Abstract

Optimal velocity model is used to investigate the spatiotemporal structure of a traffic flow pattern under an open boundary condition. Results show that the traffic flow on a freeway finds different dynamic states in real traffic such as synchronous flow (SF) in high density regions, stop-and-go state (SGS) in alternating pattern of jammed and free flow regions. It is found that influx perturbation at the on-ramp causes various oscillatory and stabilized uniform dense flow.
