Traffic management method based on vehicle-to-infrastructure integration technology

A traffic management method based on vehicle-to-infrastructure integration technology comprises the following steps of S1, acquiring motion data of all vehicles which are connected with a road-side unit in a vehicle-to-infrastructure technology (V2I) communication mode; S2, detecting whether an abnormal event occurs, and determining the type of the abnormal event; S3, when the abnormal event is a traffic accident, executing a step S4; S4, extracting the position and the speed of all vehicles in a traffic accident range in a preset time period; S5, calculating an average vehicle speed V in the traffic accident range; S6, comparing for determining whether the average vehicle speed V is smaller than a preset least vehicle speed V_min, if yes, performing a step S18, and otherwise, performing a step S7; ....; and S12, calculating the number sumi of queuing vehicles of each lane behind a first parking line and sequencing the numbers sumi from highest to lowest, and dynamically distributing passing time length of each lane according to the sumi. The traffic management method has beneficial effects of high traffic management efficiency, no manpower resource consumption and low danger coefficient. The traffic management method has functions of dynamically distributing lanes for the vehicles, improving traffic operation efficiency, performing ordered control on the vehicles at a crossing, and effectively reducing traffic accident rate at the crossing.
