MDOT NTFA
Welcome to Michigan Department of Transportation, Non Trunk Line Federal Aid Mapping Application.
Traffic segmentation details may be viewed or exported in multiple formats.
The Non Trunkline Federal Aid Program, NTFA, was established to
meet the HPMS reporting requirement to provide a count based annual average daily traffic (AADT) on
all federal aid roads. The NTFA is a cross agency traffic data collection program for the non trunkline
federal aid road network. Traffic data collection is coordinated between Cities, Counties, MPOs, RPAs,
and MDOT on both three and six year cycles and reported annually to FHWA.
This site allows the user to review and download the road segments, AADT,
source, and schedule data for the NTFA network.
