Abstract

This paper discusses and illustrates the effect that lane configuration can have on weaving-section operations, specifically, how land utilization may be substantially controlled by configuration. Data from the 1963 urban weaving-area capacity study are used to quantify these effects. Further illustration is given through the use of lane-transition matrices to model gross weaving movements under various configurations. The paper concludes that the weaving procedure in the Highway Capacity Manual leads to inadequate results because of the failure to differentiate between weaving and nonweaving lane requirements. That procedure is modified to take this into account and to avoid the design of sections without a proper total number of lanes. The modified procedure yields a configuration that prohibits proportional use of those lanes by weaving and nonweaving traffic.
