Traffic Counts

This traffic count data base contains raw traffic count information collected from local jurisdictions and the Michigan Department of Transportation annually and is included in the data base. The counts represent 24 hour two-way volumes unless otherwise noted. The data is not adjusted to account for any traffic flow changes that may result from seasonal fluctuations. All attempts are made to obtain counts during mid-week average flow conditions.

The user of this data should use all appropriate precautions and good judgment when referencing data contained within this document. GVMC staff does attempt to verify that the count data is reasonable, but due to the volume of data received each year some counts may appear to be higher or lower than expected. If you find a count location with a volume that does not seem reasonable please contact GVMC staff for verification.
