A made-in-Ottawa technology meant to protect cyclists at some controlled intersections is posing a whole new risk, according to one city councillor.
Revert reds — also known as red reverts — have been in place for years. They occur when vehicles, including bicycles, cause sensors in the road to trigger a traffic light change.
The sensor technology is meant to speed the flow of traffic through intersections and cut down on emissions from idling vehicles. But if the vehicle or bicycle moves past the sensors too soon, the signal immediately switches back to red and the cross traffic gets a green light again, posing a potential danger for cyclists.
