major roads have been built throughout the country. These together with a further 250 fixed cameras is to enable a levy of an eco tax on lorries over 3.5 tonnes.

Germany On 11 March 2008, the Federal Constitutional Court of Germany ruled that some areas of the laws permitting the use of automated number plate recognition systems in Germany violated the right to privacy. More specifically, the court found that the retention of any sort of information (i.e., number plate data) which was not for any pre-destined use (e.g., for use tracking suspected terrorists or for enforcement of speeding laws) was in violation of German law. These systems were provided by Jenoptik Robot GmbH, and called TraffiCapture. Hungary In 2012 a state consortium was formed among the Hungarian Ministry of Interior, the National Police Headquarters and the Central Commission of Public Administration and Electronic Services with the aim to install and operate a unified intelligent transportation system (ITS) with nationwide coverage by the end of 2015. Within the system, 160 portable traffic enforcement and data-gathering units and 365 permanent gantry installations were brought online with ANPR, speed detection, imaging and statistical capabilities. Since all the data points are connected to a centrally located ITS, each member of the consortium is able to separately utilize its range of administrative and enforcement activities, such as remote vehicle registration and insurance verification, speed, lane and traffic light enforcement and wanted or stolen vehicle interception among others. Several Hungarian auxiliary police units also use a system called Matrix Police in cooperation with the police. It consists of a portable computer equipped with a web camera that scans the stolen car database using automatic number-plate recognition. The system is installed on the dashboard of selected patrol vehicles (PDA-based hand-held versions also exist) and is mainly used to control the license plate of parking cars. As the Auxiliary Police do not have the authority to order moving vehicles to stop, if a stolen car is found, the formal police is informed.
