An empirical analysis of capacity drop at sag bottlenecks based on the continuum traffic flow theory

Abstract

This study conducts an empirical analysis of the capacity drop phenomenon at sag bottlenecks based on the recent advanced continuum traffic flow theory. We first show the underlying phenomena, components, and consequences of the theory in a concise manner. We then compare several theoretical predictions with real data, qualitatively and quantitatively, which demonstrates that the theory brings us new interpretations of observations.
