This report contains the results of field studies conducted to evaluate four types of basic, full traffic actuated signal control systems. Two signal phasing strategies were tested. These were three-phase and four-phase with two overlaps. Two small loop (point) detection patterns, single- and multi-point detection, were evaluated for each type of phasing. An assessment of these systems was conducted based on the results of statistical and observational evidence regarding their operational effects on queues and cycle models that relate queueing delay to traffic characteristics.
