The invention provides a highway traffic operation safety evaluation method and system, belongs to the technical field of highway traffic. Psychological and physiological indexes of a driver and corresponding vehicle operation parameters in a highway virtual traffic environment are obtained as virtual driving data by means of a traffic safety driving simulation system and a physiological and psychological test system. Different vehicle types are selected, and psychological and physiological indexes of a driver and corresponding vehicle operation parameters in the real traffic environment of the expressway are monitored in real time to serve as real vehicle test data; accident analysis is carried out on historical data of traffic accidents happening to the expressway within a period of time, and accident characteristics and accident causes are obtained; the virtual driving data, the real vehicle test data, the road traffic safety influence factors and the accident cause data are combined to determine a risk road section with dangers or potential safety hazards of the expressway; and highway traffic safety level evaluation is carried out on the risk road section, and highway improvement suggestions are determined according to an evaluation result.
Description
technical field [0001] The invention relates to the technical field of highway traffic, in particular to a method and system for evaluating the safety of expressway traffic operation. Background technique [0002] With the great development of my country's road transportation infrastructure construction, the road mileage and the number of motor vehicles have increased rapidly, which has enabled the rapid development of the road transportation industry and played a significant role in promoting the development of the national economy. But at the same time traffic accidents are also becoming more and more serious, especially the occurrence of mass casualties and serious traffic accidents often cause serious casualties and huge property losses, resulting in greater social impact. For expressways that have been opened to traffic, how to conduct operational safety evaluations under dynamic traffic conditions of people, vehicles, roads, and the environment, analyze potential risk ...
