Abstract:

The Highway Capacity Manual covers adequately the operation of weaving areas on freeways. Weaving on non-freeway facilities, however, has not been addressed as yet. This research effort presents a state-of-the-art procedural analytical approach and simulation models for the analysis of the level of service and operation of non-freeway weaving areas. Weaving under non-freeway conditions is classified into two broad categories; basic weave and ramp weave. The analytical models for these two weaving categories are calibrated and validated based on data obtained from several sites selected in the states of New Jersey and New York. New level of service criteria are developed for these two weaving categories. A FORTRAN program was developed to compute average weaving and nonweaving speeds and determine the level of service. In addition, simulation is used to develop a model for basic weave only. The simulation model is microscopic, enabling the user to study the dynamics of individual vehicles and the overall traffic flow.
