Abstract
Urban public transport is one of the public services of great importance for the functioning of cities. Efficient and accessible public transport ensures residents’ mobility, impedes traffic growth and reduces the negative impact of transport on the environment. Progressing urbanization processes are the reason why large cities work together with adjacent municipalities to create supra-local structures and associations in order to provide public transport services. An example of such a solution is the metropolitan union in the Silesian voivodship. The paper presents the basic data characterizing 41 municipalities of the metropolitan union created in the Silesian voivodship, a starting point for further research on integration, transport offer and financing of transport services in the area of the created association.
