A local feedback controller for oversaturated intersection control based on dynamic road traffic models

A dynamic road traffic model is applied to traffic control design at an isolated intersection to determine control sequences. Developments in linear systems control theory are applied to address two continuing problems that are keys to effective road traffic system operations: road traffic models; and traffic signal control. The control of an oversaturated intersection is formulated as a linear systems control problem on the basis of mathematical models. These models are utilized to develop local traffic signal control strategies under various traffic conditions.
