Drivers’ Peripheral Risk Perception Evaluation Indexes and Threshold Division

Abstract

First, the importance of drivers’ peripheral risk perception ability to traffic safety is discussed. Second, the detection of peripheral risk perception ability is put forward and its evaluation indexes are established. Third, 1,325 drivers are tested using the peripheral risk perception detector and the tested accident records of drivers in past three years are investigated. Through analysis of the test data, the objective existence of accident—prone drivers is verified, the effectiveness of the peripheral risk perception detector and the rationality of the evaluation indexes are proven, and the threshold of the peripheral risk perception indexes is identified. Results show that drivers’ peripheral risk perception has a significant impact on traffic safety, and that the detection of peripheral risk perception ability can identify and screen out accident—prone drivers.
