The demands of modern society require the daily distribution of passengers in space and time. Due to the need for population flow, there is a need for high transport demand, especially in urban areas, which is why it is extremely important that the transport network can meet the growing demands of its users. Public transport is the main initiator of city life, so managing the logistics and quality of public transport is an increasing challenge. The basic task of public urban transport is to enable affordable mobility of the population of a certain area, optimal coverage of the area, adequate accuracy and frequency of the timetable. Timetables and an extensive transport network are important factors in the provision of a public transport service that must be of adequate quality to meet the complex demands of transport demand. The public transport of the City of Zagreb includes the tram, bus and railway transport system operated by the Zagreb Electric Tram (ZET) and HŽ Putnički prijevoz. The aim of this final paper is to explore the satisfaction of public tram transport users with several different aspects and to make suggestions for possible improvements in public transport by looking at its positive and negative effects. The results of the research showed that the largest part of the population believes that tram traffic in the City of Zagreb is satisfactory and can meet the key requirements of market demand.
