Vehicle data
Calgary’s vehicle‑focused transportation data helps us understand how cars move through our city streets each day. By looking at patterns in traffic volumes, speeds and driver behaviour, we see where our roads are working well and where they may need extra care. This information supports safer neighbourhoods, smarter planning and a transportation network that grows with Calgary.

Calgary Traffic Counts System
CalTRACS
For more than 40 years, The City of Calgary has been collecting detailed information about how vehicles move through our streets. Today, this long‑term record of traffic activity is available in one easy‑to‑use online tool: the Calgary Traffic Count System (CalTRACS).
CalTRACS brings together decades of vehicle data so we can better understand how traffic patterns are changing and how to plan for a safer, smoother and more efficient road network.
What CalTRACS shows you
CalTRACS provides a wide range of vehicle‑focused traffic data, including:
- How many vehicles travel through an intersection or along a roadway
- The types of vehicles using our streets (cars, trucks, buses, motorcycles, etc.)
- Turning movements and traffic flow patterns at key locations
- This information helps paint a clear picture of how Calgary’s road network is being used and where improvements may be needed.
Why does this data matter? Understanding vehicle activity helps The City:
- Identify traffic trends in neighbourhoods and across the city
- Plan for road upgrades, intersection improvements and traffic‑calming measures
- Support long‑term transportation planning and forecasting
- Provide residents with transparent, easy‑to-access information about traffic in their area
All data can be viewed through Quick View summaries or downloaded as full reports in PDF or Excel formats. Everything is free to access under The City’s Open Government License.

Traffic flow maps
Calgary’s traffic volume flow maps offer a snapshot of how our city moves each day, showing the average number of vehicles travelling along key roads across the city and downtown. By tracking these patterns year over year, we can see how Calgary is growing and where our transportation network needs investment and attention.
These maps help residents, planners and community builders understand the rhythm of our roads so we can continue shaping a safe, connected, and thriving Calgary for everyone.

Cordon counts
Central Business District
Cordon counts
Central Business District
Every year in May, The City conducts the Central Business District (CBD) cordon count to understand how vehicles move into and out of downtown Calgary.
This data highlights how drivers travel across the downtown boundary, including the number of vehicles, how traffic volumes change throughout the day, and how these patterns shift over time.
Counts are collected at approximately 31 locations around the CBD over a three‑week period.
The CBD cordon surrounds downtown with:
- The Bow River to the north
- CP railway tracks to the south
- 11 Street S.W. to the west
- The Elbow River to the east

Speed compliance maps
Speed compliance maps
Calgary’s speed compliance maps show how closely drivers follow posted speed limits across the city by comparing the posted speed to the 85th‑percentile speed (the speed most drivers naturally travel at). Using a three‑year summary of speed studies, these maps help highlight where speeds are comfortable and safe, and where streets need extra attention. This information supports safer neighbourhoods, thoughtful road design and a transportation network that reflects how Calgarians truly move.
