Embodiment Construction

[0076] Taking the intersection as an example, it is assumed that the east-west, north-south entrance and exit lanes are arranged symmetrically, with 6 lanes in both directions. Taking the east-west entrance as an example, the process of establishing the signal control scheme and signal timing parameters of the present invention is discussed in detail. North-south imports are determined in the same way as east-west imports.

[0077] Step 1. Obtain the vehicle traffic demand of each entrance and flow direction of the intersection in real time

[0078] At the end of all phase releases in the north-south direction, collect the number of vehicles queuing up in the left-turn traffic flow and through traffic flow at the east entrance, on the manned driving lane, mixed driving lane, and unmanned driving lane: 0, 30, 0, 26, 39, 0; In the left-turn traffic flow and through traffic flow at the west entrance, the number of vehicles parked and queued in the manned driveway, mixed driving ...

Abstract

The present invention relates to an intersection signal control parameter optimization method in a man-machine mixed driving environment. The optimization method comprises the following steps of 1, collecting vehicle traffic demand data of vehicles in each entrance and flowing direction of an intersection; 2, establishing the function of each lane; 3, setting signal phase schemes in a control system; and 4, setting corresponding timing parameters according to the different signal phase schemes. Compared with a conventional timing, inductive and self-adaptive signal control method, the method provided by the invention can more effectively improve the utilization efficiency of the time and space resources of the intersection, the intersection traffic capacity can be improved by 30% -40%, andthe delay is reduced by about 40% under the same traffic demand.

Description

technical field [0001] The invention belongs to the field of traffic engineering, and in particular relates to a method for optimizing control parameters of intersection signals in a human-machine mixed driving environment. Background technique [0002] With the gradual application and promotion of 5G communication technology around the world, as one of the important application scenarios - self-driving cars, more and more will appear on the road. Academician Li Deyi, chairman of the Chinese Association for Artificial Intelligence, pointed out: "The transformation of automobiles to autonomous driving is a gradual process, and for a long time to come, it will be a situation of human-machine hybrid driving." At the same time, foreign studies have shown that applying control, sensing, and communication technologies to road automation for road vehicles can improve road performance and increase road capacity by about 3 times. In the human-machine hybrid driving environment, cons...
