Transport infrastructure opens new routes and creates connections. It increases prosperity by generating economic opportunities, reducing transport costs and supporting agglomeration economies. However, the increased traffic flows also generate environmental and social costs. In Korea, the amount of paved roads increased dramatically between 1951 and 2014, from 580 kilometres to over 87 000 kilometres. This expansion of Korea’s expressway, highway and major road network has created benefits for cities and rural areas across the country, contributing to both economic growth and inclusiveness. This rapid development of road infrastructure and motorisation has also resulted in relatively high traffic fatality rates. This report combines empirical research on the relationship between road infrastructure, inclusive economic development and traffic safety with an assessment of policies and governance structures to help governments find ways to create effective, safe and inclusive transport infrastructures.
