Modeling Framework for Capacity Analysis of Freeway Segments: Application to Ramp Weaves

TRANSPORTATION RESEARCH RECORD, 2674(1), 148–159.

By: D. Xu n, N. Rouphail n, B. Aghdashi n, I. Ahmed n & L. Elefteriadou*

Contributors: D. Xu n, N. Rouphail n, B. Aghdashi n, I. Ahmed n & L. Elefteriadou*

TL;DR: A new modeling framework for the analysis of freeway segments that distinguishes between congestion effects caused by high v/c ratios from turbulence caused by merging, diverging, and weaving traffic, thus greatly simplifying the model form and its extensibility to other freeway segment types.
