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

The Regional Traffic Counts Database (RTCD) is SEMCOG's central repository for all traffic counts. 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. Traffic Count Database System (TCDS) is updated immediately when an agency uploads a recent count to the system. 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 the database as separate records. Query our Traffic Count Database System (TCDS) hosted at an independent site.

Segment counts are taken approximately midway between the cross streets listed in the From Road and To Road fields; intersection counts are taken near the cross street listed in the At field. Some counts are for one direction only (northbound (NB), southbound (SB), eastbound (EB), or westbound (WB)), while others are 2-way totals as indicated in the Directions field. All locations have an Average Annual Daily Traffic (AADT) value, which is adjusted for seasonal, day-of-week, and axle correction factors. The unadjusted Volume Count represents the actual number of vehicles on the specific count date. The Volume Trend shows the difference in volumes from year to year. A location may have more than one volume count listed for different dates. Some locations will also have Speed, Classification, and Gap data. Additional details are available in the online Help documentation in TCDS.
