Challenges in today's time of ticket collection are in the area of control of passengers who travel to their destinations in public city transport vehicles. Ticket inspectors are still used during ticket collection control, whose function is to check all passengers who are currently in the public city transport vehicle itself. If the passenger does not have a paid or registered ticket, the ticket inspector will write him a fine according to the relevant regulations issued by the JGP operator. Inside JGP vehicles there are one or more registration devices that are connected via GPRS network or more recently via Wi-Fi signal to the central management system through which the entire system of registration devices in all JGP vehicles is monitored. There are also closed systems of control and collection of train tickets. Such systems are mainly used in METRO or BRT systems. METRO is a railway system that serves for the underground mass transportation of people in the urban areas of large cities or in their region, which can also include smaller towns and cities in their surroundings. The bus rapid transit system (BRT) is a superior bus transport system that offers fast, comfortable and cost-effective urban mobility, and it achieves this with its own lanes, fast and very frequent bus departures. They function in such a way that passengers arriving at a certain stop would have to go through a system of ramps where they register their train tickets and cannot access the JGP stop in any other way. The demand for public transport services is influenced by the tariff system, and the tool for implementing a successful tariff policy is the charging system. Therefore, it is necessary to develop a charging system and tariff policy that will satisfy both parties, the users of the public urban transport service and the providers. The goal is to provide or receive quality service at the lowest possible cost. The goals and purpose of the research in this final paper are billing systems in public city transport and analysis of the tariff system. I will compare tariffs based on examples of European and world cities, the analysis will reveal their good and bad characteristics. The paper will also contain an analysis of the collection system in the City of Zagreb and the state of the tariff system, which will be compared with other cities. In conclusion, the possibility of improving the tariff system of the City of Zagreb based on the experiences of European and world examples will be considered.
