Problems solved by technology

At present, the evaluation of the traffic safety of pedestrian facilities at intersections is also evaluated from the impact of pedestrian-vehicle conflict, but the application of the mechanism of pedestrian-vehicle conflict to the safety performance evaluation of pedestrian crossings in unsignalized sections is still in its infancy, and there are few related studies

Embodiment Construction

[0041] In order to further describe the technical features and effects of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 1 As shown, the present invention provides a kind of method for evaluating the safety performance of pedestrian crossings adapting to the condition of no-signal control section, which comprises the steps:

[0043] Step 1: Determine the probability index of accidents; the number of encounters between people and vehicles on the road section is positively correlated with the probability of conflicts, and the potential number of encounters between people and vehicles on the road section can be used as the probability index of accidents. Based on the traffic conflict theory, the potential traffic conflict possibility is used to predict the number of actual conflicts between pedestrians and vehicles.

[0044] For a single pedestrian crossi...

Abstract

The invention discloses a pedestrian crossing safety performance evaluation method adapting to a condition of a non-signal control road section. The method comprises the following steps: 1) determining an accident occurrence probability index; 2) determining severity indexes of an accident; 3) according to the step 1) and the step 2), obtaining a pedestrian crossing safety performance evaluation value of the non-signal control road section; and 4) grading the safety performance evaluation values of the non-signal control road section pedestrian crossings to obtain an evaluation result of the safety performance of the non-signal control road section pedestrian crossings. According to the evaluation method provided by the invention, the evaluation time period can be shortened, the signal-control-free road section pedestrian crosswalk with poor safety performance can be quickly identified, corresponding improvement measures are further provided, and the pedestrian crossing safety at the signal-control-free road section pedestrian crosswalk is ensured.

Description

technical field [0001] The invention relates to a method for evaluating the safety performance of a crosswalk adapted to the condition of a road section without signal control, and belongs to the fields of road traffic management and traffic safety. Background technique [0002] Pedestrians do not have an independent right of way when crossing the road without signal control, which makes conflicts between pedestrians and vehicles frequently occur, making it difficult to guarantee crossing safety, resulting in frequent pedestrian accidents, which not only brings huge economic losses, but also runs counter to the people-oriented concept. Therefore, it is necessary to deeply study the safety performance of pedestrian crossings on roads without signal control. [0003] At present, domestic and foreign researches on pedestrian crossing safety on unsignalized road sections mainly focus on the characteristics of pedestrian crossing, the factors affecting risk behavior of crossing t...
