论文摘要
在过去的十年中，自行车共享获得了相当大的实践和研究关注。作为人力驱动的运输模式，它似乎对旅行长度更敏感，因为人们可以将共享的自行车带到一个势不可挡的地方，那里的地方太远了，或者选择它在去附近的地方时简单地替换步行。但是，很少有研究注意它，即建筑环境对自行车共享需求的差异化影响。为了填补空白，本文确定了自行车共享痕量数据的自行车共享跳闸长度的阈值，并采用了半参数地理位置加权的泊松回归（SGWPR）模型来研究建筑环境与自行车共享需求之间的关系，并考虑了不同长度的关系，考虑了不同的长度。结果表明，建筑环境对城市地区的自行车共享需求有异构影响，并且各组的行程长度有所不同。这些发现有助于理解建筑环境与自行车共享需求之间的关系，并为放置和派遣共享自行车提供支持。
Bike-sharing has received considerable practice and research attention over the past decade. As a manpower-driven transportation mode, it seems more sensitive to trip length, since one could take a shared bike to a destinated place where is too far to walk, or choose it for simply replacing walking when going to a nearby place. However, little research has paid attention to it, i.e., the differentiated effects of built environment on the bike-sharing demand with trip lengths. To fill the gap, this paper identifies a threshold of bike-sharing trip lengths from bike-sharing trace data, and employs a semiparametric geographically weighted Poisson regression (SGWPR) model to investigate the relationship between built environment and bike-sharing demand with different lengths considering the heterogeneity in the relationship. The results show that built environment has heterogeneous effects on the bike-sharing demand in urban areas, and the effects differ across groups with trip lengths. The findings contribute to understanding the relationships between built environment and bike-sharing demand, and providing supports for the placements and dispatchment of shared bikes.
