Array radar based intersection running state evaluation method

Abstract

The invention provides array radar based intersection running state evaluation method, and mainly relates to the field of acquisition and evaluation of intersection traffic information. By means of the method, real-time evaluation of the intersection running state is realized through comprehensive application of novel array radar vehicle detection equipment. The method adopts a two-dimensional active array radar technology, so that large-area and large-range road traffic information detection can be realized, instant positions and instant speeds of multiple targets can be detected accurately, the queuing length, various traffic incidents such as running in a wrong direction and the like can be detected, the problems of vehicle plate covering as well as detection missing or repeated detection for park and the like is solved, and more comprehensive data and updating as well as wider application are brought to traffic information acquisition; and further, automatic judging accuracy for the intersection traffic running state is improved, real-time decision and emergency treatment information are provided for traffic management, traffic accidents are reduced, and the service level for the intersection is increased.

Description

technical field [0001] The invention relates to the technical field of collection and evaluation of intersection traffic information, in particular to an evaluation method for an intersection operating state based on display radar. Background technique [0002] The continuous increase in car ownership has led to increasingly frequent traffic congestion and accidents, especially the more serious traffic environment at intersections. If the traffic police cannot obtain information on intersection incidents as soon as possible, they will not be able to carry out rescue work in time, which will cause road congestion to spread. Reduced road operation efficiency, brought huge economic and property losses. [0003] Traffic status detection technology is a technology that installs collection equipment on roads that are complex or prone to congestion, detects the number, speed, and queue length of passing cars, and processes the collected information through a wired or wireless netwo...

AI Technical Summary

Problems solved by technology

The traditional model algorithm is too blunt to classify the traffic state by setting the threshold according to the change of a certain traffic parameter, which will cause the system to misjudge the state; at the same time, the disadvantage of the traditional detector is that it can collect information on the breakpoint road surface and cannot Obtain the complete traffic status of a long section, and there is a phenomenon of misjudgment of traffic events in blind spots
