Problems solved by technology

The main disadvantage of this type of method is that it relies too much on the prior threshold and cannot accurately distinguish various states of road synchronous flow and congestion; at the same time, this method cannot make short-term predictions of the traffic state at the intersection of the detection point
In addition, the induction coil wears out and the installation and maintenance costs are higher compared to video capture technology

Abstract

The invention discloses a road condition identifier based on a license plate recognition technology and an identification method thereof. The identifier mainly comprises a front-end video capture device, an automatic license plate identifier, a vehicle detection device and a multifunctional repair state identification module. The intelligent control of traffic lights is realized finally through collecting traffic parameter data and combining massive historical traffic data. The invention can realize the short-term traffic forecast, detection of special traffic incidents and dynamic control of traffic signals according to the current traffic state, and has the advantages of simple installation and convenient use.

Description

technical field [0001] The invention relates to the field of computer application technology and intelligent traffic control, in particular to a road traffic state judging device and a road traffic state judging method based on accurate license plate recognition technology. Background technique [0002] Road traffic status includes two categories: normal status and abnormal status. Abnormal traffic conditions can be divided into regular traffic congestion and traffic incidents. The purpose of traffic state evaluation is to use certain methods to analyze real-time traffic data, quickly identify various abnormal traffic states, and provide a basis for traffic control. [0003] The discrimination methods of traffic jams and traffic events can be divided into two categories: manual discrimination methods and automatic discrimination methods. The former includes citizen reports, specialist reports and closed-circuit television surveillance. The advantage of this method is that...
