Embodiment Construction

[0017] Such as figure 1 As shown, firstly, the analysis of the safety impact of the intersection is established, and the evaluation index system is established on this basis. Then, considering the traffic characteristics of trucks, the matter-element model for the safety evaluation of trucks at intersections is established by using the theory of extension set and correlation function. Finally, Through the calculation of the comprehensive correlation degree, a comprehensive evaluation of the operation safety of trucks at urban road intersections is made, and the evaluation index system, matter-element model and correlation weight coefficient are revised according to the actual implementation effect of the case.

[0018] Such as figure 2 As shown, it is a kind of evaluation index system diagram of truck intersection operation safety based on matter-element model. Within the scope of coordination, through the analysis of the safety factors of truck intersections, combined with t...

Abstract

The invention relates to a truck intersection running safety evaluation method based on a matter element model. The truck intersection running safety evaluation method comprises the steps of: firstlyanalyzing influence on safety of an intersection, and determining influencing factors for sustainable development levels of intersection truck traffic management; secondly, establishing a relevant evaluation system; establishing a matter element model for intersection truck safety evaluation by utilizing the matter element model, an extension set and a correlation function theory in extenics on the basis of considering truck traffic characteristics; and making comprehensive evaluation of truck running safety of urban road intersections through comprehensive correlation calculation. By analyzing relevant cases, the truck intersection running safety evaluation method can reflect the safety levels of trucks running at intersections exactly, and is an intersection safety evaluation method in line with China's road conditions.

Description

technical field [0001] The invention relates to the field of traffic safety evaluation of urban intersections, in particular to a method for evaluating the running safety of truck intersections based on a matter-element model. Background technique [0002] With the continuous growth of the number of trucks in our country, road safety problems in my country's cities frequently occur, and the number of deaths caused by truck accidents accounts for 48.23% of the death toll in traffic accidents. Blind spots and other factors lead to about 30% of traffic accidents in which large trucks scratch and crush pedestrians or non-motor vehicle drivers die when turning at intersections. Relevant studies have shown that when the traffic volume of trucks in the lane exceeds 20%, the intersection delay and traffic capacity decrease, and at the same time, the safety of the intersection also decreases. Therefore, the research on the evaluation of the operational safety status of truck intersec...
