Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0037] Such as figure 1 Shown: in order to be able to be used for the influence that the real-time change of vehicle of dealing with crossing is to the influence of direction release selection, improve the traffic efficiency of crossing vehicle, adaptive control method of the present invention comprises the following steps:

[0038] Step 1. Select M release cycles as the reference standard, wherein the release mode of each cycle is the same, and determine the transition release time of each trend according to the selected reference standard;

[0039] Specifically, M can be 3, that is, according to the selected 3 release cycles, the release situation of the next three cycles is predicted. The specific method of determining the transition release time of each movement is well known to those skilled in the art, and will not be repeated here.

[0040] Step 2, usi...

Abstract

The invention relates to a self-adaptive control method based on a video flow detector, which comprises the following steps: step 1, selecting M release periods as reference standards, enabling release modes of the periods to be the same, and determining transition release time of each moving direction according to the selected reference standards; step 2, counting the release duration of each moving direction of the selected reference standards by using a video flow detector to obtain the average release duration of each moving direction; and step 3, judging a release phase according to the transition release time of each moving direction in the step 1 and the average release duration of each moving direction in the step 2, so as to obtain the release states of the M release periods afterprediction. The method can be used for coping with the influence of the real-time change of the intersection vehicles on the direction release selection, and the intersection vehicle passing efficiency is improved.

Description

technical field [0001] The invention relates to an adaptive control method, in particular to an adaptive control method based on a video traffic detector, and belongs to the technical field of intelligent transportation. Background technique [0002] Traffic lights are an important display tool in traffic safety products. Its effective release can strengthen the management of vehicles at intersections, improve the utilization of road resources, reduce the waiting time of vehicles, and more importantly, stimulate the rapid development of the economy. In recent years, the optimization service engineering for road traffic clearance has gradually become an important field of research, and higher requirements have been put forward for the precision of traffic flow data, real-time monitoring of traffic flow status, and predictive release of selected schemes. Among them, the application of checkpoint big data technology has entered the field of vision of researchers, and how to max...
