System limit control deserves the most efficient one that has beenapproved to be appropriate for traffic congestion conditions in foreigncountries. This paper accordingly tries to develop a traffic density controller to eliminate the traffic congestion. The macroscopic traffic model adopted in this paper will be introducedto domestic people. A traffic density controller is improved which is proposedfirst by C.C.Chien , Y.Zhang, A.Stotsky. The traffic controller is designed tooperate traffic system in a desired traffic density to prevent the amplification of traffic congestion. We proposed the density rules to set the density goals to cooperate with the density controller. Finally, we collected the traffic flow characteristics that are createdfrom the traffic data on domestic freeway system to fit in the adopted macroscopic traffic model. From the simulation of difference traffic situation: close partly lane, close fully lane, upper grade lane, we can see the traffic congestion has been eliminated by the proposed density controller.
