Traffic Operations and Monitoring

Here at the Mobility Operations Centre (MOC), we monitor Calgary’s traffic and road conditions, 24 hours a day, seven days a week. When a traffic issue is found, our staff respond. Some of the ways we do this includes changing signal timings, lane reversals and pushing out traffic information to the public.

Alberta Transportation Partnership

The City has partnered with Alberta Transportation to help keep traffic flowing along Deerfoot Trail and Stoney Trail. When a traffic issue is detected, the MOC shares this information with drivers through our roadside electronic signs. This information can include lane closures, changing travel times, major construction and alternate route options.

How the MOC controls signals

The MOC is now able to synchronize our traffic lights faster. With new second-by-second signal monitoring, the MOC can now adjust Calgary’s signals when needed. This means less waiting for lights to change to colour and improved traffic flow. 

Lane reversals

The MOC operates several lane reversals in Calgary that help reduce traffic congestion. A lane reversal allows traffic to flow in different directions at different times of the day. They are mostly used in Calgary to provide additional lanes for motorists during peak traffic hours.

How the MOC informs travellers

The MOC provides Calgarians with the latest traffic updates through numerous channels. This includes our online Traffic Map, Roadside Traffic Alert Signs, on our @yyctransport Twitter account and on The City’s Traffic Advisory Radio station at 107.9 fm.

Emergency management

In emergency situations, The City’s Mobility Operations Centre activates its command center called the Roads Operation Center (ROC).
