Why aren more left turn arrows installed?
Turning arrows take time away from through traffic and add to the congestion at an intersection. If we can eliminate a turn arrow, we would be able to extend the green light for through traffic. The result should be less congestion and better synchronization for the through road. Drivers could normally make left turns during gaps in the opposing through traffic. Left turn arrows are installed where turning vehicles are consistently delayed for one or two cycles. If you notice this situation at any signalized intersection, please contact the Engineering Services Department Traffic Section.
