Abstract

The invention relates to a multi-lane free flow video vehicle position and control method, the processes thereof are that: step 1, virtual coils are arranged in the visual field of a panoramic camera to form a detection area. Step 2, when a vehicle enters the detection area, a video detector starts an algorithm program to obtain the position of the vehicle. Step 3, a central processing unit starts a microwave communication system and an image snapshot system. Step 4, a logical comparison system judges whether the vehicle has electronic label information, if without, executing step 8. Step 5, the logical comparison system judges whether a vehicle license plate number in the electronic label information and the vehicle license plate number which is identified by a license plate recognition system are consistent, if not consistent, executing step 8 is. Step 6, the images of the vehicle which are snapshot are deleted. Step 7, toll transaction is done, and a transaction record is formed after the transaction. Step 8, the transaction record which is transferred to a background billing system is further treated. Step 9, returning to a main process. The method can achieve an electronic toll collection function in a multi-lane free flow mode through the accurate location for the vehicle and the coordination control for a system.

Description

technical field

[0001] The invention belongs to the technical field of intelligent transportation, and relates to a video vehicle positioning and coordinated control method of a free-flow electronic toll collection system, which can complete electronic toll collection in a free-running state of the vehicle. Background technique

[0002] With the continuous expansion of the city scale, the rapid development of expressways, the rapid growth of urban traffic flow, and the substantial increase in traffic density, new requirements have been put forward for the vehicle capacity of road toll stations.

[0003] The traditional manual and semi-automatic charging method must be "parking-paying-starting", and vehicle congestion often occurs. At present, the ETC electronic non-stop toll collection system adopted in China still needs to have toll booths and automatic railings. When vehicles pass through toll booths, they must drive along a certain lane, and the traffic capacity of vehicl...
