PURPOSES: This study identifies the policy changes in road infrastructure over the last 30 years, and rates user satisfaction using opinion mining techniques. METHODS: First, we collected a text data set of the keyword 'road transport services' from media articles published between January 1, 1990 and June 10, 2019 that were managed by the Korea Press Foundation. Next word frequencies were analyzed to extract keywords relating to important policy issues. Moreover, to ensure changes in user satisfaction level with the road infrastructure, sentimental analysis was used. RESULTS : The results indicate that policy issues changed significantly every 5 years. Public opinion on newly introduced advanced technology in road transportation was generally positive, and user satisfaction gradually increased with time. CONCLUSIONS: Prior to the implementation of new technologies in road transport services, public opinion must be surveyed to ensure that the mobility policies are convenient and satisfactory.
