• Abstract:
  The researchers established that DTA modeling was a suitable approach for performing a bottleneck analysis at a regional scale since it provides an ideal balance between traffic realism and computational efficiency. In consultation with the Project Monitoring Committee the researchers developed a test bed DTA model of the MoPac Expressway, which also included the street network between MoPac to IH-35 and Cesar Chavez Street to 35th Street. The extended street network allowed for studying route-switching behavior of commuters after the geometric reconfiguration. VISTA software was chosen for this study since it met the scope of this project. The research team has extensive experience with transportation modeling using VISTA, and the availability of its source code meant that new features and updates could be added as needed. Its web-based interface provides flexibility and platform independence.
