In modeling the queueing behavior of vehicles for analyzing traffic-actuated signal controls, existing simulation studies have treated only queue discharge headways explicitly. Other vehicle-detector interactions, which govern the initiation, extension, and termination of a green duration, are largely embedded in obscure algorithms for processing vehicles. This negligence has led to misleading and unrealistic findings. Based on data collected at three intersections in Syracuse, New York, some basic characteristics of vehicle-detector interactions that should be accounted for in simulating traffic-actuated controls are described. Further studies are needed to establish baseline information for examining the role of such interactions in shaping control efficiency and for calibrating simulation models.
