Traffic signals : capacity and timing analysis.

Traffic signal capacity and timing analysis techniques are presented as an aid for detailed geometric and operational design of signalised intersections. The report introduces several changes to the existing methods, a basic change being from "phase-related" methods to "movement-related" methods. A critical movement identification method is presented as a procedure which automatically satisfies minimum green time constraints and allows the use of different degrees of saturation for different movements. Detailed discussions of opposed turn, lane utilisation and short lane problems are presented.
