Abstract

North Carolina State University carried out a comprehensive study and evaluation of alternative software packages for signalised intersections (SIDRA, TRANSYT, HCS/HCM, Signal 94, HCM/Cinema, EVIPAS) for the North Carolina Department of Transportation. SIDRA was rated best on all accounts (model usability, quality of signal optimization and delay model evaluation) and recommended for use as the standard model. The report concluded: “SIDRA’s powerful combination of high model usability, superior matching of field delays at the lane group level, versatile optimization features, and graphical user interface makes it the model of choice from this study.”.
