A device for detecting reversing behavior and its detection method

Abstract

The invention provides a device for detecting a back-up action. The device comprises an induction coil which is connected with a detecting device arranged on the road side in front of the induction coil. A detecting method of the device includes the following steps: (1) when a vehicle passes through the induction coil arranged on an expressway fork, the detecting device detects signals; (2) the detecting device transmits the signals to a microprocessor, the microprocessor memorizes current time, triggering equipment of a vehicle license plate recognition device receives the signals of the detecting device and transmits the signals to the microprocessor, and the signals are saved in a memorizer; (3) time T1 of a first passing vehicle serves as a standard, time of following passing vehicles is set to be Ti, wherein i equals to two, three and the like, if difference of 4-6 minutes exists between the Ti and the T1, license plate information of the first vehicle and license plate information of the following time Ti are compared, if the license plate information is judged to be the same, the result shows that the vehicle carries out the back up at the fork, the information is sent to the traffic administration department, or else the information of the vehicle is deleted; and (4) time T2 of a second passing vehicle serves as the standard, and the process is repeated.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and is a device for detecting the reversing behavior of a vehicle at a fork in an expressway, in particular to a device for detecting the reversing behavior of a vehicle at a fork in an expressway and a detection method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, more and more cars have entered the families of ordinary people. The huge number of cars has made traffic problems a difficult problem that a city or even a country has to face. With the development of intelligent transportation technology, modern transportation has realized many automatic monitoring and control. In particular, the monitoring of some traffic violations has been greatly developed, including the use of electronic eyes to capture some behaviors such as running red lights, retrograde and illegal left turns at crossr...

AI Technical Summary

Problems solved by technology

At present, the automatic detection of reversing behavior on the expressway is still blank, especially for the bifurcation intersection of the expressway, which is a frequent location for car owners to reversing. The reversing behavior at the bifurcation intersection will not only cause traffic jams, but may also cause traffic jams ACCIDENT
