Warrants for left-turn lanes

Most states use accident, traffic-volume, or delay data as guidelines for installing left-turn lanes. Computer simulation of these data compares statistics of intersections with left-turn lanes to those without. The study found that special lanes always lead to improvement in traffic flow, but noted that all intersections cannot accommodate a special lane. The recommendations specify the accident rate, critical-volume determination, and the rate of traffice conflicts which warrant a separate left-turn lane. 10 references, 6 figures, 4 tables. (DCK)
