The paper deals with the issue of supporting public passenger transport and integration in order to ensure the sustainable mobility of population. It highlights the importance of public passenger transport and the reasons why the population prefers cars. The objective of the paper is to analyse public passenger transport without mutual integration of individual transport systems resulting in the fact that it is not sufficiently able to compete with individual automobile transport. It is suggested the process of public passenger transport integration as well as the design of key elements in order to increase road safety. In addition, the paper confirms the hypothesis that by supporting of public passenger transport and increasing the number of individuals transported by public passenger transport, road safety increase can be achieved.; Ovaj rad se bavi problematikom potpore javnog prijevoza kao i njegovom integracijom da bi se osigurala održiva mobilnost populacije. Ističe se značaj javnog prijevoza te se navode razlozi zašto generalna populacija preferira automobilski prijevoz. Cilj rada je analizirati javni putnički prijevoz izuzevši individualne načine prijevoza te se zaključuje da se javni ne može mjeriti sa individualnim automobilskim transportom (po broju putnika). U radu se predlaže način integracije javnog putničkog prijevoza i ističe ključne elemente za povećanje sigurnosti na cestama. Dodatno, ovo istraživanje potvrđuje hipotezu da se poboljšanjem javnog prijevoza kao i povećanim brojem korisnika istog povećava sigurnost na cestama.
