Getting Started
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.
