among many model parameters, the "saturation flow" parameter for signalized intersections and the "critical gap and follow-up headway" parameters for unsignalised roundabouts and sign-controlled intersections are identified as key parameters for calibration to match real-life traffic conditions. at the same time, the "queue space (jam spacing)" parameter used in "back of queue" modelling is identified as a key parameter in general due to its role in approach short lane modelling for intersections and lane blockage (queue spillback) modelling for networks.
