NEW SCHEME FOR TRAFFIC FLOW ESTIMATION AND CONTROL WITH A TWO COMPONENT MODEL
This paper proposes a control concept to reach high performance traffic flow on cross-country highways under changing demand and constitution of vehicles. For this purpose a two component model of traffic flow is developed which pays special attention to the influence of trucks within the traffic stream. This model characterizes traffic flow by the aggregate variables car-density, total density which relates to cars and trucks and average speed in a road element. Concerning the problem of estimation of these variables the realistic assumption is made that traffic sensors will be located only at distances of several kilometers. A control strategy is developed for this road unit using nonlinear programming and short time prediction. Basic features of a decentralized instrumentation of this concept are outlined.
