Signal intersection control method based on main path, terminal and storage medium

Abstract

The invention discloses a signal intersection control method based on a main path, a terminal and a storage medium, and the method comprises the steps: obtaining vehicle trajectory data in a preset road network, and determining all main paths in the preset road network according to the vehicle trajectory data; obtaining path information of each main path, and judging whether each main path meets a main path optimization coordination condition or not according to the path information; and performing signal control optimization on the main path meeting the main path optimization coordination condition. According to the invention, on the basis of the vehicle trajectory data in the road network, coordination optimization control can be carried out on intersection signals of a large-flow main path meeting conditions in the road network, so that the problem that optimization control is only carried out on a batch of adjacent intersections of the same trunk road in a traditional signal coordination control mode is solved, and the passing efficiency of the whole road network is improved; meanwhile, the signal intersection coordination control theory and method are perfected, the urban traffic control level of China can be improved, and the traffic capacity and the operation quality of a road network are improved.

Description

technical field [0001] The present invention relates to the field of terminal applications, in particular to a signal intersection control method based on a main path, a terminal and a storage medium. Background technique [0002] Intersection is the bottleneck of urban road network, and its signal control effect directly determines the operation quality of urban traffic. The majority of traffic science and technology workers have done a lot of research to find the optimal control method of signalized intersection. Signal coordinated control (referred to as wire control or green wave) is an effective control method for a group of adjacent intersections on the road, which can greatly improve the traffic capacity and service level of the path. However, the traditional signal coordination control is only aimed at the intersection on the same arterial road, and lacks the identification of the control path, resulting in a discrepancy between the control path and the actual path o...
