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.

Exhibit 5-7. Museum Road Facilities for Analysis

Name

Facility Type

Existing Control

Case Study Interest

Museum

Road

Signalized Urban Street

  • Signals/TWSC

  • No coordination

  • Multimodal purpose. Vehicular mobility is not the primary consideration.

  • Substantial uncontrolled mid-block pedestrian activity

North-South

Drive

Signalized

Intersection

  • Actuated signal

  • Protected-permitted phasing

  • Pedestrian displays

  • Demand is expected to exceed capacity

  • Queues block access at adjacent intersections

Reitz Union

Drive

Unsignalized

Intersection

  • TWSC

  • Demand is expected to exceed capacity

  • Signalization will be difficult because of geometrics and proximity to N-S Drive

  • Heavy LT volume into new facility

  • One leg has insignificant traffic

  • Signalization will require geometric modifications

Center

Drive

Signalized

Intersection

  • Pretimed signal

  • Pedestrian displays

  • Two phase with turn restrictions

  • Unusual approach configuration, including one-way approaches

  • One approach is a staging area for buses

 

Newell

Drive

Signalized

Intersection

  • Actuated Control

  • Pedestrian displays

  • Protected LT phases on the arterial only

  • Request for additional LT protection

  • Request for exclusive pedestrian phase(s)

  • Lower vehicular volume permits consideration of double cycling as a means of improving left-turn capacity and pedestrian quality of service
