles serves as the number of the current vehicles after being added by one, and the RSU calculates the traffic flow in a current preset duration according to the number of the current vehicles, wherein the OBU comprise an OBU power supply. Therefore, the statistics cost is reduced, the problem of difficult reading is solved, accuracy of the statistical result of the traffic flow is improved, and energy consumption is lowered.
