摘要：	This research intends to develop a microscopic framework to model the airport related traffic and emission implications; an approach to calibrate the driving behavior parameters for airport road and a case study of IAH. The microscopic framework integrates a microscopic traffic simulation model and a modal emission model, which mainly includes identification of simulated airport road network, calibration and validation of traffic simulation, data transfer from simulation model to emission model, design of modeling scenarios, and conducting the traffic simulation and emission calculation for each scenario. The GA-based calibration approach defines the index of simulation accuracy as sum of squared errors (SSE) between the collected speeds and the simulated speeds at the cross-sections along the road. The program named AUTOSIM was developed to indirectly express the complex and nonlinear relationship between the SSE and the driving behavior parameters. The computer program implementing the GA-based approach was also developed to search the optimal parameters values simultaneously and easily. IAH was modeled as the case study. The field speed data were collected using GPS. The calibrated optimal values of the VISSIM driving behavior parameters were derived for IAH loop, which resulted in a 50 percent decrease of SSE value. The number of speed errors greater than 10 percent at the cross-sections decreased from 22 to 2 for the selected physical section. The produced emissions of each vehicle by second show that the emission profiles well reflect the trends of the speed profile. The calculated emissions for one week of August 2002 are 61.430kg of CO, 26.849kg of HC, 271.896kg of CO2 and 61.603kg of NOx.
