A study of three recently installed signal systems in Maryland included travel time, fuel consumption and traffic volumes for all movements at all signalized intersections. A field after study, a field before study (system modified to represent before - uncoordinated - conditions), and computer simulation runs were compared, using travel time, delay and fuel consumption MOE's. Both NETSIM and TRANSYT 7F models were used. It was shown that computer simulation models can be used to predict changes in these parameters which can then be used to make decisions on which of several candidate new signal systems will likely be the most cost effective to meet budget constraints.
