Modelling Traffic Flow at Multi-lane Urban Roundabouts

  title={Modelling Traffic Flow at Multi-lane Urban Roundabouts},
  author={Ruili Wang and Heather J. Ruskin},
This paper proposes Multi-stream Minimum Acceptable Space (MMAS) Cellular Automata (CA) models to study unsignalised multi-lane (twoor three-lane) urban roundabouts. Through detailed space considerations, using Cellular Automata (CA) and the Multi-stream Minimum Acceptable Space method, heterogeneity and inconsistency of driver behavior and interactions in cross traffic at entrances of roundabouts are simulated by incorporation of four different categories of driver behavior (i.e., conservative… CONTINUE READING
