will be based on MPO-established boundaries.
– Other geographic area definitions that may be
appropriate for specific major metropolitan areas
may be proposed by the State, and concurred by
FHWA, based on supporting information related to
specific metropolitan areas.

5. Routes of Significance

• Determined / identified by States
• All information requirements of information
for Interstates in metropolitan areas apply
– Exception: Travel time information not required
for non-limited-access roadways (e.g., arterials)
• Implementation required by November 2016

6. Next Steps

measures, methods for making information
available, etc.
– Potential linkages to other programs
(performance management, road weather, etc.)
