What goes into a Corridor Study?

Corridor Studies identify the range of options (also known as alternatives) that best serve existing and future transit demand for a specific study area. In each case, MDOT MTA and its partners will work with jurisdictional partners and the public to set corridor-specific goals and objectives to evaluate potential routes, modes, and service characteristics (stop/station locations and frequency).

Corridor studies look at:

Previous Planning Studies:
What can we learn from the past?

Interjurisdictional coordination:
How can these projects best fit other city, county, and state-level efforts?

Public Engagement:
What do riders, residents, and
employers think?

Market Analysis:
Who would be likely to use transit?

Travel Pattern Analysis:
Where do people want to go now and in the future?

Land Use Analysis:
What would be surrounding transit stops/stations?

What comes out of a Corridor Study?

It takes approximately one year for Corridor Studies to narrow down all of the possible ways to travel between destinations into a final group of two to three alternatives that will receive further engineering analysis. Each alternative offers a different approach to how the service would work, including these characteristics:

mode icon

What combination of limited stop or express bus, bus rapid transit, light rail, heavy rail, commuter rail, and other new technologies is the best fit?

alignment icon

Where would stops and stations be located and how close would they be to each other?

schedule icon

What type of frequencies and operating hours can you expect?

transport infrastructure icon

Transportation Infrastructure
What types of physical improvements, including dedicated right-of-way or new stop amenities would improve the customer experience?

What is the process?

The Project Team will work with local jurisdictions, institutional stakeholders, and the public to set goals and objectives to help compare options for route and stop/station locations as well as the type of transit (for example, bus or rail).


propose icon


The Project Team will gather small groups of representatives from local jurisdictions, community groups, employers, and other interested stakeholders to get initial feedback on a range of potential routes and modes.

The Project Team will identify a final 2-3 alternatives that will receive further engineering study.
