A New Feed-Back Process by Means of Dynamic Reference Values in Rerouting Control

摘要

This paper provides an approach to extend the classical two-component control scheme con-sisting of a traffic model and an algorithm. Within this scheme a special feed-back controller is added which uses dynamic reference values. Within the framework of a motorway contorl system it is shown that this approach allows for modular and subsidiary system architecture. In an example of rerouting control this extended scheme needs neighter origin destination (OD) estimations nor traffic forecasts with respect to incretatinties of models and parameters in particular the compliance rate. Practical requirements for the algorithms are derived from a test site. The efficiency of this approach is assessed by simulation results utilising a macroscopic traffic flow model and OD estimation from a real motorway topology. Data from loop detectors of the test site are used to bring the simulated scenario close to reality. It is shwon that the proposed algorithms are insensitive to estimation errors of the traffic models to be expected when applying the models to reality.
