Traffic Counts

This program enables you to search SEMCOG's traffic count database and generate printable, easy-to-read traffic count reports.

The traffic counts stored in this database were collected and provided to SEMCOG by the Michigan Department of Transportation; by consultants specializing in traffic data collection; and by counties, cities, and villages in Southeast Michigan. Each count was taken during a continuous 24-hour period, beginning on the date indicated. Counts longer than 24 hours were divided into distinct 24-hour intervals and stored in this database as separate records.

All counts are unadjusted, meaning that no growth factors or seasonal, day-of-week, or axle correction factors have been applied. Please note that some counts are for one direction only (northbound, southbound, eastbound, or westbound), while others are two-way totals. SEMCOG periodically updates the database as new counts are received, so roads currently without counts available may have data in the future.
