Intersection Safety Cameras (ISCs) are cameras that detect the travel speed of vehicular traffic. The ISC is also able to detect whether a vehicle fails to stop for the red light phase in a signalized intersection. ISCs are deployed at signalized intersections throughout the city with high collision rates and a history of serious injury or fatal collisions.
More information on this is available at: http://www.calgary.ca/cps/Pages/Traffic/Speed-on-green-and-red-light-cameras.aspx

This dataset describes proposed speed limits on Collector and Residential roads as per the new default speed limit bylaw within the City of Calgary that takes effect May 31, 2021.
