THE IMPACT OF EXISTING AND PLANNED TRANSPORT INFRASTRUCTURE ON THE SPATIAL DEVELOPMENT OF SLOVENIA: THE CONCEPT OF THE SPATIAL PLAN OF SLOVENIA

Abstract

Transport infrastructure is a key driver of spatial development, settlement patterns, and regional economic dynamics. By determining levels of accessibility and connectivity, transport systems influence the spatial distribution of population, economic activities, and services. This paper examines the impacts of existing and planned transport infrastructure on the future spatial development of Slovenia, with particular attention to settlement structure and regional accessibility. The analysis combines theoretical perspectives from regional development theory, accessibility theory, and land-use transport interaction models with the strategic objectives of the Concept of the Spatial Plan of Slovenia. The study demonstrates how transport infrastructure contributes to the development of a polycentric settlement system, reduces regional disparities in accessibility, and strengthens functional linkages between urban centres. Special attention is devoted to planning concepts such as “60-minute Slovenia,” “30-minute regions,” and “15-minute local centres,” which aim to ensure equitable access to services and employment across the national territory. The results indicate that coordinated spatial and transport planning plays a critical role in achieving balanced territorial development, improving economic competitiveness, and supporting sustainable mobility in Slovenia. This paper aims to examine how existing and planned transport infrastructure will influence Slovenia’s spatial development under the new Concept of the Spatial Plan of Slovenia.
