Analysis of Freeway Weaving Sections

The freeway weaving analysis methods in the 2000 Highway Capacity Manual (HCM) are based on research conducted from the early 1970s through the early 1980s. Subsequent research has shown that the methods' ability to predict the operation of the facility is limited. Other concerns about the methods include lack of consistency in application with other freeway methods, the difficulty of determining the service measure in the field, and the difficulty of comparing the analysis results with the results of simulation modeling. The objectives of this project are to develop improved methods for capacity and level-of-service analysis of freeway weaving sections and to develop a revised Chapter 24 of the 2000 HCM. Compatibility of the methods with those of other HCM freeway chapters, particularly the chapter on Ramp Junctions, should be assessed.
