Signalized intersection traffic signal lamp and vehicle track control method

Abstract

The invention relates to the field of intelligent networked automobiles, in particular to a rolling optimization method for signal intersection traffic signal lamp and vehicle trajectory control, andeach time interval comprises the following optimization steps: acquiring vehicle information in a target area; solving the mixed integer linear programming model by using the vehicle information in the target area to obtain the signal lamp state and the intersection arrival time of the vehicle; solving the motorcade head vehicle trajectory optimal control model by using the moment when the vehiclearrives at the intersection to obtain a motorcade head vehicle trajectory, and solving the motorcade following vehicle optimal control model by using the moment when the vehicle arrives at the intersection to obtain a motorcade following vehicle trajectory; achieving vehicle track control through the head vehicle track and the following vehicle track of the motorcade, and achieving traffic signallamp control through the signal lamp state. Compared with the prior art, the vehicle track and the traffic signal lamp at the signalized intersection are optimized at the same time, so that the signal lamp and the vehicle track are controlled more accurately.

Description

technical field [0001] The invention relates to the field of intelligent networked vehicles, in particular to a traffic signal light at a signalized intersection and a vehicle trajectory control method. Background technique [0002] With the increase of traffic demand, traffic congestion has gradually developed into a world-class problem in recent years, causing serious environmental problems and economic losses. In urban transportation networks, intersections are generally considered to be bottlenecks in traffic flow. So improving traffic signals at intersections can have a significant impact on the efficiency of urban transport systems. [0003] In recent years, with the development of intelligent network technology, vehicle-to-vehicle communication (V2V) and vehicle-to-road communication (V2I) have provided new data sources for traffic control. Governance offers new solutions. The current traffic control methods focus on signal light control, and there are few studies ...
