IMPROVED GRAPHIC TECHNIQUES IN SIGNAL PROGRESSION

The results of several research studies into graphic representations of traffic signal system settings and traffic flow are presented. The research began with the fundamental time-space diagram, which is universally understood by traffic engineers, and also with flow diagrams from the TRANSYT model. Three specific departures from these basic techniques are presented, which include time-location diagrams, forward progression opportunities, and platoon progression diagrams. All of these techniques apply to linear arterial systems or subsystems. Another graphic technique that applies to a network of coordinated signals is then discussed: signalized network animated graphics. Interpretation of signal timing-optimization strategies, namely maximal bandwidth optimization, is discussed using the platoon progression diagram technique. This analysis demonstrates the pitfalls of the maximal bandwidth approach, thus demonstrating the power of the analysis technique.
