Traffic management in Slovenia is divided between several operators, each of which, in accordance with legal principles and concession duties, manages a limited set of traffic data. To improve traffic management and unify the traffic information, a National Traffic Management Center (NCUP) has been established, which will be the central point for traffic management in Slovenia in 2022, performing some of its operational tasks already. Physically, the unification of road operators is already taking place in the premises in Dragomelj, where the major traffic control center of DARS d.d., the major traffic control center of the Directorate of the Republic of Slovenia for Infrastructure, Representatives of the Police and NCUP share common premises.

NCUP has established a digital data warehouse, where all current information on the state of traffic in the Republic of Slovenia is collected. Based on the collected data, traffic flow forecasts up to 1 hour in advance are made in real time with the help of the Dynamic Simulation Traffic Model (DSPM). DSPM is based on a previously developed macroscopic traffic model, which was developed for the entire territory of the Republic of Slovenia.

we’ll present the Slovenian National Access Point for traffic data with its public-facing part in form of a web page an B2B exchange services with metadata including its back-end systems and the stakeholders involved on the national level.
With the back-end systems, we’ll focus on one of the core systems needed to operate the National Traffic Management Centre (NTMC) which is a DATEXII compatible national data warehouse for traffic data with its real-time and historic data. We’ll also present some support services which range from simpler ones like national gazetteer and routing services to more complex ones like OpenLR encoding/decoding services, OpenAPI compatible local journey planner, and TN-ITS services.
All the data from this system it then available and exchanged through standard REST APIs with another level of back-end systems dealing with traffic flow and traffic modeling.
