Increasing Intersection Capacity with Additional Through Lanes. State-of-the-Art Studies/FY87 (Task 5).

摘要

A review of the literature and a state-of-the-practice survey were conducted of procedures relating to the addition of through lanes at intersections. The capacity and level of service change at the intersection is of interest, since the reduction in delays and congestion are the primary reason for adding through lanes. The total length of the additional through lanes, including in advance of and beyond the intersection and associated tapers is important in the effect on utilization and hence capacity. Definitive field studies and analyses are recommended to determine the minimum lengths for additional through lanes.
