Looking for a traffic calming idea? Delineators are road posts that are used to promote safe driving by marking the limits of the road and roadways. They have retro-reflective strips that allow vehicles to better identify them at night, by reflecting the light emitted by automobile headlights.

Often presented in the form of flexible posts screwed to the ground for better solidity, the delineators are particularly useful for guiding circulation. When visibility is reduced or if pedestrian and bicycle path traffic is near the road, their reflective color or band will stand out and help the driver avoid an accident. They are often used as part of vision zero, a plan that aims to bring the number of accidents down to zero.
