Why not use flaggers to manage traffic on very busy days?
No flagger can replace the technology and efficiency of our traffic signals, especially in a synchronized multi-intersection system; and the very busy days are becoming much more frequent.


Traffic signals at Banff’s intersections are synchronized to support travel down the main Banff Avenue corridor. On busy summer days, the northbound signal pattern is combined with green times specifically designed for high traffic volumes, with video detection cameras that support each direction. The cameras trigger a signal change if there is no traffic facing the current green light, and associate the extra, unused green time to the other movement. There is no point in time when the signals are not feeding traffic onto the bridge.


The RCMP advise that Banff’s intersections require two professionally trained traffic management officers (RCMP or Bylaw) for each intersection. This makes flagging expensive as well as ineffective at signalized intersections.
