The invention discloses a cell transmission model parameter calibration and verification method specific to variable speed limit control. Geometric characteristics and traffic flow data of expressway sections are collected. Fluctuation graphs of the traffic flow data along with time are drawn. Principal lines and traffic flow basic graphs of ramp cells under the variable speed limit control are calibrated based on the obtained data.
