TN-ITS is concerned with the exchange of information on changes in static road attributes. Static meaning that the attributes are of a more or less permanent nature, even though they may sometimes change such as speed limits. The focus is in general on road attributes based on regulations, but may extend to other road and transport related features.
It is important that digital maps for ITS are highly up to date for attributes that are critical in terms of safety and efficiency. The map providers cannot easily keep their maps up to date for such attributes, while up-to-date maps are a key asset for ITS applications.
The solution is to retrieve the information on changes from the road authorities. As they create the changes, they are the most efficient and immediate source for such information. This requires digital storage and maintenance on the side of road authorities, and some kind of flagging of changes. With governments going more and more digital, systems for such digital storage and maintenance are increasingly available. However, with a multitude of solutions that are different in terms of GIS and data models applied. Therefore a common exchange format is needed, enabling creation of plugins to existing (legacy) systems for extraction of information on changes in road attributes. Immediate updates from authorities to map makers only make sense if the second half of data chain from map makers to end user devices will also be in place. The good news is that substantial progress on incremental updating to the end user is being reported by the map makers.
The following data is available for the users:
Permanent speed limits managed by Hungarian Public Roads. It might be the general speed limit defined by Road Traffic Regulation or lower.
Information on signs placed at roads managed by Hungarian Public Roads.
Permanent access restrictions and other traffic regulations.
Vehicular restrictions and regulations.
Parking information (Location of parking places, service areas and availability information).
Location of public transport stops and interchange points.
The operator of the portal and the TN-ITS service is the Hungarian Public Road Nonprofit PLC.
The company was established on the 1st of October of 2005. With regard to its 5300 employees and economic indicators, the Hungarian Public Road Nonprofit PLC stays within the first ten state-owned enterprises in Hungary. Road operations are carried out in 19 counties, at 93 engineering sites, managed by the headquarters in Budapest.
The activities of the Hungarian Public Road Nonprofit PLC consist of the operation, as well as the routine and the preventive maintenance of the national public road network, including expressways and motorways. In addition to that, our Company is responsible for the issuance of rout permits for oversized vehicles, the control of trucks at weight control stations, the provision of trainings for professionals within the entire road sector and the operation of the Road User Information Services, the National Road Databank and the Road Museum in the municipality of Kiskőrös.
Besides preforming its duties under contract, the Hungarian Public Road Nonprofit PLC is also committed to social responsibility, the education of the new generations of road users for environmentally responsible behavior, as well as to the improvement of traffic ethics and safety.
The data providers of TN-ITS database are going to be the followings:
The database will store only the data of Hungarian Public Road until the end of the pilot phase.
The purpose of the document set is to give an overview of the steps necessary to implement a TN-ITS compliant data exchange and to provide reading instructions of the TN-ITS documentation relevant to receiving changes from the service and their transformation to the receiver's data store.
The role of the data sender is normally held by an enacting authority (i.e. the entity responsible for supervising the establishment of laws and regulations for transport and traffic), whereas the role of the data receiver can be held by any party using road data in applications (e.g. providing maps and data sets for use in ADAS and ITS applications).
