Central system technology

In April 2013 the DÜRR Austria was assigned to install the whole system technology of the traffic control system in Linz, which covers the geographic area of the A1 West motorway, A7 Mühlkreis motorway, A8 Innkreis motorway and A25 Welser motorway. The range of services not only included the distribution of energy, traffic management systems, traffic data collection, video surveillance and ERT systems, but also the field data collection, transfer and processing of information.
