Cell transmission model parameter calibration and verification method specific to variable speed limit control

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. Key parameters for describing decrease of bottleneck traffic capacity and stop-and-go phenomena of the expressways are calibrated. The average over speed amplitude of drivers under a current speed limit value is calibrated. The practical compliance conditions of the drivers to the variable speed limit control are described. After calibration is finished, the traffic flow data is output through simulation of a cell transmission model; the traffic flow data is compared with the actually measured traffic flow data, thus verifying the precision of a simulation model. According to the method, the randomness of determining the parameters of the cell transmission model subjectively is covered; compared with the cell transmission model under default values, the calibrated and verified cell transmission model under the variable speed limit control has higher pertinence; therefore, the traffic flow characteristics obtained through simulation are more consistent with the actually measured traffic operation; and various traffic analysis results based on the simulation results are more reliable.
