“…Hence, extra subsidies must be provided, and in order to efficiently use national funds, it is necessary to review the degree of PSO achievement by policy, specifically. In the case of Europe, research on PSO policies in air transport is actively being conducted [4,5]. Regarding social equity of public transportation services, research is mainly conducted to evaluate the overall service through indicators such as the Gini coefficient or total demand and supply [6,7].…”

As Korea provides a fare-free policy for subways only, there are objections to geographical equity, and the need to expand it to the entire public transportation system is being discussed. However, expanding policy scope in line with an aging society will soon pose sustainability problems. Hence, policy changes, similar to that of countries that provide fare-discount policies for the elderly or apply different discount rates for each travel mode, are needed. However, providing the same policies for all cities may differ from the benefits the target group wants. Thus, this study investigated the preference of the elderly living in major cities in South Korea for discount policies by travel mode. The study aims to provide a strategy for choosing the travel mode that should provide discount policies by combining regional and individual attributes. The latent class model is employed to classify stated preference data collected from the survey. The estimation results show a significant preference heterogeneity depending on the level of subway supply by region, and a policy focused on subways would be more reasonable in cities with sufficient subway infrastructure. In addition, providing additional bus discount policies only for trunk lines will help improve sustainability.

The literature suggests that a country’s economic development is directly related to the efficiency of its transportation system. While the importance of a well-functioning transport system for economic growth and poverty reduction is widely acknowledged, there is limited quantitative research demonstrating this relationship. Many studies have separately applied data envelopment analysis (DEA) to analyze highways, airports, railways, and harbors. However, they have yet to analyze all modes and their relationship with economic development comprehensively. Consequently, this paper seeks to address this gap in the existing literature. The objective of this study is to demonstrate that transportation system. To this end, we employ DEA and consider a range of operational variables, including airports, railways, highways, and harbors. Furthermore, we examine the relationship between transportation efficiency and several economic and social indicators, including gross domestic product (GDP), human development index (HDI), and carbon dioxide (CO2) emissions from the transportation system. Our findings reveal that Brazil exhibits the lowest relative efficiency when compared with the G-7 countries and South America. Additionally, it demonstrates medium efficiency within the BRICS group (Brazil, Russia, India, China, and South Africa).
