TWO-STAGE TURN QUEUE BOX GOAL
Improve the safety of cyclists at multi-lane intersections which are performing left turn movements.
WHAT IS IT?
Two-stage turn queue boxes are used at intersection for cyclists attempting to turn left. This is most useful at multi-lane signalized intersections. Typical bike lanes are not conducive to left turn movements which cross multiple lanes because it requires them to merge into traffic. With a two-stage turn queue box the cyclists turning left stop in the intersection in the queue box aligning with the desired bicycle facility and waits for the light to shift.
POTENTIAL CONFLICTS
This intersection configuration is much safer for cyclists however it does add time their travel as they may have to wait though two light cycles.
