abstract="The city of Phoenix recently completed a study designed to measure the effectiveness of 2-way left-turn lanes (TWLTL) throughout the city. TWLTL provides a sheltered storage area for left-turning vehicles on high-volume streets. The TWLTL offers many benefits including a substantial reduction in accidents, increased capacity, reduced delay and congestion, separation of oncoming traffic, and space for construction detours and other emergency uses. The concept has been expanded to include a sheltered storage area to facilitate left turns onto a major street. The study found that TWLTL in Phoenix is very effective in reducing accidents and improving service to driveways and side streets. TWLTLs also have been helpful serving as a limited refuge area for pedestrians and for improving overall street capacity.<p />",
