Background
Dartmouth College’s Real Estate Office acquired several adjacent under-utilized buildings in downtown Hanover, New Hampshire. They have proposed an ambitious mixed-use project incorporating several Smart Growth design features, including dual footprint parking and adaptive re-use of historic structures. Resource Systems Group was retained as a team with Engineering Ventures and the Office of H. Keith Wagner to conduct the following:
- Develop traffic signal design plans and signal timing plans for the re-alignment of the South Main Street and Maple Street intersection;
- Evaluate access to the site’s underground parking facility; and
- Estimate off-site traffic impacts during peak periods.
Project Elements
|
- Identified existing traffic flow deficiencies and needs for new signal system elements and timings;
- Designed an intersection plan to include: location of electrical supply, controller cabinet, electrical conduit, vehicle detection loops, pull boxes, traffic signals and mast arms, and pedestrian signals; and
- Developed and refined a signal system equipment list to develop a cost estimate and for use in project bid documents.
- Developed and ran a microsimulation model to determine optimal routing schemes for site-generated traffic.
- Project to be installed: Summer 2005
