2020 Deerfoot Trail Corridor Study
The 2020 Deerfoot Trail Corridor Study was a joint initiative between Alberta Transportation and The City of Calgary to develop a plan to manage traffic and improve safety on Deerfoot Trail.
Significant technical work was completed to confirm and analyze the current problems on Deerfoot Trail. A microsimulation traffic operations model was created for the entire corridor and portions of the adjacent road network using The City’s Regional Transportation Model (which anticipates future travel demand) and more than 4.5 million lines of Bluetooth data (which is converted into origins and destinations to verify how people use Deerfoot Trail today). The traffic operations model, combined with the public input gathered in 2016, identified capacity and weaving (vehicles entering and exiting the freeway in the same space) as the primary current and future issues, as well as problems on the freeway caused by issues on the adjacent road network.
History
The original alignment of Deerfoot Trail was planned to follow the Nose Creek Valley, pass through the community of Inglewood, and then continue along the Bow River Valley. Community opposition and natural and built constraints resulted in the alignment we see today.
