  • Analyse measurement data from viasis speed displays
  • Process data from viacount traffic counters
  • Process data from viafalcon radar detectors

Customised software for traffic analysis

Our development team is continuously working to further develop viagraph software, which analyses and evaluates a wide range of road traffic data. User-defined settings allow the software to be customised, simplifying day-to-day work with our products. Should you be interested in this custom-made solution, via traffic controlling has just the tool to help you analyse road traffic data.

Analysis data presented graphically in an easily comprehensible form

Local authorities, traffic planners and traffic statisticians not only need fast access to traffic data, they also need to have the data presented graphically in an easily comprehensible form. Excel-based graphs allow data to be reused in traffic reports, and additional road planning measures to be taken.

Whether as pie chart or bar diagram, as table or graph – there are many forms of presentation that are suited to visualising traffic data clearly and intelligibly.
