12th International Scientific Conference, April 20-22, 2009 Brno, Czech Republic 73Fig. 1 Telematic SystemsTraffic data from telematic systems on motorways and expressways gets collected in theNational Traffic Information and Control Center (NDIC).There, team of operators works on 24/7 basis. The center receives traffic information andtraffic data, evaluates traffic situation, and verifies generated traffic information (usually, multiplesources are investigated). In short time to come, the center will be actually able to control the trafficusing powerful telematic systems.The NDIC features central control system that includes the following core modules:- Communication interface- Interface for telematic applications- Dispatcher supervision subsystem- Traffic control subsystem- Traffic and control information supply subsystem- System management subsystem- Traffic engineering applications- Uniform user interface for operatorsFig. 2 The NDIC resides in a modern building in Ostrava and features state-of-art technology.
7412th International Scientific Conference, April 20-22, 2009 Brno, Czech RepublicProcessed traffic information/data is sent using automatic/semiautomatic scenarios to variablemessage signs on the roads. The other channels include RDS-TMC radio broadcast, traffic portal(www.dopravniinfo.cz), XML Data distribution interface for radio/TV stations, telecommunicationoperators, internet service providers, GSM-based traffic information services, transporters, and soon. Traffic information and traffic data from the JSDI will be available within all primary sourceinformation systems, as well.Fig. 3 Camera system on D1 motorwayFig. 4 Traffic portal at www.dopravniinfo.czThe JSDI includes also the Central Road Registry and uniform geo-referenced Global networkof roads.References:Based on JSDI project information.
