OPTIMISING THE CONTROL PERFORMANCE OF TRAFFIC SIGNALS AT A SINGLE JUNCTION

The optimal control performance of a single signal-controlled junction is investigated. Two existing methods for analyzing this control problem are discussed. One of these, a combinatorial method, generates all possible control structures in terms of groupings of streams of traffic to have green together and the order in which right of way is granted. The other method allows an existing control structure to be optimized by convex programming techniques. Incompatibilities between these two approaches are illustrated and it is shown that they cannot be combined in a satisfactory manner. A new procedure is framed that allows a control structure generated by the combinatorial method to be optimized directly. This procedure is applied to an example junction to illustrate its use.
