Traffic is an activity related to everyday life and production, whose task is to transport people and goods from one place to another. Due to crowds in traffic, in more developed parts of the world, drivers and passengers in cars spend billions of hours and spend tens of billions of dollars a year. For traffic congestion, solutions are mainly found through projects based on the use of computer systems and simulations of different traffic situations, that is, in combining IT and traffic infrastructure. Using modern information technologies, it is encouraging the establishment of a new infrastructure consisting of networks of roads, railways, airports, stations and ports connected to systems based on the Internet. Future solutions will be based on the use of smarter and environmentally sound vehicles and their connection with infrastructure facilities, such as gas stations, parking lots, garages, etc. The wider application of advanced information technologies, besides communication with vehicles with infrastructure, will also enable communication of vehicles. At the beginning of the 21st century, traffic experts agree that successful solving of the growing problems of traffic and transport is no longer possible without the application of the complete concept and technologies of ITS (Intelligent Transport Systems).
