Mixed-Logit Latent-Class Model of Strategic Route Choice Behavior with Real-Time Information (12-2867)

We study drivers¡¯ route choice behavior in a driving simulator with real-time traffic information. A strategic route choice refers to a look-ahead decision taking into account future diversion possibilities at downstream nodes based on real-time information not yet available at the time of decision-making. A mixed Logit model with two latent classes, strategic and non-strategic route choice, is speciﬁed and estimated. The estimates of the latent class probabilities show that a significant portion of route choice decisions are strategic and subjects can learn to make more strategic route choice as they have more experience with the decision scenarios. Non-parametric tests also show that a parallel driving task does not affect strategic thinking ability, which might be caused by the simplicity of the test network. The findings suggest that a realistic route choice model with real-time information should consider both strategic and non-strategic behavior, which potentially vary with the driver¡¯s experience.
