Place-based knowledge of transport patterns at various spatial scales is fundamental for sustainable mobility planning in rural tourism areas. Our purpose in this paper is to report on a study carried out between 5 March and 5 May 2024 with the focus on mapping transport activities and places with mobility deficits in the rural tourism border municipalities of Malung-Sälen, Älvdalen, Trysil and Engerdal in Sweden and Norway. We used a Public Participation Geographic Information Systems (PPGIS) survey to gather information on travel patterns and identify places in the four municipalities that require transport improvements. The study included citizens, second homeowners, and tourists. We received 1,426 responses to the survey and 1,758 unique locations have been identified by respondents as being in need of transport improvements. Of these, preliminary results show that Mälung-Sälen has the greatest need for improvement, leading the way with 966 locations identified. Not surprisingly, the use of diesel or petrol cars dominates both every day and leisure mobility in all municipalities. The dominance of carbon-intensive car-based travel in the region exacerbates climate change and poses a significant challenge for planning and facilitating a modal shift to more sustainable transport systems. This study is unique because it provides empirical data from several stakeholder groups, making it possible to analyze the perception of the need for transport improvements among different groups. Another novel contribution is the cross-border context for the study which offers analysis of mobility both within a country and between two Nordic countries. The results aid in understanding current mobility requirements in the region, providing useful knowledge for future sustainable transport planning.
