Results of extensive research on actuated signal control methods are presented. A method for predicting actuated signal timings, and analytical models for predicting various performance statistics (delay, queue length, queue clearance time, proportion queued), that are implemented in the SIDRA software package are described. With actuated signal timings, equal degrees of saturation do not necessarily result, and the minor movements may get lower degrees of saturation than the major movements, indicating inefficient operation with long cycle times. Comparisons of SIDRA estimates of delay, back of queue and queue clearance time for actuated signals with those predicted by microsimulation as well as those observed at a real-life intersection are presented.
