调查了各种各样的因素中的每一个因素对旅行者连锁旅行的程度的相对影响。目的是通过经验确定哪些因素会影响旅行者在一次旅行中串联两次或更多旅行的倾向，以及这些考虑因素的相对重要性；更具体地确定城市中心对出行连锁的影响程度；并通过检查描述TDM相关影响的变量，评估特定运输需求管理（TDM）策略对出行链行为的潜在影响。建立了一个负二项回归模型，其中链中的旅行次数与家庭特征、旅行者特征、旅行特征和城市形态有关。对模型进行估计后，对各变量的显著性进行分析。这些类别的特征在统计上都是显著的。一些重要的变量有助于描述特定的TDM策略的影响，并讨论了这些变量对行程链行为的相对影响。代表TDM策略的一些变量增加了行程连锁水平，而其他变量降低了连锁水平。讨论了行程链和特定TDM方案之间的潜在政策冲突。
The relative effect that each of a wide variety of factors has on the extent to which a traveler will chain trips was investigated. The objectives were to empirically determine which factors influence a traveler’s tendency to chain two or more trips within one tour, as well as the relative significance of these considerations; to more specifically determine the level of influence that urban centers have on trip chaining; and to evaluate the potential effects on trip-chaining behavior of specific transportation demand management (TDM) strategies through examination of variables that describe effects associated with TDM. A negative binomial regression model was developed in which the number of trips in a chain is related to household characteristics, traveler characteristics, trip characteristics, and urban form. After the model was estimated, the significance of individual variables was analyzed. Characteristics from each of these categories were found to be statistically significant. A number of the significant variables help to describe effects of specific TDM strategies, and the relative effects of these variables on trip-chaining behavior were addressed. Some of the variables representing TDM strategies increased the level of trip chaining, whereas other variables decreased the level of chaining. Potential policy conflicts between trip chaining and specific TDM programs are discussed.
