This work investigates passage time of hi pass system usage and non usage vehicles on cheonggye, pankyo, and seongnam tollgate according to traffic, vehicles sort and delay time and quantitatively compute emission of air pollutants (CO, NOx, VOCs, TSP) and fuel consumption amount using COPERTⅢ model according to vehicles sorts. Reduction rate of emission on hi pass system usage vehicles appeared more about 50% than on general tollgate usage vehicles. If whole vehicles use the hi pass system, Reduction rate of emission about CO, NOx, VOCs, TSP, total air pollutants and fuel consumption amount showed 53%, 20%, 68%, 39%, 48% and 45% respectively.
