Microscopic simulation of traffic flow at signalized intersection based on cellular automata

Modeling traffic flow dynamics using cellular automaton (CA) allows one to run a complex signalized intersection simulation with comparatively low computational effort. The authors examine various realistic generalizations of the basic cellular automation model used in traffic simulation and give a new CA model to describe the dynamic traffic transition at a signalized junction. Traffic jam and delay induced by a two-dimensional crosscut road are discussed. Using this model, the authors simulate the dynamic traffic flow in each direction changing lane under different rules. Comparison of the output shows the effectiveness of the input traffic management strategies.
