Abstract: Summary A simple CA model (CA-184s2ss) is shown to reproduce, at freeway bottlenecks, elements of the observed phenomena of two-capacity flow, including both breakdown and recovery flows, and of wide moving jams. Notwithstanding that both of these phenomena are incompatible with classical kinematic-wave models (KWMs) of traffic flow, sufficiently coarsely time-aggregated CA-184s2ss simulations are shown to be approximated modestly well by the KWM, with a single suitable empirically determined capacity at the bottleneck.
