Method and system for detecting vehicle congestion at toll station

Abstract

The invention discloses a system and method for detecting vehicle congestion at a toll station. The method comprises the steps of acquiring image data of an entering end of the toll station, and generating number data and vehicle length data of entered vehicles according to vehicle location and license plate location; acquiring number data and vehicle length data of exited vehicles through a toll lane ground sensing coil; generating the total length of open lanes of the toll station according to the number of pre-stored open lanes of the toll station and the length corresponding to each lane; generating the total length of the vehicles in a toll station square according to the number data and the vehicle length data of the entered vehicles and the number data and the vehicle length data of the exited vehicles; generating the congestion rate of the toll station square through dividing the total length of the vehicles in the toll station square by the total length of the open lanes of the toll station; and generating a detection result of vehicle congestion of the toll station according to the congestion rate. Through adopting the system and the method, the congestion degree of the toll station can be rapidly and accurately detected, so the vehicle passing efficiency and the service quality are improved and powerful support is provided for rapid passing of the vehicles.

Description

technical field [0001] The invention relates to the detection technology of toll stations on expressways, in particular to the detection technology of vehicle congestion and queuing at expressway toll stations, specifically a method and system for detecting vehicle congestion at toll stations, which provide strong support for the rapid passage of vehicles. Background technique [0002] At present, some expressway toll stations have very serious queuing congestion, which has caused great dissatisfaction among users on expressways. In order to solve the problem of high-speed congestion, some existing toll stations stipulate that if the queue exceeds the specified length, or the number of vehicles in the queue exceeds the specified number of vehicles, it needs to be released for free, so as to improve the traffic efficiency of the toll station. [0003] Due to the large differences in the scenes of the toll plaza and the toll rolling track, there is currently no detection metho...
