Recent OECD research, however, points to a number of key principles for enhancing the efficiency, sustainability and inclusiveness of urban transport financing in general, w'hich could perhaps help inform the current policy reflection in Korea (Table 1.6). Experience in OECD countries suggests that strengthening economic appraisal procedures and eligibility criteria for subsidies could improve the cost-efficiency of transport projects. Social inclusion can also be reinforced through land-value capture mechanisms, targeted subsidies for the neediest users and reasonable fare levels.
