Traffic Safety Engineering
There is no silver bullet that will end traffic injuries and fatalities. Human error is inevitable and yet unpredictable. Safety engineering is about designing the transportation system to anticipate human error so the consequence is not severe injury or death.
From curb extensions in communities to redesigning intersections on major roads, engineering measures build a safer, more livable city.
Through ongoing review of collision data, planners and engineers identify and develop projects designed to improve safety on Edmonton streets. These engineering changes provide results that we can document. Here is a simple example: If a mid-block left-turn across a busy road results in 13 collisions each year, by eliminating that turning point, we reduce collisions by 13 and have prevented injuries and possibly deaths.
Engineering improvements to traffic safety include installation of:
- Protected-only left turn phases at signalized intersections to reduce left-turn-across-path collisions.
- Pedestrian signals, crosswalk markings, and pedestrian amber flashers at pedestrian crossings to improve pedestrian safety
- Driver-feedback signs to let drivers know if they are speeding
- Retroreflective tape and additional traffic signal fixtures to improve the signal visibility at signalized intersections
