行人过街设施选择偏好的非集计模型

为提高行人的交通安全水平和过街设施的使用效率,研究行人对过街设施的选择行为.对中关村大街选择人行横道和过街天桥的402个行人进行问卷调查,内容包括行人特性、设施特性及行人对过街设施的选择特性;基于调查数据,分析了影响行人选择过街设施的因素,并建立了反映选择偏好的二元Logit模型.观测数据和模型预测结果对比分析表明,模型对行人选择人行横道和过街天桥的预测准确率分别为80.29%和85.66%.

Disaggregate Model for the Preference of Pedestrian's Crossing Facilities Selection

To improve traffic safety level and increase the efficiency of crossing facilities,the paper presents a methodology in studying selection preference of pedestrian crossing behavior.402 pedestrians were interviewed by a questionnaire about pedestrian's behavior of crossing crosswalk and pedestrian bridge in Beijing Zhongguancun Street.In the questionnaire,three parts are included,i.e.,characteristics of pedestrian,feature of facilities,and preference of facilities selection.Based on the surveyed data,factors influencing crossing behavior were analyzed and binomial Logit model was formulated.The results showed that 80.29% of crosswalk data and 85.66% of pedestrian bridge data out of the model formulated fitted the field data.
