Intersection traffic flow adjusting method based on vehicle-road cooperation

Abstract

The invention discloses an intersection traffic flow adjusting method based on vehicle-road cooperation, and relates to the field of road traffic. The method comprises the following steps: determiningthe positions and the number of conflict points in an intersection according to the number of roads joined at the intersection, the number of specific lanes contained in each road and the lane widthof each road, and calculating the dangerous time period of each conflict point; a vehicle condition adjusting area is arranged on an entrance lane around the intersection. A sufficient number of sensors are installed around a road or under the road surface to monitor the real-time position, the real-time speed, the real-time acceleration and other parameters of each vehicle above the road and transmit the vehicle condition parameters to the information processing module in real time. The information processing module regulates and controls the vehicles in the vehicle condition regulation areaaccording to the real-time information of the vehicles above the surrounding roads in combination with the dangerous time periods of the conflict points in the intersection. Therefore, the vehicles can avoid the dangerous time periods of the conflict points and sequentially enter and pass through the intersection area according to a certain time interval.

Description

technical field [0001] The invention relates to the field of highway traffic, in particular to a method for regulating traffic flow at an intersection based on vehicle-road coordination. Background technique [0002] With the development of society, the number of cars has increased year by year, and a series of problems such as traffic disorder, traffic congestion, and frequent traffic accidents have become increasingly prominent. The intersection is located in the intersection of roads, and there are many traffic conflict points (conflict point refers to the intersection of two traffic flow trajectories in the intersection), which is the hardest hit area for traffic accidents and traffic congestion. The traffic capacity of the vehicle is restricted by the driver's reaction time, the coordination time between vehicles and other reasons, and it has been unable to fundamentally solve the above problems. [0003] Vehicle-road coordination is the use of advanced wireless commun...
