Weaving occurs when merging traffic streams entering a freeway from an on-ramp cross over diverging traffic streams exiting the freeway via a nearby off-ramp. The intense lane-changing activity which typically occurs in weaving areas can create significant operational problems. Thus, weaving sections often represent bottleneck locations in urban freeway systems. Our procedure predicts vehicle flow rates in critical regions within a weaving area as a function of prevailing traffic flow and geometric conditions. Predicted flows are then used to assess the capacity or level of service of the weaving site. The proposed model was developed using large amounts of empirical and simulation data.
