Aiming at the state of high-level intelligentization of traffic, some researchers have proposed to optimize the signal control scheme based on real-time information of vehicles, or implement the principle of "first come, first served" at intersections. The advantage of the state, or does not take into account the optimization needs of the system

Embodiment Construction
[0044] The following is based on Figure 1 to Figure 7 The specific embodiment of the present invention is further described:
[0045] Intelligent traffic control method at intersections where one-way traffic roads intersect in the environment of vehicle-road coordination and automatic driving. Specific steps are as follows:
[0046] Step 1: Define basic parameters:
[0047] Vehicle length: 4.8m; Vehicle width: 1.9m; Vehicle speed v max : 40km / h; Acceleration a: 8m / s 2 ;Minimum headway in the same direction: t 1 =1.18s; the minimum headway in the opposite direction: t 2 = 0.6s; road width = 3.5m.
[0048] When the vehicle is generated, the speed is v max =40km / h, the acceleration a is constant at 8m / s when the vehicle is moving at variable speed 2 .
[0049] The minimum headway in the same direction indicates the minimum time interval between the front ends of two consecutive vehicles passing through a certain section in the vehicle queue traveling on the same lane....

The invention discloses a one-way traffic road intersection traffic control method in an automatic driving environment, and the method comprises the steps: building a determined region by taking the center of an intersection as the center of the determined region; acquiring vehicle position information and vehicle running state information entering the system in real time; and determining a firstgroup of conflicting vehicles, calculating system total residence time corresponding to the two alternative schemes, and selecting the alternative scheme with the minimum system total residence time.According to the method, vehicle-road cooperation and automatic driving are taken as technical backgrounds, intersection traffic control of one-way traffic road intersection is taken as a research object, the total residence time of vehicles in a system is considered, and a two-one-way road intersection traffic control strategy considering system requirements and system advantages is provided.
Description
technical field [0001] The invention relates to the field of signal control in traffic management. With the background of vehicle-road coordination and automatic driving, it automatically determines the vehicle traffic control scheme when two one-way traffic roads intersect, belongs to the field of intelligent transportation, and is specifically a vehicle-road coordination and An intelligent traffic control method at one-way road intersection intersections in an automatic driving environment, referred to as a traffic control method at one-way road intersections in an automatic driving environment. Background technique [0002] Vehicle-road coordination and automatic driving are two inevitable trends in the development of transportation. Under this trend, information can be shared between vehicles and roads and between vehicles. The driving of vehicles mainly depends on the commands of the vehicle control center, which belongs to the high-level traffic intelligent state. At ...
