The initial activities of the company in the field of road transport were related to the development of light signalisation at cross-roads in Czechoslovakia during the 60´s of the last century. Since then AŽD Praha controllers have become a standard and hundreds of them were produced for Czech and Slovak cities. In the first place the microprocessor controller MR-1 has become a legend. In the process of production and development the company included gradually into its program the production of masts, signals, induction and tramway detectors and of other equipment related to the road transport. In 1993 the Division of Road Technology Automation (DAST) was set up. It is located in Brno and it concentrates all AŽD Praha road transport activities. Thereby a closed technology circle has been set up – own development, design, production and installation, service, consulting and commercial activities. For strategic reasons the company established within its Prague headquarter a commercial section for road telematics which is subordinated to DAST. The section has taken over all the commercial activities and the conception of the development of activities in the road transportation sector.
The division aims its activities, besides its traditional products (light signalization, controllers), primarily at the road telematics, progressive branch of the road transport (camera systems enabling recognizing of registration plates of the cars, tunnel, parking and monitoring systems).
