For freeway links and connectors, the Wiedemann 99 model should be selected for car following model. Figure (1) showing the default car following parameter set is a good starting point but it may need to be adjusted to better match real-world conditions, especially when trying to match flow rates and achieve particular capacities. Any suggested values for these parameters that are outside the proposed ranges (see Table 2) should be documented with its reason and application in the Confidence and Calibration Report.
