Traffic is an indispensable part of human everyday life, whose main role is to connect space. The central part of the work is focused on the study of the consequences of traffic that intensively affects society in the traffic area - noise. Noise caused by traffic is one of the key pollutants in the living and working environment of the modern world. The impact of noise as a consequence of traffic on humans is manifold, but it mostly results in a reduction in the quality of life and a negative impact on health by causing cardiovascular and psychological problems. Also, traffic has a negative effect on cognitive abilities, which endangers children and young people the most. This paper investigated the spatial differentiation of traffic noise in the area of the city of Rijeka, and a special emphasis in the research was on the impact of traffic noise on selected educational institutions in Rijeka. The research methods used in the preparation of the diploma thesis are spatial analysis in GIS and the method of data collection through a survey questionnaire. The aim of the work was to create a noise map, to define the parts of the city of Rijeka and the educational institutions most threatened by traffic noise, and to investigate to establish the impact of traffic noise on educational institutions. The results of the research showed that schools in the city of Rijeka are exposed to moderately loud and loud levels of traffic noise, and almost half of the schools have noise values higher than the highest permissible noise values for the zone intended for the existence of schools. Also, the research results indicated that the school's vulnerability to traffic noise correlates with the school's distance from roads and its categorization.
