Traffic Counts

MDOT Employees at Work

Traffic Monitoring  is responsible for the collection of all types of traffic data including traffic volume, vehicle classification, turning movements and special studies as requested by department employees.  The reporting of traffic volumes is accomplished through two distinct methods involving the Continuous Count and Coverage (i.e Short Term ) Count programs. The Continuous Count Program consists of 52 permanent recorder sites located throughout the state, monitoring traffic volumes 365 days per year on an hourly basis.

The Coverage Count Program divides the state into three zones; the southern/coastal area, the central band and the northern/eastern portions of the state.  Traffic count and vehicle classification data are collected for 24 hours using road tubes and adjusted to an Annual Average Daily Traffic (AADT) volume. 

The need for more extensive vehicle classification data by the department has brought about the development of a Permanent Classification Program.  Currently we have 11 sites collecting continuous classification data with plans to install roadway sensors and classifier equipment for 6 additional locations.

The Traffic Monitoring Section is also responsible for the publication of the Traffic Volume Counts Annual Report. This book is available for download in the Adobe PDF format , or may be purchased in a hard copy for $13.00 via mail.
