This thesis describes the history and types of public transport and public scheduled transport. The legal part that regulates public transport has been processed and the next segment is European road, rail and inland waterways in relation to Croatian road, rail and sea public transport. The capital cities Zagreb, Vienna, Oslo, Warsaw and Budapest were further analyzed. After their comparison, there is a transition to integrated passenger transport. In this part, the prerequisites for a successful integrated network, connection with urban planning, legal provisions, impact on the environment, and finally the European integrated systems are described. Public transport or mass transport describes one method of transporting people (usually in an urban area), and is carried out on specific lines or routes and according to a planned schedule. Types of public transport are: buses, trolleybuses, trains, metro, tram, boats and ferries, taxis. Public transport is a type of passenger or cargo transport available to all users of transport services under the same conditions and is carried out for commercial purposes, in order to make a profit for the carrier. Europe has a sophisticated and comprehensive public transport network that connects urban, suburban and even rural areas. In order to reduce traffic, improve environmental sustainability and improve the mobility of their residents, European countries give priority to efficient and sustainable public transport. While in Croatia, road transport includes a wide network of state, county and local roads along with a system of long-distance highways. Maritime transport can be divided into river transport and maritime transport. Although electrification and double-track tracks are not particularly widespread in the railway industry, high-speed trains are used on several routes. The concept of the Integrated Passenger Transport system is the latest and best modern way of organizing and managing public passenger transport.
