It was broken into 13 operating companies, plus two specializing in auxiliary activities, all of them opting for the public enterprise status. Twelve are bus companies, owned by individual cities. In some cities, MTCs were restructured to separate the regulatory and operational functions. Wroclaw, Gdynia, and Bialystok have advanced the farthest in this, but the process is also underway in Warsaw and elsewhere. The Authority defines the route network, service standards and fares, checks compliance with service agreements, and does long-range planning.
Institutional design differs from one city to another.
In Warsaw, the new Mass Transport Authority, exists in parallel with a Road and Traffic Authority, newly taken from the Warsaw regional government. In Gdynia, the regional government has maintained its jurisdiction over roads. Wroclaw, in by far the most ambitious and advanced effort, has created one Urban Transport Authority, which combines mass transport, road and traffic matters, with the full scope of short and long-term responsibilities. With the new plethora of transport operators, division of the regional service network among the successor companies, the coordination of services and fare systems for inter-city routes, and the division of revenues all became problematic. This gave birth to Transport Associations, some of which follow the transit federation concept and others function much more like transport authorities in other cities.
