摘要 文献中充分认识到正确指定选择集以避免参数有偏差的重要性，这对于空间选择模型尤其重要，因为空间选择模型的替代方案通常很多且有些人为定义（即交通区域）。选择集是指个体在决策过程中考虑的离散备选方案的集合，它是由决策者可用的所有备选方案组成的通用选择集的子集。本文的目的是回顾为模拟此类集合形成而提出的各种方法。讨论了每种方法的优点和缺点。
Abstract The importance of properly specifying choice sets to avoid biased parameters is well recognized in the literature and it is particularly relevant for spatial choice models where alternatives are generally numerous and somewhat artificially defined (i.e. traffic zones). The choice set refers to the set of discrete alternatives considered by an individual in the decision-making process which is a subset of the universal choice set that consists of all alternatives available to the decision-maker. The objective of this paper is to review the various approaches that have been suggested to model such set formation. Strengths and weaknesses of each of these approaches are discussed.
