3D Traffic Simulation for Intermodal Safety and Security

This project involved the construction of a 3-D Miami downtown transportation simulation model to study and visualize the traffic operations of different transportation modes and investigate the impacts of potential security and safety events in the Miami downtown area. The 3-D model (including buildings, highways, and elevated guideways) was constructed using AutoCAD and a Geographic Information system (GIS). A traffic simulation model was built based on Cube Base/Voyager/Dynasim. In this study, the 3-D simulation model was used to assess the elapsed time for a specific evacuation scenario. The results show that it would take at least six hours to evacuate the traffic in the downtown area to the nearest external stations for a given emergency event.
