Why do you take that route?

AbstractRoute choice refers to the choices of roads among a set of possible alternatives made by human drivers while navigating through an urban area. The purpose of this paper is to determine whether a particular context factor among the variables that a researcher is interested in causally affects the route-choice behavior of drivers. There is limited literature that consider the effects of various factors on route choice based on causal inference. . To fill this gap, we carried out a study using Immersive Virtual Environment (IVE) tools to elicit drivers’ route choice behavioral data, covering drivers' network familiarity, education level, financial- concern, etc, apart from conventional measurement variables. Having context-aware, high-fidelity properties, IVE data affords the opportunity to incorporate the impacts of human-related factors into the route choice causal analysis.
