Analysis of Parameter Sensitivity for Calibrating Microscopic Traffic Simulation Model

In order to study changes in traffic micro-simulation model of the degree of influence of each parameter on the simulation results, in the paper, based on the sensitivity theoretical analysis, a sensitivity coefficient is defined to compare the sensitivity of different parameters; sensitivity qualitative analysis of the average travel time of the single intersection each direction is the result of the parameters sensitivity tests' scatter diagram. The result showed that additive part of safety distance, average standstill distance, safety distance reduction factor, simulation resolution, max look ahead distance, multiple part of safety distance are the sensitive parameters affecting travel time.
