Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Such as figure 1 As shown, an optimal traffic light design method based on intersection video resources includes the following steps:

[0029] Install camera devices at each intersection to obtain video at each intersection;

[0030] S1. Configure an independent virtual coil for identifying vehicle traffic volume for each lane, and obtain vehicle traffic volume in each direction;

[0031] Specifically, the virtual coil is to shoot the driving vehicle ...

Abstract

The invention belongs to the technical field of intelligent transportation of safe city and smart city projects, and in particular relates to a design method of an optimal traffic light based on intersection video resources. The present invention installs camera devices at each crossing, acquires video resources at each crossing, configures an independent virtual coil for identifying vehicle traffic volume for each lane, obtains vehicle traffic volume in each direction, and according to the vehicle traffic volume in each direction, The traffic data matrix is ​​established in two dimensions of time and traffic direction, and the traffic data matrix is ​​compressed in the time dimension to obtain the total traffic vector in each direction. Using the traffic intersection video, the vehicle traffic data is extracted, and the vehicle traffic in each direction is based on On the other hand, using an algorithm to analyze the optimal traffic light control method at the crossing, the present invention greatly improves the vehicle traffic efficiency and relieves the pressure of urban road congestion.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation of safe city and smart city projects, and in particular relates to a design method of an optimal traffic light based on intersection video resources. Background technique [0002] With the construction of Ping An China in full swing, cameras are almost everywhere in every major city. Facing the ever-increasing mass video resources, how to fully exploit its potential value and provide reference for urban management has been put on the agenda. [0003] In recent years, with the rapid increase of urban vehicles, the pressure on urban road traffic has been greatly increased, and the problem of ensuring smooth traffic has followed. The existing technology usually sets traffic lights artificially, which not only wastes manpower and material resources, but also lead to urban road congestion. Contents of the invention [0004] In order to overcome the deficiencies of the prior art a...
