As the world becomes increasingly interconnected, transborder and cross-border transportation plays a fundamental role in facilitating economic growth, enhancing cultural exchanges, and promoting regional development on a larger scale. Connectivity refers to the extent to which different regions and nations are linked via transport systems. For transborder and cross-border movement, both ‘hard connectivity’ according to physical infrastructure and ‘soft connectivity’ referring to service or/and policy dimensions, should be examined from a door-to-door perspective. Accessibility, on the other hand, focuses on the ease with which people and goods can reach their destinations. This includes various factors such as travel time, cost, available options, and reliability. Mobility refers to the ability of people and goods to move freely across borders, taking into account issues such as border controls, customs procedures, and regulatory frameworks. Moreover, as events such as Brexit, which have affected regionalisation on different scales, suggest that transborder and cross-border transportation studies should re-evaluate ‘borders’ from dynamic perspectives of connectivity, accessibility and mobility.

In the study of transborder and cross-border transportation, issues about infrastructure disparities, border effects, bottleneck problems, regulatory gaps, cultural barriers, social equity, and environmental sustainability should be widely discussed. This session aims to explore the various aspects of transborder and cross-border transportation, including connectivity, accessibility, and mobility. Potential topics could include, but are not limited to:
