| 摘要： | This report presents three approaches to modeling multimodal and intermodal transportation network problems for evaluation of transit performance and asset management. The first approach is an automobile assignment-based multimodal approach, which captures bus movements in the simulator, but assigns only automobile trips to shortest paths under the assumption that the mode split is fixed. For this model, an inner assignment dynamic user equilibrium (IADUE) assignment algorithm was developed to replace the method of successive averages (MSA). Whereas the MSA approach, which has been the state of the art in simulationbased assignment models, assigns vehicles to paths probabilistically, the IADUE approach systematically searches for the equilibrium assignment. The automobile assignment-based multimodal model has been implemented in the VISTA dynamic traffic assignment (DTA) software and is being used to evaluate the regional impacts of TSP in Chicago. |
