Abstract: The traffic system is expected to provide faster, safer, more reliable, more comfortable and less expensive movement with enabling of maximal personal mobility. One of the necessary preconditions to realize these expectations is the real-time information of all those participating in the traffic processes with all the relevant data. Consequently, it is necessary to design and construct a traffic system that will, with the application of advanced information communication technologies (ICT), insure the backbone that will integrate the users’ services based on the principles of intelligent transport systems (ITS), in order to be able to provide the system users with reliable, precise and timely information necessary for a more efficient realization of the transport process.
With the application of modern ICT, the system for traffic information management collects, performs the adaptation process, fusion and processing (verification and addition of weights to each collected information) and carries out the distribution to all the interested users. Thus, new services may be offered that directly contribute to the improvement of traffic system quality by improving the change of space – time (s, t) coordinates (Figure 1) of the transported entity which is transported or transferred in adequate transport entity and moves with it along the transport network, with better efficiency of the consumed energy and less polluted environment.
The application of terminal user equipment and the developed program package adapted to single users and terminal equipment, allows input of information on the events by the information source or their request for certain information. The system implies the implementation of services of advanced fix and mobile communication systems, and naturally the Internet. By implementing separate modules it will be possible to process different input information received by WEB provider, WAP protocol, E-mail and SMS/MMS messages and the so-called CALL centre. With the previously mentioned communication technologies, RDS-TMC technology for user information by means of radio receiver can be applied in the distribution of data.
The information service providers can use output data from the system for traffic data management and thus expand their activity or be exclusive suppliers of traffic information with or without added value. Based on this, with intermodal pre-travel and on-travel informing of the traffic system users, significant improvements can be achieved in dynamic vehicle fleet routing, forecasting of travel time, etc. Modern mobile communication systems offer services which allow realization of real-time informing of all the traffic system users, with the possibility of realizing financial profit of the system for traffic and transport information management (STTIM). Different business models of operation STTIM operation will attract a large number of those interested in performing this, until now in the Republic of Croatia (RH) unrecognized activity.
