TropKM is a project of the Regional Government of Mazowiecki aimed at the development of innovative solutions to the problems of passenger transport in the regions affected by demographic change. The main objective of the project is to provide solutions to the problems of passenger transport, which are caused by the fact that individual means of transport are becoming increasingly dependent on public transport. This project will allow you to find out the potential delays and other problems caused by public transport in the regions affected by demographic change, which is a project of great importance. It will be possible to find out the data on the Internet, which will allow you to find the information quickly. The data is collected with the use of a GPS receiver and processed in a way that will allow you to find out the information quickly and easily.
