Tests of Cycle Length Transition Methods Deliberating Offsets for Dynamic Progression with WISDOM

WISDOM (Wirelessly Interconnected Signals for Dynamic and Optimal Management), being developed traffic control and management systems in Korea, provides operators with a functionality to refine progression groups by combining and separating signalized intersections in real time. When an intersection is newly added to or extracted from a signalized intersection group, the traffic control system needs a time, design time, to determine new signal timings for the intersection and a time, transition time, to shift to the newly designed signal timing from the initial ones. It has been indicated that either a long or a short transition time would reduce the performance of the system. In this study, four different transition methods utilizing different lengths of transition periods were tested in simulation environment. They include a single, double, treble, quadruple cycle length period transition methods. It was concluded from the test that a single cycle length signal timing transition method performs better than or at least equal to any of the other methods for all operational conditions. The test results suggest adopting the single cycle length transition method as a general guideline for signal timing transition.
