摘要
为了提高两相位信号交叉口右转车辆与过街行人的通行安全,构建了基于多元有序Logistic模型的礼让意向模型以寻找影响右转车辆礼让行人意向的因素。在现有研究因素是否对右转车辆礼让行为产生影响的基础上,将右转车辆的礼让方式进一步细分为“软礼让”和“硬礼让”,以“不礼让、硬礼让、软礼让”3种礼让程度作为因变量,选取12个因素作为自变量构建礼让意向模型。为分析不同因素对右转车辆礼让行人意向影响的差异性,构建自变量在礼让模型中的优势比k。结果表明:右转车辆车速、人行横道长度、行人过街规模等因素k值大于1,表明这些因素增加了右转车辆对行人主动实施礼让的意向;行人行走在11~20 m长度的人行横道上会在最大程度上促使右转车辆停车礼让行人。
In order to improve the traffic safety of right-turning vehicles and pedestrians at two-phase signalized intersections,yield intention model based on multivariate ordered logistic model is developed to seek the factors affecting the intention of right-turning vehicles yielding to pedestrians.Based on whether the existing research factors have an impact on yield behavior of right-turning vehicles,manners of right-turning vehicles are further subdivided into"soft yield"and"hard yield",with three yield degrees of"non yield,hard yield,and soft yield"as dependent variables,and 12 factors are selected as independent variables.In order to analyze the differences of different factors on the intention of right-turning vehicles yielding to pedestrians,the odds ratio k of the independent variables in yield model is constructed.The results show that the k value of factors such as the speed of right-turning vehicle,the length of crosswalk,and the scale of pedestrian is greater than 1,indicating that these factors increase the intention of right-turning vehicles to actively implement yield to pedestrians,and pedestrians walking on the 11~20 m crosswalk will impel right-turning vehicles to stop and yield to pedestrians to the greatest extent.
