Test and evaluation method of latent risk perception ability of driver

Abstract

The invention relates to a test and evaluation method of the latent risk perception ability of a driver, and belongs to the technical field of road traffic safety. The method mainly comprises the following steps: (1) classifying latent risk information; (2) determining risk levels of different types of latent risk information; (3) determining a latent risk degree of the latent risk information in a test road section or region; (4) determining a driving risk degree under the latent risk information in the test road section or region based on the latent risk degree; (5) constructing a virtual experiment test scene for testing the latent risk perception of the driver; (6) testing latent risk perception data of the driver through a driving simulation experiment; (7) evaluating the latent risk information perception of the driver. The method can test and evaluate the latent risk perception ability of the driver and assist in realizing the assessment of the latent risk perception ability of the driver, so that the risk cognition ability of the driver is improved, the safety awareness of the driver is enhanced, and the possibility of accident occurrence is reduced.

Description

technical field [0001] The invention relates to a test and evaluation method for a driver's latent risk perception ability, which belongs to the technical field of road traffic safety. Background technique [0002] As long as a vehicle is driven, there are safety risks. Among the various safety risks encountered by vehicle driving, there is one risk that is most likely to be overlooked, that is, the risk caused by the road traffic environment. This risk is actually produced by road conditions or environmental factors that are not conducive to safe driving. Since this risk is different from various traffic highlights, it is only a possible risk to driving safety, so it is called latent risk. . In fact, the vast majority of traffic accidents come from the outbreak of latent risks. From a macro point of view, road traffic potential risk factors are one of the main factors affecting traffic safety. [0003] Traffic safety involves many factors such as people, vehicles, roads...

AI Technical Summary

Problems solved by technology

At present, there is no mature system that can be directly used to test and evaluate the driving potential risk. Therefore, it is necessary to develop a related technology and method that has more comprehensive functions and can realize the testing and evaluation of the driving potential risk. To help provide drivers with risk awareness, thereby improving the safety of vehicle driving and reducing the possibility of accidents
