UNE-CEN ISO/TS 17429:2017

This international standard falls into the Cooperative ITS set of standards based onthe ITS station reference architecture. Typically, raw and dense information transmitted by ITS stations (e.g. CAM and DENM broadcast from vehicles for road safety purposes) is collected by other ITS stations (presumably the roadside infrastructure ). This information must be processed and transferred in a standardized way between ITS stations (presumably between the roadside infrastructure and traffic control centres) so that it could be used for traffic management purposes by road operators. The processing of this information could also lead to improved road safety, improved road efficiency and reducedgreenhouse gas emissions. The purpose of this international standard is to specify the profiles for processing the collected information at the receiving ITS station and transferring the processed data to other ITS stations for applications related to transport infrastructure management, control and guidance. This standard will thus:- select the services, functions and expected results,- select the roles and responsibilities of all the involved actors,- select involved functions and SAPs (Service Access Point) of the ITS stationreference architecture,- characterize how the collected data is pre-processed by the receiving ITS station,- select the content of the information to be exchanged between the variousactors,- characterize the level of performance (best effort or real-time, etc.), confidenceand security (authentication, encryption, etc.) for the transfer of the information,- select the means by which the processed information is transferred (securely)between the different actors.
