The theme of this diploma thesis is system for fleet management. Systems for fleet management make modern way of doing business. Fleet management systems includes: tracking information, fleet maintenance costs, human resources, paperwork and goods being transported. Through the development of the automotive industry sensor systems today allow us to monitor all parts of a vehicle and they can work with external systems for tracking vehicles based on the collected data from vehicle sensors. Systems for fleet management can generate a wide range of information. The aim of introducing the system in companies is easier operation, faster adjustment to unexpected changes and to reduce operating costs. This diploma thesis shows the statistics of transport in the world and the European Union. On founded statistical data graphs of international and national transport within the EU countries are generated. All the elements of sensor systems and vehicle functions that the system provides to companies are described. The company Mobilisis Ltd. was selected as a good practice example. Functions that their system provides, hardware that the company is installing in vehicles and software they generate are described. As a result few graphs that are generated by their system are shown as an example.
