A shared, forward-looking vision of urban transport as an enabler of economic, environmental and social opportunities will play a key role in upgrading growth and quality of life in Korean cities. This figure only includes population living in predominantly urban regions (as defined in the OECD territorial classification). The sum of the share of population living in predominantly urban regions and that living in intermediate regions is 82.7%, compared with an OECD average of 73.7%. As of 2015, roads and railways accounted for around 45% and 33% of total traffic-related public investment, respectively (Kim, 2015).
