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

Xu, D., Rouphail, N. M., Aghdashi, B., Ahmed, I., & Elefteriadou, L. (2020, January 1). Transportation Research Record Journal of the Transportation Research Board, Vol. 2674, pp. 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 *

topics (OpenAlex): Traffic control and management; Traffic and Road Safety; Transportation Planning and Optimization
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.
