Stanice ITS je základním stavebním blokem komunikací ITS (dříve CALM). Různé konfigurace stanice ITS jsou využívány ve vozidlech a na infrastruktuře a umožňují komunikaci vozidlo-vozidlo, vozidlo-infrastruktura a infrastruktura-infrastruktura. Komunikace jednotek ITS probíhá na bázi různých komunikačních protokolů v závislosti na jejich aktuální dostupnosti, požadované šířce pásma, latenci a…

Systém plovoucích vozidel využívá online data z vozidel jedoucích na silniční síti. Data jsou přenášena bezdrátovou komunikační sítí do centrálního databázového serveru, kde jsou zpracovávána. Data z plovoucích vozidel představují obvykle komplementární doplněk k datům změřených z čidel na infrastruktuře. Data lze využít pro nejrůznější aplikace pro sledování dopravního proudu…

Stanice ITS podporuje celou řadu komunikačních protokolů. Komunikační protokoly, mezi kterými stanice ITS automaticky volí na základě nastavených priorit, umožňující komunikaci na krátkou i velkou vzdálenost.

Zveřejňování služeb stanice ITS je systém, který slouží k informování ostatních ITS stanic o dostupnosti služby, kterou daná ITS stanice nabízí. K tomu zveřejňování je využit protokol FSAP (Fast Service Advertisment Protocol). Služby stanice ITS pak využívají navazující aplikace, které mají regulovaný systém vývoje, instalace, registrace a testování.

Architektura komunikace ITS (CALM - Komunikační infrastruktura pro pozemní mobilní zařízení, dále v textu jen CALM) definuje obecný nadstavbový komunikační protokol, určený pro vzájemnou výměnu dat mezi vozidly a infrastrukturou. CALM sdružuje všechny možné typy existujících komunikačních médií do jednoho celku. V zásadě lze rozlišit tři základní typy komunikace a to vozidlo-vozidlo,…

NOTE 1 to entry: Within the US, the National Transportation Communications for ITS Protocol (NTCIP) standards identify an “information layer” on top of the traditional OSI stack. However, the purpose of this layer includes both information configuration and functionality. The ITS-S reference architecture separates these two roles between the management entity and the application entity.
