基于活动的城市老年人出行行为特征及其关联性研究--以昆明市为例

摘要

针对基于出行的时空特征分析在解释老年人不同活动出行行为差异上的不足，根据昆明城市老年人407份有效问卷调查和54份追踪访谈，对基于活动的出行行为特征进行分析。采用结构方程模型分析方法，对出行行为特征参数间的关系进行建模计算，得到了属性、活动因素与出行行为以及出行行为各参数间的关联性。研究结果显示：老年人不同活动的出行特征差异显著，与活动密切相关的出行行为特征参数间有较强的关联性，表现为活动对出行方式和出行强度、出发时刻对出行方式、出行方式对出行强度具有较强的影响。%Aimed at the problem that the differences in the elderly travel behavior under different activities can’ t be explained well by the travel-based space-time characteristics analysis methods, according to the data of 407 effective elderly travel questionnaire surveys and 54 follow-up interviews in Kunming, the travel behavior char-acteristics based on activities are analyzed.The relationship among travel behavior characteristic parameters is mod-eled and calculated by using the structural equation model method.The correlation between attributes, activity fac-tors and travel behavior and the correlation among travel behavior parameters are obtained.The result shows that the travel characteristics in various activities of elderly are significantly different, and there is significant relevance a-mong the travel behavior characteristic parameters which are closely related with the activities of the elderly.It is shows that activities have effect on travel mode and travel intensity , departure time has effect on travel mode , travel mode has effect on travel intensity.
