The aim of the research is to provide a numerical evaluation of the occurrence of New European Bauhaus (NEB) principles in urban plans, using four key indicators: GI (green infrastructure), POS (public open space), PSN (public and social needs), and UR (urban reconstruction). The initial step in the research involves determining numerical quantitative indicators with target reference values, which are then used as a measure of compliance with the vision of the NEB. Indicators are modeled based on elements embedded in urban plans and implemented in a framework for evaluating these plans. Through the analysis of collected data, a comparison is made with the set goals and values of the NEB, thus enabling the assignment of ratings for occurrence and identification of areas where improvements are needed. The research results for Rijeka point to the need for planning new green areas, maintaining and developing street networks, and increasing pedestrian and park areas. Additionally, there is a suggested need to increase content to meet public and social needs and expand areas planned for urban reconstruction. The research results emphasize the importance of monitoring and adjusting urban plans to the NEB platform to achieve sustainable and balanced urban development goals, highlighting the need for continuous improvement in the quality of urban planning.
