All data points reported were collected using an automatic traffic recorder with an expected 95% +/- 5% accuracy.
The City of Ottawa provides this information in good faith but provides no warranty, nor accepts any liability arising from any incorrect, incomplete or misleading information or its improper use.
Annual Average Daily Traffic (AADT) represents the average 24-hour traffic volume at a location, averaged across all days of the year. All motorized vehicle data provided is based on either an 8 or 12 hour standard count. The collected raw total is then expanded to a 24 hour volume and factored by Ottawa’s Annual Average Daily Traffic (AADT) values providing a factored 24 hour value. Non 8 or 12 hour counts do not have AADT values calculated in this data set.
Update Frequency:
