This paper shows the application of measured effects in a dynamic routing method. Within this method a special feedback controller is designed behind a traffic model and control algorithm which borrows approaches from linear feedback control theory. The method avoids the use of origin-destination (OD) estimations as well as a prognosis with respect to uncertainties of models and parameters especially like the compliance rate. Thus parts of the traffic model can be seen as replaced by a feedback controller using measured effects of control instead of estimated effects of control. The efficiency of this approach is underlined by simulation results applying a macroscopic traffic flow model and an OD estimation to a real motorway topology. Data from loop detectors of the test site are used to bring the simulated scenario close to reality. (A*)
