Abstract

The invention discloses a road risk assessment method and device, and relates to the technical field of traffic safety, mainly aiming to assess potential risks of traffic accidents on roads. Accordingto the main technical scheme of the invention, the road risk assessment method comprises the steps: obtaining an accident road where a traffic accident illegal behavior occurs in a preset time periodand a corresponding traffic accident illegal behavior data size from a traffic accident illegal behavior database; acquiring a dangerous driving behavior data volume corresponding to the accident road in the preset time period from a dangerous driving behavior database; obtaining a road risk assessment threshold according to the traffic accident illegal behavior data volume and the dangerous driving behavior data volume of the accident road; acquiring dangerous driving behavior data volume corresponding to other roads except the accident road in a preset time period from a dangerous driving behavior database; and comparing the dangerous driving behavior data volume corresponding to the other roads with the road risk assessment threshold to obtain risk assessment results of the other roads.
