The City of Calgary continuously reviews collisions at intersections to identify where changes can be made to improve traffic safety. These reviews have identified some right-turn islands throughout the city that can be changed to improve traffic safety.

The options for improving a standard right-turn island include changing it to:

High entry angle right turns

A high entry angle right turn slows traffic. It also changes the angle motorists who are approaching the right-turn need to look to see on-coming traffic in the lanes that they will be turning in to.

Dual lane signalized right turn

Reviewing right turns for improvements

To decide what type of change needs to be made to a right turn island, we look at:

  • The types of collisions from the collision review.
  • The volume of traffic making the right turn and the volume of traffic that would be conflicting with the right turn.
  • The type of vehicles that will be making the right turn.
  • The distance a motorist needs to travel to get to the next intersection (or on/off ramp) after the right turn.
