This paper proposes a new freeway traffic management scheme, which takes advantage of vehicular sensor network and V2V(Vehicle to Vehicle)/ V2I(Vehicle to Infra) 2-way communication environments of the ubiquitous transportation system. The proposed scheme pursues to maintaining traffic flow stability to prevent from or at least delay the flow breakdown and as a result, to maintaining the productivity.
Speed control strategies according to the traffic flow states were proposed. Simulation testbed was built for simulation experiments. The simulation results showed that the proposed speed control algorithm significantly improve traffic flow condition of the simulation network. But it fails to prevent from getting congested when flow level increases although it works well to a certain level of flow. The speed control for the congested state should be incorporated in the proposed algorithm, which remains as a further research
