Calculation of danger level of pedestrian crossings

Abstract

The present article is devoted to description of some major factors influencing the danger of a pedestrian crossings zone. The review of the factors affecting the number of «vehicles-pedestrians» conflicts in the pedestrian crossing zone was performed. An example of the developed program for determining the danger level of pedestrian crossings on the main streets was given. Keywords-a pedestrian crossing; danger level; width of a pedestrian crossing; road signs; a program for calculation of the danger level of pedestrian crossings.

Social Force Model-Based Safety Evaluation of Intersections in Arterials Considering the Pedestrian Yield Rule

“…The intersection safety evaluation method based on traffic conflict technology can reflect the operation status of the actual traffic flow effectively and combined with the status of the operation of the intersection evaluation can be a good way to prevent the occurrence of traffic accidents. After summarizing the relevant research [7][8][9][10][11][12][13][14][15][16][17][18], it is found that the following four aspects can be further studied:…”

“…On the one hand, there are studies on the analysis and evaluation of various factors affecting the safety of participants at intersections, that quantify the severity of conflicts at intersections. For example, Porkhacheva, S. M [ 7 ] analyzed important factors affecting pedestrian crossing safety at the intersection, studied these factors, and proposed a method to evaluate the degree of danger of crosswalks at the intersection. Kumar, A et al [ 8 ] determined the severity of conflict according to the demographics of pedestrians and their street-crossing behavior.…”

After summarizing the relevant research [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], it is found that the following four aspects can be further studied: Basic indicators cannot completely demonstrate the intersection operation safety considering pedestrian yield rules, such as TTC, PET, etc. When pedestrians and motor vehicles collide, the corresponding perception is completely different, which is rarely considered in mainstream intersection safety evaluation studies.…”
