Corridor Planning

Corridor planning uses the region’s major arterial roadways as its primary frame of reference to examine transportation patterns and needs along prominent routes of regional travel. A corridor perspective provides an ideal scale for providing strategic guidance on regional transportation issues. Advantages of corridor-level analysis include:


It offers a natural scale at which to examine the movement of commuters, freight, customers, visitors and other notable users of the region’s transportation system.


It provides an opportunity for higher precision in monitoring the performance of transportation facilities and services than would a region-wide approach.


It encourages a more complete investigation of non-transportation strategies, such as land use planning and zoning, for addressing transportation challenges.


It offers an appropriate framework for multi-state transportation planning efforts, since corridors, especially trade corridors, handle significant amounts of through trips.


The corridor planning approach is already familiar to SWRPC towns, NHDOT and neighboring regional planning commissions in New Hampshire and Vermont.


It can highlight regional transportation issues while simultaneously focusing on localized problems, promoting the engagement of local officials and stakeholders and a greater opportunity for addressing local issues, needs, plans, actions, and impacts.


It provides a useful perspective for examining multi-modal transportation options along key regional routes.

SWRPC utilizes corridor-level analysis prominently in its long-range transportation plan, Southwest Connects. It’s also served as the framework for standalone studies that we’ve conducted on NH Routes 9, 10, 12, 101 and 202. Check out our media library for copies of the studies.
