Problems solved by technology

With the rapid development of society, the country's highway mileage has increased by leaps and bounds. In order to prevent accidents caused by excessive speed on the highway, road speed limit signs will be set up on each road section. However, due to various reasons, there are many unreasonable speed limit signs on road sections. For example, the speed limit of a highway is 120KM / H, and the speed limit of some road sections is suddenly 80KM / H, which brings confusion to drivers and poses safety hazards. At this time, it is necessary to find unreasonable speed limit signs and modify them.
[0003] At present, when looking for unreasonable speed limit signs, the traffic control department first needs to find a large number of staff, and through a large number of staff cloud to search one by one on the road sections that need to be checked, or to know the setting of unreasonable speed limits based on driver complaints and reports Signs, because the current investigation of unreasonable speed limit signs requires a lot of manpower and material resources, resulting in increased inspection costs for unreasonable speed limit signs and reduced work efficiency

Abstract

The invention discloses a method, device, storage medium and terminal for screening unreasonable speed limit signs. The method includes: determining the road section to be screened, and obtaining the vehicle trajectory corresponding to the road section to be screened; Divide the road segment to be screened into multiple road segments; calculate the average speed of vehicles on the road segment to be screened and the average speed of vehicles on multiple road segments based on vehicle trajectories; The average speed of vehicles on each road section is screened to determine the road section where the unreasonable speed limit sign is located. Therefore, by adopting the embodiment of the present application, by determining the screening road section and dividing the road section and obtaining the vehicle trajectory on the road section, and then calculating the average speed of the vehicle on the road and the average speed of each section of the vehicle to screen Check the road section where the unreasonable speed limit signs may exist, and further determine the unreasonable vehicle speed limit signs on the road, thereby improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of big data analysis, in particular to a screening method, device, storage medium and terminal for unreasonable speed limit signs. Background technique [0002] Highway traffic signs are graphic symbols that display traffic laws and road information. Among them, highway speed limit signs are a type of road traffic signs, which can remind drivers to drive at the speed limited by speed limit signs to ensure the safety of the driver's life and property. With the rapid development of society, the country's highway mileage has increased by leaps and bounds. In order to prevent accidents caused by excessive speed on the highway, road speed limit signs will be set up on each road section. However, due to various reasons, there are many unreasonable speed limit signs on road sections. For example, the speed limit of a highway is 120KM / H, and the speed limit of some road sections is suddenly 80KM / H, which brings conf...
