针对大型超市购物出行的交通方式选择行为问题,以上海私家车车主为研究对象,以意向调查为行为数据的获取手段,研究包括自驾和出租车2种交通方式的大型超市购物出行交通方式选择行为.利用SPSS19.0软件,根据广义估计方程(GEE)对意向数据进行建模,建立了多种不同工作相关矩阵的候选模型,并从中选出最优模型.结果表明:月收入、职业、停车时间、超市距离和停车费用等因素对居民的超市购物出行方式选择具有较大的影响.其中,高收入的人选择出租车的意愿较低;在职人员(公务员、机关职员、事业单位和企业员工)相较于其他非在职人员更愿意选择出租车;停车时间较长的人更愿意选择出租车,停车收费的提高会导致自驾购物出行比例减少;超市距离的增加导致自驾购物出行比例增加.
For the problems of the mode choice about shopping trips to supermarket., taking the private car owners in Shang- hai as the research object, the choice behavior of travel mode to the supermarket of the drivers including self-driving and taxing was explored choosing preference questionnaire survey as the way to get behavioral data. The models for stated preference data were established using SPSS19.0 based on generalized estimating equations (GEEs) method, and several models with different working correlation matrices were established and the best model was selected from them. The results show that five main factors including income, career, parking time, distance between home and supermarket and parking fees greatly influence the choice behavior of travel mode to the supermarket of the drivers. Specifically, high-income people are more unwilling to choose taxi compared with low-income people; employed people (includes civil servants, office clerk, institution and enterprise em- ployees) are more willing to choose taxi compared with others; people need long parking time (compared with shorter parking ) are more willing to choose taxi, driving proportion for shopping reduces as the increasing of parking fees ; driving proportion for shopping increases as the distance increasing.
