As an important part of airport ground transportation, terminal curbside has both static and dynamic traffic cha- racteristics. The data collecting method aiming at traffic characteristics of airport terminal curbside is designed. Four parameters including desired speed, acceleration, dwelling time and standstill distance are extracted to re- flect the traffic characteristics at airport terminal curbside. Then, the parameter calibrating approach is proposed and a case study is conducted in T3 terminal at Beijing Capital International Airport. VISSIM is used to develop the simulation platform for airport terminal curbside traffic and the distribution characteristics is calibrated by using field data. Results indicate that after calibration the simulation accuracy is improved significantly and the errors are controlled within 10%.
