The County of Simcoe Engineering Department monitors the vehicle traffic volumes along its road by means of an Annual Traffic Count Program. The Program consists of:
- Automated Traffic Counts - traffic volumes on County Roads
- Intersection Turning Movement Counts - traffic patterns at intersections
Annual Traffic Counts
The County road system is divided into three geographic regions and each region is counted once every three years. Seasonal traffic counts for each road are conducted (Spring, Summer, and Fall) and then averaged to obtain an Average Annual Daily Traffic value. This value is commonly referred to as the AADT.
AADT traffic values are used in the analysis of current traffic trends and growth rates along County Roads. AADT values provide important information used in the review of road improvement projects, traffic impact studies for proposed developments, and level-of-service ratings for maintenance operations.
A simple summary of all the AADT's values for the entire County Road network can be obtained below, free of charge. Detailed traffic count reports are available from the Engineering Department at a $25 fee per seasonal report. These reports include the directional hourly breakdown of traffic volumes along with speed and vehicle classification data.

Intersection Turning Movement Counts (TMC's)
TMC's are also carried out on many of the County's busy intersections. TMC's are used in the review of traffic signal and signal timing studies and turning lane warrants. TMC's are available from the Engineering Department at a fee of $150 per report.
