Traffic Calming Tools

Vertical deflection means using a vertical physical feature in a roadway that changes drivers ’ course of path. These measures encourage drivers to slow down. 

• Speed humps

• Raised Crosswalks

• Sidewalk Extension  

• Textured Crosswalk

Horizontal deflection means using a horizontal physical feature in a roadway that changes drivers’ course of path. These discourage drivers from short-cutting, and may encourage drivers to travel more slowly.  They can also reduce conflicts and enhance the neighbourhood environment.

• One-Lane Chicane

• Curb Extensions

• Curb Radius Reduction

• On-Street Parking

• Raised Median Islands

• Traffic Circles

• Road Diets

Obstruction measures prevent drivers from using specific vehicle movements. These are typically used at intersections, but can also be used at some mid-block locations. Obstruction measures limit driver behaviour without limiting bicycle or pedestrian movements. Although obstruction measures are very effective at discouraging drivers from short-cutting, they are only considered when horizontal or vertical deflection measures are not effective or appropriate.

• Directional Closures

• Intersection Channelization

• Raised Median Through Intersection

• Right-in/ Right-out Island

• On-street Yield to pedestrian plastic sign

The main purpose of signage is to regulate drivers’ movements, not to calm traffic. When signage is used without physical traffic calming, it can create enforcement problems. For that reason, signage alone should not be used for traffic calming. However, signage can complement the physical devices installed through a traffic calming plan. 

• Traffic Calmed Community Signs

• Information Signage
