Shared information space between cross-border capital regions

Abstract

This paper explores the role of digital tools and open data in shaping planning processes in cross-border regions, focusing on the case of Tallinn and Helsinki in the Baltic Sea Region. Although not officially recognised as a cross-border region, the two cities share multiple joint projects, including a proposed tunnel connection. The study examines how information and communication technologies can support the creation of a digitally enhanced shared urban space and address the challenges of integrating physical and virtual dimensions of planning. It argues that functional cross-border regions require shifting the discussion from logistics and infrastructure to shared urban values, services, and citizenship. The paper also highlights methodological challenges in mapping digital layers of cross-border spaces, given rapid technological change and the complexity of multiple actors across scales. The findings suggest that actively using ICT to create shared knowledge and interaction could serve as a benchmark for planning international cross-border urban regions.
