14.5.2 Design Considerations

A CGT should be considered in the following instances:
  • Intersections with three legs;
  • Heavy through traffic volumes on the major street;
  • Moderate to low left-turn traffic volumes on the side street;
  • No driveways along the major street opposite the side street; and
  • A limited number of pedestrian crossings across the major street or with an alternative pedestrian crossing location nearby.
