Embodiment Construction

[0078] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0079] The present invention includes three main contents: first, construction of evaluation index system and establishment of evaluation grade; second, design of scale corresponding to evaluation index; third, establishment of fuzzy evaluation method for traffic behavior safety. The specific process can be found in the attached figure 1 .

[0080] 1. Construction of evaluation index system

[0081] (1) Construction of evaluation indicators

[0082] Based on the traffic behavior "before-during-after" behavior process, the present invention conducts multi-angle and multi-angle analysis on the influencing factors of the traffic behavior process from the aspects of basic characteristic information of traffic participants, traffic safety awareness, traffic behavior characteristics and post-event attitude characteristics, etc. Hierarchical analysi...

Abstract

The invention discloses a traffic participant behavior safety assessment method, which can determine the safety level of behaviors according to the basic information of traffic participants and traffic behavior data. The method comprises the following steps of: firstly, establishing a traffic behavior safety assessment index system according to the behavior process of 'pre-event, amid-event and post-event' of the traffic behaviors and according to the principle of two-layer index systems; then determining each safety level of the traffic participants and a standard value of each level assessment factor by comprehensive assessment; designing an assessment index corresponding scale, and acquiring sample data; and finally, based on the research of 'traffic participants, traffic safety assessment indexes and traffic behavior requirements', determining a fuzzy measure model and a fuzzy integral assessment model by using the fuzzy measure theory aiming at an assessment sample structure assessment function, establishing a traffic behavior safety assessment method, and finally obtaining the safety level of the assessed sample by fuzzy identification.

Description

technical field [0001] The invention relates to a safety evaluation method, in particular to a traffic behavior safety evaluation method of traffic participants. Background technique [0002] Traffic safety is an important issue in urban traffic. In recent years, due to the substantial increase in the number of vehicles owned, the number of traffic safety accidents has also continued to rise. [0003] A traffic accident is an accidental event in the road traffic system due to the coordination imbalance of various elements such as people, vehicles, roads, and the environment. In the road traffic system, human is the only independent variable among the four elements, therefore, human is the core of traffic accidents. Statistics on traffic accidents at home and abroad show that 80% to 90% of traffic accidents are caused by human factors. Including the driver's operation error, carelessness or illegal driving, etc., also includes pedestrians and non-motor vehicles not obeying...
