The traffic count database contains raw traffic count information collected from local jurisdictions and the MACC. 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. MACC staff does not attempt to verify that the count data is reasonable 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 MACC staff for verification.

MDOT’s Transportation Data Management System
The Data Collection and Reporting Section at MDOT collects, analyzes, summarizes, reports, and retains detailed traffic data and travel information for 36,000 miles of federal-aid roads in Michigan, with additional reporting requirements for the 83,000 miles of local roads. Traffic data collection consists of short-term counts/studies, year-round data from the continuous count sites, and special studies. The data collected is provided to the Federal Highway Administration (FHWA) on a monthly and annual basis. Click to access MDOT’s traffic count database.
The MACC, in partnership with MDOT, the City of Holland, and County Road Commissions, annually rate our area’s Federal-Aid roads. We are responsible to report the condition of 50% of our roads every year; therefore MACC rates Ottawa County one year and Allegan County the next.
Submitted ratings help identify and prioritize future road resurfacing projects.
Pavement Surface Evaluation and Rating (PASER) is a visual survey of the condition of the surface of the road. It rates the condition of various types of pavement distress on a scale of 1-10. This system is used by most Michigan road agencies.
