Modelowanie zjawiska zmiany trasy przejazdu w dynamicznym rozkładzie ruchu w sieci drogowej

The article addresses problem of representing rerouting phenomena within macroscopic Dynamic Traffic Assignment (DTA) framework. By rerouting we mean changing the currently chosen path, after receiving some information about an unexpected traffic event. We very broadly define here unexpected event as any relevant traffic information that is not known in advance by at least some percentage of drivers and implies changes in the perception of the supply side. We addressed the above problem twofold by a) saving and then reloading directed flows for each newly calculated demand pattern based on new information and b) handle above restricting internally within the RCM. Numerical examples show the results of the proposed models where rerouting phenomenon can be observed.
