Sub-problem 3a: Weaving Analysis

As the weaving and non-weaving vehicle speed equation shows, these speeds depend on weaving and non-weaving intensity factors that measure the influence of the movements on the overall speed. The calculations of the weaving and non-weaving intensity factors, Ww and Wnw, respectively, use equation 24-4 in the HCM 2000.

The values for the various constants depend on the type of operation within the facility (constrained or unconstrained). These values were derived from a multi-variable, non-linear regression analysis of field data.
