Jedná se o subsystémy sloužící ke sběru a vyhodnocení meteorologických dat (meteostanice a meteoserver) a ve spojení s PDZ METEO rovněž umožňují varování řidičů před nebezpečím náledí. Tyto systémy, které využívají mnozí správci pozemních komunikací (ŘSD, TSK, BKOM, SUS, apod.) umožňují:V zimním období monitorovat stav povětrnostních podmínek na sledovaném úseku komunikace (meteostanice…

Ovlivňování dopravy je dopravní funkce systému, která umožní prostřednictvím zařízení na komunikaci, konkrétně zařízením pro provozní informace (ZPI) a proměnným dopravním značením (PDZ) ovlivnit chování řidičů v případě různých mimořádných událostí. Toto téma neřeší samotný sběr dat či jejich zpracování a vyhodnocení v dopravním centru (to je předmětem jiných hesel), soustředí se na konkrétní…

DIŘC zaujímá v hierarchii ovlivňování dopravy nejvyšší pozici. Na úrovni ČR z pohledu hierarchie Dopravních center zaujímá nejvyšší úroveň - národní - NDIC (národní dopravně informační centrum), s kterým obousměrně komunikují oblastní či městská dopravní centra (např. HDŘÚ Praha, DIC Brno, SSÚD Rudná apod.). Další centra se postupně připravují.DIŘC je hardwarově a softwarově vybavený…
