摘要：This research investigates the day-to-day dynamics of a transportation system under the provision of Advanced Traveler Information (ATI). The ATI provided to the travelers is either the historical or the predicted travel costs, based on which travelers make their own predictions accordingly and further choose the routes. Day-to-day models are formulated to investigate the stability of the transportation system when ATI is either the historical or predicted travel costs. The analysis shows that publishing the predicted costs harms the stability of the transportation system. Further, in a special case that the historical travel costs are used as ATI and travelers respond perfectly to their predictions, the day-to-day dynamic is shown to be equivalent to the logit-based first-in-first-out dynamic and be globally stable under separable link cost functions. Finally, we model the logit-based proportional switch adjustment process under the provision of predicted travel costs and prove it to be globally stable.
