From the end of the eighties, when the idea of identifying the vehicle as a means of toll collection was first commercially realized, later known as electronic toll collection, to this day, the requirements of toll collection systems are significantly changed.
First of all, car traffic on roads, bridges, tunnels, and particularly in the cities has significantly increased compared to a period of thirty years ago. Increased number of vehicles has been enormous throughout Europe and the Western world, but particularly in the most populated parts of the world such as India, China, Brazil and all of Africa.
In addition to the number of vehicles, the variety of vehicles that may occur in the collection system has expanded significantly. Both in their external dimensions and shapes, and in the way how they use the highway. Thus, in India on the highway tractor or three-wheeler crowded with passengers may appear. On the other hand, in Europe, it is expected high throughput of vehicles, fast circulation of information, flexibility in pricing policy and high integration of the system both internally between its components as well as to external systems such as for example accounting system, ERP or central transport system. For vehicles using the highway and billing system it is no longer sufficient to determine only input and output location and class of vehicles. Already significantly have expanded the options of using different types of media such as smart cards, electronic RFID or DSRC TAG's different suppliers, different types of media using magnetic or barcode format. There are also various types of system users - standard users who pay the toll in cash, seasonal users, frequent motorway users and frequent local transporters who expect certain discounts. The goal of the concessionaire, the state and local governments is to increase the number of users of the highway by adjusting prices and reduce evasion of tolls by drivers driving around the roads. Therefore, along with good quality and efficient process of automatic detection, identification and classification of vehicles and toll, it is extremely important to have a quality network of sales locations and an elaborate system of planning and adjustment of price.
Because of these changes, the demands and expectations of road concessionaires who use toll collection system to collect their service have increased, but also the expectations of the drivers have increased.
