Printable Version Printable Overview, Introduction, and Getting Started

Several issues will be considered as we begin this case study, including the scope of the analysis, the stakeholders and their perspectives, the overall goals for the analyses, the performance measures to be used to quantify results for comparison, the tools to be used in performing the analyses, the data requirements of these tools, and the technical details that arise from using the HCM methods in this case study.

Scope of the Analysis
The intersections along this section of Museum Road provide unique characteristics that lend themselves to a variety of analysis techniques. The Museum Road facility itself presents some special considerations that must be taken into account in all analyses, due principally to the close intersection spacing and the significant amounts of pedestrian, bicycle, and bus activity.
