[0003] In view of the current off-site law enforcement status, this invention proposes a traffic violation detection method and system based on vehicle passing or positioning data fusion, the purpose is to make full use of the existing road vehicle driving data, through the association of multi-source data, intelligent Detect illegal driving behaviors such as vehicles not driving in the guiding lane, illegally occupying the road, etc., and realize off-site traffic violation detection; the method of the present invention does not need to rely on complex image processing algorithms, and has no high impact on the electronic police equipment installed on the road. Hardware requirements, only basic passing vehicle detection and number plate recognition functions are required to meet the needs of off-site law enforcement detection, and solve the current problem of law enforcement detection of illegal occupancy in the entire road network that cannot be realized due to cost constraints

Embodiment
[0031] The method for detecting traffic violations based on data fusion in the embodiment uses the passing data detected by checkpoint equipment in the road network and the real-time positioning data of operating vehicles such as taxis as the supporting data, and processes and compares the two types of passing data respectively. Analyze and obtain the driving path of the vehicle, and further, integrate the driving path with the electronic police passing data at the intersection to analyze and identify the vehicle's lane-occupying behavior; figure 1 , the detailed steps are:
[0032] S1. Take the entrance lane of the signalized intersection as the detection unit, and obtain the lane passing data according to the electronic police detection data corresponding to each lane, including lane turning, passing time, and license plate number.
[0033] S2. Determine the downstream adjacent intersection and road section corresponding to each turning lane of the intersection entrance road...

The invention provides a data fusion-based traffic violation detection method and system. Electronic police detection data of a vehicle at a road crossing, data of the vehicle at other checkpoints and vehicle positioning data are subjected to fusion analysis; law violation phenomena that the vehicle does not run in a directive lane at the crossing and the vehicle illegally occupies a lane are further detected; off-site law enforcement based on data analysis can be realized; based on the method, the data fusion-based traffic violation detection system put forward in the invention can be used for obtaining vehicle running data from a checkpoint detection system and an operating vehicle supervision system for taxis and the like, and running routes of the vehicle can be analyzed; law violation detection, law violation data generation, law violation verification and law violation handling can be further realized. The method and system have low requirements for electronic police hardware and can be widely applied to urban road network traffic violation management, and reliable off-site law enforcement and detection means can be provided for traffic police departments.
Description
technical field [0001] The invention relates to a method and system for detecting traffic violations based on data fusion. Background technique [0002] With the rapid increase of road traffic volume and frequent incidents of vehicle violations, traffic management departments are faced with increasingly heavy traffic supervision and law enforcement tasks. In order to effectively control illegal behaviors that do not follow regulations, intelligent off-site law enforcement such as electronic police The system has been promoted and applied. The current electronic police system mainly detects and captures vehicles running red lights at intersections. For illegal intersection violations such as vehicles changing lanes illegally and not following the guide lane, it is based on the image processing technology contained in the electronic police equipment. Coils and other methods realize the microscopic detection of vehicle driving behavior and the identification of illegal behavio...
