National Automatic Toll Collection System for motorways, expressways and other roads

Th e paper refers to some problems of European Electronic Tolling Service (EETS) implementation in Poland. Motor Transport Institute has developed the structure of the National Automatic Toll Collection System (NATCS). It consists of National Automatic Toll Collection Centre (NATCC), OBU and control subsystem. NATCS system is based on a combination of mobile communications using the GSM-GPRS standard technology, the satellite-based global positioning system (GPS) and 5,8 GHz microwave technology. An innovative element of NATCS is the On-Board Unit (OBU), which automatically calculates the amount of charge due taking into account the vehicle category (admissible weight, number of axles), road distance and the emissions class (ecological aspect). The control subsystem distinguishes between automatic enforcement through control gates, enforcement by mobile teams, and patrol teams. Th is presented kind of system is the best toll solution for Poland because of unique capabilities.
