A continuum model for freeway traffic flow is considered which contains a relaxation to equilibrium speed in anticipation of traffic change downstream. By including fluctuations the traffic flow model allows one to calculate speed distributions and derive early warning criteria. Sensor specification for traffic data acquisition on the basis of the derived incident detection and the equipment of a traffic control center are described
