Problems solved by technology
[0002] Existing methods for judging low-speed vehicles on expressways mostly rely on external devices such as speedometers, camcorders, and controllers. The cost is high and the detection density is low, and the judgment is only for evidence collection and does not provide information on the vehicle. help

The present application discloses a method and system for judging the low-speed state of a vehicle on an expressway, including: judging the vehicle state after filtering the track data of the target vehicle; if the vehicle state is a low-speed state, determining the low-speed state of the target vehicle The location at the beginning, the highway and the start time of the state, and judge the road section where the vehicle is located; if the target vehicle is not a vehicle to be excluded, then determine the calculation around the target vehicle according to the location at the beginning of the state, the highway and the start time of the state The trajectory data of the vehicle; according to the calculated trajectory data of the vehicle, determine the comparison condition corresponding to the vehicle state; according to the target vehicle state and the corresponding comparison condition, judge the low-speed state of the target vehicle, and call the police. The implementation of the present application does not rely on external equipment, is low in cost, has strong real-time performance, can monitor vehicles in all ranges, helps drivers correct wrong behaviors, provides assistance to vehicles and drivers, and reduces potential safety hazards on high speeds.
Description
technical field [0001] The present application relates to the field of vehicle monitoring, in particular to a method and system for judging the low-speed state of a vehicle on an expressway. Background technique [0002] Existing methods for judging low-speed vehicles on expressways mostly rely on external devices such as speedometers, camcorders, and controllers. The cost is high and the detection density is low, and the judgment is only for evidence collection and does not provide information on the vehicle. help. [0003] To sum up, it is necessary to provide a method and system that does not rely on external devices, has low cost, high detection density, and can provide assistance to drivers. Contents of the invention [0004] In order to solve the above problems, the present application proposes a method and system for judging the low-speed state of a vehicle on an expressway. [0005] On the one hand, the present application proposes a method for judging the low-sp...
