SOME ENERGY CONSIDERATIONS IN TRAFFIC SIGNAL TIMING

Using computer simulation techniques to augment a mathematical approach, F. V. Webster developed a method of calculating optimal cycle lengths and splits for the isolated intersection. He showed that the proportion of vehicles stopped as a function of the timing pattern used may be estimated from equations using the computed queue lengths. The output of the Webster procedure coupled with a simple FORTRAN computer program can be used to achieve efficient energy management for vehicles using an intersection. Implications are that vehicle operators could conserve fuel by learning certain operating procedures. Turning off the engines while waiting for red lights at intersections is one recommendation. Suggestions for an education program to teach such concepts to motorists are presented. /HRIS/
