Public transport in the city of Poznań is organized by Zarząd Transportu Miejskiego (ZTM) - Urban Transport Authority. ZTM is responsible for determining the transport lines, location of stops, distribution of tickets, ticket inspection and promotion of public transport.
The network managed by ZTM is limited to the area of the city of Poznań, with a few lines crossing the city boundaries. 4 operators provide services to ZTM, including the biggest one, i.e. MPK w Poznaniu Sp. z o. o. (Urban Transport Company in Poznań). ZTM tickets are valid only on the lines managed by ZTM. Other bus lines, as well as railway services, do not belong to the transport system managed by ZTM and require separate tickets.
The public transport system in Poznań consists of tram and bus networks.
Tram network plays an important role in the public transport system. The city policy assumes that the city center is operated only by trams. Car access to certain streets is restricted. There are 19 normal tram lines (numbered 1-20) and one night tram line (201).

The Poznań public transport with its network, timetables and tariff is unique in Poland. Trams are the core of the system - most of lines go with a frequency of 10 minutes. Bus lines play a complementary role to the tram network. This solution encourage passengers to change, offering high frequency connections with changes, instead of low frequency direct connections. It also makes the network less extensive and complicated to passengers.
Short-term and long-term tickets enable unlimited changes, but what about occasional travel? Poznań was the first Polish city which introduced time tickets. They are essential in the system, because, after punching it, the time-ticket holder is allowed to travel within the time specified on the ticket using different bus or tram lines within the ZTM network. Single-ride tickets are valid only in the vehicle in which they are punched.
