Automatic Analysis Method and Demonstration of Micro Simulation Parameter Sensitivity
Micro simulation model parameter calibration is a prerequisite for the scientific application of simulation technology.To address the problems of complicated process,large amount of experiments and long time consumption of micro simulation model parameter sensitivity analysis,an automated implementation method of micro simulation parameter sensitivity analysis based on decision tree method is proposed,including four modules of experi-mental design,simulation model assignment and operation,result summary and sensitivity analysis.The study provides a detailed description of the implementation process of each module and empirically analyzes the sensitivity of various parameters in the micro simulation model to the three indicators of macroscopic traffic flow delay,vehicle operating speed and traffic flow rate using the expressway intertwining area as the simulation scenario.
