The objective of this study was to find a reliable procedure for determining when an auxiliary lane is needed on freeway segments with four or more directional lanes. The analysis procedure needed to be able to predict the operations that occurred first on a ramp merge/diverge freeway section (no auxiliary), and then on a weaving section (auxiliary lane). The conventional 1985 Highway Capacity Manual method of analyzing ramp merge/diverge and weaving areas was summarized. Field data, from a ramp merge/diverge and a weaving section, were used in the HCS (HCM software) to demonstrate the weakness of the current procedure.
