要使旅行需求模型提供良好的预测，它们必须是因果关系;也就是说，模型应反映个人（和家庭）作出的旅行决定，并应纳入重要的人口和政策敏感的解释变量。这种认识导致了从聚合建模范式到非聚合建模范式的转变，这在实践中广泛使用的非聚合出行生产和模式选择模型中显而易见。然而，这种向非集计程序的转变尚未影响到在实践中采用的旅行吸引力和分布模型的基本规范。开发和估计的分类吸引端的选择模型，这将有助于取代目前使用的总旅行吸引力和分布模型。建议的非集计吸引端选择模型进行了比较与非集计等效的重力模型。
For travel demand models to provide good forecasts, they must be causal; that is, the models should represent the travel decisions made by individuals (and households) and should incorporate important demographic and policy-sensitive explanatory variables. This recognition has led to a shift from the aggregate modeling paradigm to the disaggregate modeling paradigm, evident in the widespread use of disaggregate trip production and mode choice models in practice. However, this shift toward disaggregate procedures has not yet influenced the fundamental specification of trip attraction and distribution models employed in practice. Developed and estimated were disaggregate attraction-end choice models that will facilitate the replacement of the aggregate trip attraction and distribution models currently in use. The proposed disaggregate attraction-end choice model is compared with the disaggregate equivalent of the gravity model.
