A delay model is recommended in the 1985 Highway Capacity Manual (HCM) for the level-of-service analysis of signalized intersections. The use of this model for the evaluation of traffic-actuated signal operations requires the knowledge of the average cycle lengths and green intervals associated with the signal operation being analyzed. A method has been suggested in the HCM to estimate such operating characteristics of traffic-actuated signal operations. The method, however, is not reliable. An improved method for estimating average cycle lengths and green intervals, limited to semiactuated signal operations, is described. The method, which is developed through analytical modeling and computer simulation, is sufficiently simple and reliable. Realistic examples are used to illustrate the application of the method.
