The REC continuously monitors transport-related problems and needs in the countries and cities of South Eastern Europe (SEE) and assists local stakeholders in identifying and solving the challenges they face. This book is a result of these efforts, summarising recent urban mobility challenges in the SEE region and featuring five public transport case studies (Tirana, Skopje, Belgrade, Zagreb and Istanbul). Based on the analysis of urban mobility challenges, the concluding chapter contains recommendations for future steps in SEE cities.
