Driving Behavior Parameter Sensitivity Analysis Based on VISSIM

Abstract:

The determination of the parameter set to be corrected is the premise and key of microscopic traffic simulation model’s calibration. In order to find out the sensitive parameter, this paper chooses Ronghua Road and Wing King Street intersection and the Shangdi Roundabout as experiments, and selects the queue length and travel time as the evaluation index, makes sensitivity analysis of calibrated parameters by microscopic traffic simulation software Vissim. It adopts a line chart method, range analysis and sensitivity coefficients to make comparative analysis of the evaluation results. At last, sensitivity parameters in intersection and roundabout are not identical.
