Left-turn violation detection system at vehicle intersection

Abstract

The invention provides a left-turn violation detection system at a vehicle intersection. The intersection has an intersection stop line and a road yellow line and comprises a plurality of annular coils that are embedded on roads and parallel to each other for inducing the triggering state of vehicles, a processing module for receiving the triggering state and determining whether the vehicle violates the regulation or not according to the triggering state, and a camera for photographing images. The annular coils provided by the invention have reasonable width and space from small to big. The vehicles are not neglected with a plurality of driving lines available for violated left-turn vehicles, and interference is filtered by a logical algorithm, thereby photographing by mistake caused by triggering coils by vehicles in normal traffic and vehicles from other directions can be avoided.

Description

technical field [0001] The invention relates to a detection system for road traffic violations, and in particular to a detection system for vehicle crossing left-turn violations. Background technique [0002] In today's society, the city is developing very rapidly, the population and vehicles in the city are increasing rapidly, the traffic flow is increasing day by day, the traffic congestion is becoming more and more serious, the traffic system is facing huge pressure, and the traffic problem has become a major problem in urban management. It hinders the development of the city, especially the occurrence of various vehicle violations anytime and anywhere, which makes the monitoring of urban traffic very difficult. As a result, there is a specific situation in which vehicle violation capture technology is used to obtain illegal vehicles. [0003] With the increasing popularization and rapid development of applications of intelligent transportation systems in my country, the ...

Problems solved by technology

For vehicle left-turn violations at intersections where vehicles are prohibited from turning left, the general detection and capture method has the following problems: First, due to the large area where vehicles turn left, it is easy to miss the vehicle and the induction coil is not triggered; second, other traffic directions The vehicle triggers the induction coil, which will cause false shots; third, because the area where the vehicle turns left is very large, more cameras are needed to meet the large-scale capture area
