The factors that influence the capacity of an all-way-stop-controlled (AWSC) intersection have been identified, and a procedure that can be used to estimate intersection capacity has been developed. A theoretical framework for a capacity estimation procedure was first postulated and then validated with field data collected at 20 sites. A statistical analysis of the factors that affect capacity was undertaken, and a method for the estimation of intersection capacity was proposed. The proposed model represents a logical procedure for the determination of the capacity of an AWSC intersection, given the number of lanes on each intersection approach, the distribution of traffic among the approaches, and the proportion of turning movements on each approach. The forecasting performance of this model is significantly better than that of two previously proposed methods for forecasting the capacity of an AWSC intersection.
