Within the solution of the Connect EU project, also the RDS-TMC traffic info broadcast in the areas and on the roads along the borders with Germany and Austria was tested. The user thus had the opportunity to get the information about traffic accidents and other incidents on the main backbone communication in the neighbouring countries while still in the Czech Republic (the navigation must contain maps containing the location code tables of both countries).
The RDS-TMC broadcast within the ITIS is done using the highest quality and most widespread software by GEWI, a company seated in Germany that has representation in Europe, Asia, and North America. Most of the RDS-TMC services not only in Europe are broadcast using this SW.
The JCDI-CRO (ITIS) service is continuously monitored and the broadcast is optimised technically and technologically as a part of continuous control and research activities. Together with experts, we look for the optimum broadcast settings to achieve the best possible traffic information reception via the service for as many receiver types available on the market as possible.
The ITIS operator has no influence over the quality and content of the information and bears no liability for the other nationwide RDS-TMC service, available under identification CRo_a_GA.
The special RDS-TMC service for our capital is broadcast from the Traffic Information Centre of the Capital City of Prague (operated by the Technical Road Management of the Capital City of Prague) on the frequency of Czech Radio Regina - Prague 92.6.
