Highway traffic data and statistics
Health related measures that were put in place due to the COVID-19 pandemic had a considerable impact on highway traffic. The impacts to traffic began in March 2020 and continued into 2021. The traffic data and statistics for 2020 and 2021 should be used with caution when looking for ‘typical’ traffic conditions or when estimating future traffic volumes.
For more information and statistics, see Impacts of COVID-19 Related Health Measures on Highway Traffic.
For traffic data and statistics on:
- Alberta highways in or near your community, use the traffic volume data map roads
- within major cities, such as Calgary and Edmonton, contact the municipality’s transportation department
Traffic statistics are estimates only. Alberta Transportation does not assume any responsibility for the use of this data without expressed written consent.
Highway traffic data is updated every year by the end of March.
