        To collect preliminary data for transportation planning and policy making in the rapidly changing transportation environment in the Seoul metropolitan area, two different surveys on travel behavior have been recently conducted: the Household Travel Survey within the capital region, which is a census on individual trips that has been conducted since 1996, and the Passenger Travel Survey between regions and in the metropolitan areas, which has been part of national transportation research since 1998. However, with the amendment of the National Transport System Efficiency Act and the release of the first Guidelines for the National Traffic Survey, a revision of methods and contents of existing surveys is required. Two types of surveys are planned to be done jointly, but there appears to be various obstacles such as differences in survey times and methods, or weak data links. This study analyzes the recently amended National Transport System Efficiency Act in order to come up with necessary actions and to figure out the difficulties in the National Passenger Origin-Destination (OD) Travel Survey, which is currently under development. Firstly, Choice-based Sampling has been suggested as a supplementary survey to the administrative sampling method. Secondly, as a means of increasing sample size, a supplementary OD survey for bicycles and freight has been proposed, Also, to make better use results of household travel surveys, it is recommended to develop an advanced modal index, to estimate public transit OD through transportation card data, and to improve passenger counting systems that include subway transfers.
