The application viaRODOS can be found at viarodos.cz. Information is updated every half minute.
Information is acquired primarily from 130 thousand referential cars, which are monitored by satellite systems. An expert from VŠB – Technical University of Ostrava Martin Hájek says: "We currently have a 6 to 7 percent coverage of traffic streams, which is sufficient to give quality information to drivers. It is actually one of the most accurate traffic monitoring systems in Europe."
Data from viaRODOS are already used by the National Traffic Information Centre as well as "Zelená vlna" of Czech Radio.
