A Calibration Algorithm for Vehicle Emission Estimation using Driving Simulator

Traffic simulation has become one of the most effective ways in emissions estimation due to the high difficulty in massive collection of real-world emission data occasionally. Driving simulator has been widely applied in traffic studies. Because the high association of operating mode distribution with vehicle emissions, based on the Environmental Protection Agency (EPA) approved emission estimation model MOVES, Vehicle Specific Power (VSP) and Operating Mode Bins (OMB) have strong relationships with vehicle emissions. VSP and OMB are directly obtained through field observations. The driving simulator is a good tool to emulate the vehicle movement, and thus could be used to synthesize VSP and OMB for emission estimation purposed. This paper develops a fuzzy based scenario to calibrate the simulated OMB and real OMB. Calibration result show that the OMB distribution errors are reduced for more than 50%, and the vehicle emissions are very similar (with a error of less than 2%.)
