PROPOSED ANALYTICAL TECHNIQUE FOR ANALYZING TYPE A WEAVING SECTIONS ON FRONTAGE ROADS

The analysis of nonfreeway or slow-speed weaving sections is documented. Previous research in this area has been limited almost exclusively to freeway weaving sections. Specifically, Type A weaving areas on frontage road facilities with ramps on the left side were evaluated. Special consideration should be given to both the length of the section and the number of lanes when designing the geometrics of a weaving section. Access points such as driveways can also have a significant effect on traffic operations within these sections. It was determined by previous weaving studies as well as this research that speed was not an adequate measure of effectiveness because of its insensitivity to volume. Two additional measures of effectiveness were studied: density and lane changing intensity (LCI). Density was also eliminated because of its relationship at constant speeds. Models were developed to predict LCI using three levels of service. These models require only the identification of geometric conditions and traffic volumes to predict lane change operations. The evaluation of performance measures for the LCI model found it to be an effective means of nonfreeway weaving analysis. This methodology is also consistent with the approach used in the 1985 Highway Capacity Manual.
