Day-to-day Approach for Path Choice Models in the Transit System: Analytical Evaluations and Simulation Results
P Velona, Universiti di Reggio Calabria, IT
The aim of this paper is to evaluate link flows and networks performances, such as travel times and levels of service, in day-to-day dynamics. In this paper the formulation of the modal split model is recalled, stressing the dependency of within-day and day-to-day dynamics of the transit service. The modal split is influenced by the day-to-day learning components, like in the private transportation systems. Once identified some components subject to day-to-day modification, some examples of system dynamics according to different supply evolution typologies are introduced. An analysis of the weight of the control parameters in the dynamic process is developed, considering the stability system conditions.
A simultaneous path choice model is considered, taking into account the dependence of some attributes,present in the function of systematic utility, from the congestion caused by the flow of the users of the service and from the congestion caused by the promiscuous lines where the public transport vehicles move.
