Urban green areas have an increasing value due to the accelerated process of urbanization around the world. The statistics of urban green areas are neglected, and the classification of urban green areas is not standardized at the global level. The paper examines the applicability of the AHP method for the purpose of determining the most suitable zone for arranging green urban spaces for vulnerable groups. Based on the criteria and their weighting coefficients, a model was generated using the AHP method. The selected green area is the area in the settlement of Novi Bokanjac, a rapidly growing part of the settlement Zadar with a large number of family houses. A large proportion of urban green areas in Zadar are not suitable for vulnerable groups, and are especially unsuitable for people with disabilities who face unorganized and inaccessible terrain in Zadar's parks. The paper also examined accessibility to green areas, which was compared with the Angst methodology. It was determined that only 16.6% of residential buildings have access to urban green areas larger than 2 ha at a distance of 300 meters from the place of residence. The classification of urban green areas according to Resler and according to the spatial management plan of the City of Zadar was carried out. Based on the spatial plan, the percentage of green areas is calculated, and its percentage values approximately 20 %.
