离散选择建模框架在出行需求建模中起着主导作用。它特别适合具有紧凑选择集的选择，例如模式选择。然而，对于诸如路线或目的地选择之类的空间选择（通常以大量替代方案为特征），选择集形成步骤提出了至关重要的且迄今为止尚未解决的方法论和经验问题。本文介绍了解决这些重要问题的步骤。本文的核心是一个公开的基于网络的调查工具，它可以采用实证方法来形成目的地选择集，并且在协作工作中也具有潜在的用途。其中包括对与目的地选择集形成相关的问题的详细分析以及模型估计的第一种方法。
The discrete choice modeling framework plays a dominant role in travel demand modeling. It is particularly suitable for choices with a compact choice set, such as mode choices. However, for spatial choices such as route or destination choices, which are in general characterized by a large number of alternatives, the choice set formation step poses crucial and to date unsolved methodological and empirical problems. In this paper, steps towards solving these important problems are introduced. The core of this paper is a publicly available Web-based survey tool that enables an empirical approach to destination choice set formation and that also has potential use in collaborative efforts. A detailed analysis of the problems associated with destination choice set formation and first approaches for model estimation are included.
