Obstructions and Closures

Another tool the City uses to calm traffic is to obstruct it. We can use partial and full roadway closures, intersection diverters, raised medians and right-in-right-out channelized islands. These devices reduce infiltrating traffic on neighbourhood streets.

Advantages:

• reduces road user conflicts and volumes
• requires little or no enforcement

Disadvantages:

• penalizes local traffic access
• reduces access to transit, emergency services, delivery service, etc.
• complicates road maintenance efforts in the vicinity of devices
• potential to divert both local and through traffic to parallel or alternative routes
