SELECTION OF ITS SOLUTIONS FOR IMPROVING THE QUALITY OF THE TRAFFIC SYSTEM IN THE CITY OF ZAGREB BASED ON USER REQUIREMENTS

The quality of the transport system in cities is significantly improved using intelligent transport systems (ITS), which implies the use of advanced telematic solutions and other technologies. ITS can be defined as a holistic and information communication superstructure of the classic traffic and transport system, which can achieve a significant improvement in traffic flow, more efficient transport, increase in traffic safety, comfort and protection of passengers, less environmental pollution, etc. (Bošnjak, 2006). In the initial reference model for the ITS sector, 11 functional areas and 32 services were defined. Some of these functional areas are passenger information, traffic management, driver assistance and vehicle control. The implementation of intelligent solutions makes it possible to fulfil user requirements for a given system, such as the optimization of adaptive traffic light systems, the traffic management centre, the public transport (PT) passenger information system, giving unconditional priority to urgent services, the automatic payment system for entrance to the city centre, and the park & ride system
