The report summarizes research into the relative functional and cost efficiencies of the one-man crew when compared to alternative two- or three-man crews for the collection of refuse. Four basic analytical techniques were used: comprehensive field surveys; nationwide survey data analysis; time-motion studies; and a mathematical model. The comprehensive field surveys were applied to four municipal collection systems and two private-firm collection systems. The time-motion studies compared field times in three cities with Methods-Time-Measurement values developed under controlled laboratory conditions. A mathematical model was designed to permit simulation of the refuse collection system. The model is a formula which expresses the interrelationships among the variables affecting collection time and system cost. Tables and charts have been prepared to support and illustrate the information developed, and the conclusions and recommendations which have been based thereon. (Author Modified Abstract)
