Transportation Information and Data

Other Traffic Data: Recording, Daily Traffic and Turning Counts

Automatic Traffic Recorder (ATR)

Automatic Traffic Recorders collect data on how many vehicles use a particular roadway over a 24-hour period. ATR counts also provide information on the type and speed of vehicles.  
Data is collected by using rubber tubing that is stretched across a roadway and connects to a counting device. There are approximately 232 ATR stations in Peel Region.

Annual Average Daily Traffic (AADT)

Annual Average Daily Traffic is a calculation of the total number of vehicles that pass a certain place in an average weekday of the year.
AADT measurements are based on the data collected using Automatic Traffic Recorders.

Turning Movement Counts (TMC)

A Turning Movement Count (TMC), counts the movement of vehicles and pedestrians at an intersection. The count is done by hand during morning, mid-day and afternoon peak hours.
The data is summarized to show when the intersection is the busiest, which are the peak hours of use.
