TN-ITS specification intent is support of continual exchange of ITS related static spatial road network data in established service chain from road operators to road map users.
TN-ITS platform (https://tn-its.eu/) supports EU member states implementation by providing guidelines, tools and services. In addition, TN-ITS platform is working on standardisation by defining and maintaining the TN-ITS specification in the CEN/TC278/WG7 framework that resulted in standard ISO 14823:2017 “Intelligent transport systems - Graphic data dictionary”.
Pilot TN-ITS GO service area covers motorway network in Slovenia. Location referencing methods applied are:
- GML
- OpenLR
- INSPIRE National Linear Location Referencing
Vertical traffic signalisation is included according to standard ISO 14823:2017 “Intelligent transport systems - Graphic data dictionary” and general national legislative for truck traffic during the weekends and holidays.
TN-ITS discovery and download services are implemented with the REST API.
Pilot service TN-ITS GO was implemented by AVP (Slovenian Traffic Safety Agency https://www.avp-rs.si/en/) and transferred the results to NCUP (National Traffic Management Centre) for the deployment, maintenance and publishing at National Access Point for traffic data and information (https://www.ncup.si/en).
