JAMMING TRANSITION INDUCED BY A STAGNANT STREET IN A TRAFFIC-FLOW MODEL

A cellular automaton (CA) model is presented to simulate a traffic jam induced by a single stagnant street. The effect of a stagnant street on the dynamical jamming transition is investigated by the use of a computer simulation. The jamming transition describes the boundary between the moving phase in which cars are moving and the jamming phase in which all cars are stopped. It is shown that the jamming transition occurs at a lower total density of cars with an increasing local density of cars in the stagnant street. We find the phase diagram representing the moving phase and the jamming phase.
