Norway – Vehicle-counting machines – Framework agreement for the purchase of traffic registration equipment for motor vehicles at fixed stations.

The contracting authority would like tenders for a framework agreement for the purchase of traffic registration equipment for motor vehicles at fixed stations. The Norwegian Public Roads Administration is responsible for collecting road traffic data (further called traffic data) on most european and all national roads in Norway. Nye veier, the counties and municipalities are responsible for collecting traffic data for the other roads. Traffic data will be used, among other things, for traffic management, operation and planning of roads. The Norwegian Public Roads Administration has developed a separate system called the 'Traffic Data System' for the collection, processing and publication of traffic data. Depending on the type of traffic registration equipment (desktop or mobile), data is collected in different ways. Data loggers that are at fixed stations with continuous registration, are connected directly to the traffic data system in a closed network. The communication between the data loggers and the traffic data system takes place over OPCUA. Data from stationary continual stations is retrieved with just a few seconds delay.
