A base-case model was created first, and it was calibrated to best resemble the conditions experienced during the data collection period. The measured volume inputs were put in, incremented into 5-minute intervals.

study METHODOLOGY
The calibration of a FREQ model involves observing the similarities and differences between simulated and observed conditions and making adjustments to the model parameters.
Cooperative ramp metering simulation
Nowadays ramp metering is used in cooperation with additional control approaches like variable speed limit control (VSLC)
