The GPS system has replaced the use of map to determine location on the road and route planning. Its development has also made it possible to use this technology for other purposes. On the basis of the satellite locator it is now possible to control the vehicles and guide them. This is particularly useful in fleet of service vehicles. The system also monitors driving style, fuel consumption, speed and many other parameters. All controls are carried out at a distance from a control centre. Companies gain productivity, efficiency and maximize their services on the field. Technology also helps us to increase traffic safety and reduces impact on the environment. Foreign companies have reported about good results which are comfirmed by the local surveys. The use of such systems in Slovenia is present a decade, but in recent years the demand is on the rise. The thesis focuses primarily on the experience of\ud
Slovenian companies. On the basis of the research, the actual savings and other positive effects achieved by using the system were described. Some are expressed as a percentage, the other merely indicative. Take into account the different characteristics of companies such as the number of vehicles, mileage, area of work. These may affect the results. The analysis shows when the system turns out to\ud
be the most effective and when it is less effective. The real savings are not always high but there are virtually no negative experiences
