A traffic management method based on vehicle-road coordination technology

Abstract

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.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a traffic management method based on vehicle-road coordination technology. Background technique [0002] The Internet of Vehicles is through the Internet technology, all vehicles can transmit various information of themselves to the central processing unit. Through computer technology, the information of these large numbers of vehicles can be analyzed and processed to calculate the best routes for different vehicles, issue reports on road conditions and adjust signal light cycles. [0003] The Internet of Vehicles includes the interconnection of vehicles to vehicles (V2V), vehicles to roads (V2I, Vehicle to Infrastructure), vehicles to people (V2P), vehicles to centers (V2C), etc., to realize vehicle ad hoc networks and various heterogeneous networks The communication and roaming among them ensure real-time performance, serviceability and network ubiquity in terms of function...
