Turning Stop & Go…to Go Go Go

Let’s just put it out there – there aren’t too many fans of the traffic congestion on St. Albert Trail. So how do you turn Stop & Go…to Go Go Go?

The answer: technology!

The City is using technology and innovation to improve road network safety, mobility and efficiency. Technology has been installed along St. Albert Trail to help improve traffic flow, as well as monitor and report on how corridors and intersections are functioning to ensure effectiveness. This technology sets the stage to shift the current traffic signal operations towards an adaptive style of signal control.

What are adaptive signal controls?

Adaptive signal controls use detectors to capture real-time information that allow the signals to respond intelligently and continuously as traffic flow changes and fluctuates throughout the day.

Is a heavy stream of traffic all of a sudden leaving a major event? The signals see the rush and adapt to move the vehicles and pedestrians safely and efficiently.

This is a substantial change from what’s currently taking place, which uses “time of day” plans that are based on anticipated conditions rather than real-time conditions.

Benefits:

  • Reduced travel time, delay and congestion
  • Smoother traffic flow with less “stop and go” conditions may also decrease collisions

Is this underway now?

The City has already installed one form of the technology and is monitoring and evaluating its performance on St. Albert Trail. Each day, the technology is continuously adapting and learning. It will be constantly measuring all of the traffic flows in and out of St. Albert Trail while dynamically changing or ‘adapting’ the signal timings to fit the traffic load.

Alternative forms of adaptive technology may be applied to other key corridors and intersections to evaluate its effectiveness and impacts before looking at applying this technology on a wider scale.

While it may not happen overnight, adaptive signal control is just one way the City is using technology and innovation to help people and goods move more efficiently and effectively throughout St. Albert. For more information, visit the Intelligent Transportation Systems page.

Quick Facts:

  • Bluetooth Travel Time devices have been installed at four locations along St. Albert Trail and use Bluetooth technology to capture travel time from one point to another. Information will be used to evaluate how the road is functioning and may also be shared with users to assist in pre-trip planning. 
  • On September 10, 2018, the City released its first Intelligent Transportation Systems Strategic Plan and Implementation Strategy.
