行人过街人车冲突等级评价及影响分析

无信号控制路段人车冲突等级的划分对于采取交通安全策略有重要意义，本文采用交通调查和数据分析的方法探索人车冲突严重程度的影响因素.通过视频采集确定了综合人、车、路 3方面特性的 14个解释变量，通过变量间相关性分析对解释变量进行筛选，再建立基于Odered Probit回归分析的人车冲突量化模型确定了影响显著的因素.

Evaluation and Impact Analysis of Pedestrian-vehicle Conflict Severity

The classification of conflict grade of pedestrians and vehicles at uncontrolled mid-block crosswalk is of great significance for the adoption of traffic safety strategies. This paper explored the influencing factors of the severity of pedestrian- vehicle conflict by means of traffic investigation and data analysis. Fourteen explanatory variables are identified by video capture, which integrates the three characteristics of human, vehicle and road. The explanatory variables are screened by correlation analysis between variables. Then a quantitative model of humanvehicle conflict based on Odered Probit regression analysis is established to determine the significant factors.
