Motorways in the Republic of Croatia are equipped with the most modern systems for managing and controlling traffic. Monitoring and traffic management system on motorways are carried out constantly 24 hours a day from the maintenance and traffic control centers that are located along the individual motorway sections. Motorway traffic control centers, using modern Intelligent Transport Systems, constantly and in real-time monitor the state of the motorways and warn and prepare motorway users for all the extraordinary situations that motorway users might encounter. Using the camera and the video surveillance system deployed by motorways, operators have an insight into the current state of the motorway section, primarily by means of a traffic accident detection camera, driving in the opposite direction, traffic jam, etc. Numerous meteorological stations along the highway also collect and process data related to weather conditions on the highway and using these data to warn motorway users of weather conditions expected on a motorway. In this paper, the information management system on motorways is described using graphs. The graph theory allows displaying the flow of information essential to increase security and to address emission and congestion issues. The flow of information between the sensor system on one side, and the operator in the maintenance and control centers on the other, and the variable traffic signs system on the third side is represented by graphs. Timely information of traffic participants on changing meteorological conditions through variable signs is crucial to ensure safe traffic on motorways.
