Estimating walking access area for rail transit station based on discrete choice model

基于离散选择模型的城市轨道交通站点步行吸引范围估计（英文）

The discrete choice model is used to estimate the walking access area of rail transit stations while considering the influence of existing competition from other traffic modes. The acceptable walking access area is determined according to the willingness of passengers to walk who prefer rail transit compared with bus and automobile. Empirical studies were conducted using the survey data of six stations from the rail transit in Nanjing, China. The results indicate that the rail transit is more preferable compared with bus and private automobile in this case when excluding the influence of individual and environmental factors. It is found that passengers tend to underestimate their willingness to walk. The acceptable walking access area of every rail transit station is different from each other. Suburban stations generally have a larger walking access area than downtown stations. In addition, a better walking environment and a scarcer surrounding traffic environment can also lead to a larger walking area. The model was confirmed to be effective and reasonable according to the model validation. This study can be of benefit to the passenger transportation demand estimation in the location planning and evaluation of rail transit stations.

采用离散选择模型对轨道交通车站步行吸引范围进行估计,当在某个距离下相比于公交和私家车乘客更愿意选择轨道交通出行时,认为该距离为乘客可接受步行范围.利用南京地铁6个站点的调查数据进行了实证研究.结果表明,在个人和环境因素相同的情况下轨道交通比公交车和私人汽车更具吸引力.研究还发现乘客往往会低估他们步行的意愿,对于不同的轨道交通车站可接受步行范围有所差异,其中郊区的车站通常比市区的车站具有更大的步行吸引范围.此外,良好的步行环境和较差的周边交通环境也会导致更大的步行吸引范围.检验结果表明该模型具有良好的有效性和合理性.该研究有助于轨道交通站点选址规划中的客流需求预测以及轨道交通站点的评价.
