The objective of this study is to obtain more accurate origin-Destination (O-D)mathces with exact data such as toll collection system (TCS) O-D matrices, counted link vol-umes and express bus O-D matrices by EMME/2. First, an effect region of each tollgate was set up. In and out volumes of each tollgate were distributed to zones in the effect region of it The disthbuted O-D was assigned to the network composed of all tollgates and their ef-fect zones. Next, we adjusted the regional O-D mathces exduding TCS O-D mathces in or-der to reflect the observed volumes considedng the express bus and the assigned link volumes as additional ones. The assigned volumes with the estimated traffic -zonal o -D mathces pro-duced the only 17.9% error all over the freeways when they were compared to the real traffic volimes and the difference between assigned link volumes and counted ones is reduced very much all over the counted links.
