MEDIAN U-TURN DESIGN AS AN ALTERNATIVE TREATMENT FOR LEFT TURNS AT SIGNALIZED INTERSECTIONS

Conventional intersection designs are frequently not capable of alleviating congestion without incurring significant improvement costs and increased conflicts. A few states are considering and applying nonconventional treatments for high traffic-volume intersections, especially those with high left-turning traffic volumes. Nonconventional intersections provide unique channelization of particular turning and indirect traffic movements. Consequently, capacity is enhanced and delay may be reduced when the number of signal phases is reduced. Moreover, safety benefits are possible with separation and reductions of potential conflicts. This article studies the traffic-operational benefits of signalized median U-turns for left-turning vehicles making indirect maneuvers. A discussion of possible safety benefits is also provided.
