What is the advantage of the NDW Viewer for road authorities?

The NDW Viewer shows you all the latest information on a single map. This makes it easier to make quick decisions, detect incidents and assess traffic measures.

Which data streams are available?

Various data streams are available, such as DRIP texts, file information, travel times, traffic intensities, speeds, roadworks, bridge openings, matrix signs, Waze reports and car parks. In addition, more and more sources are being added.

Can the NDW Viewer also be used outside office hours?

Yes. Traffic control centres often use the NDW Viewer when it is quiet, such as at night and at weekends.

Can you also look back in time?

Yes. Through a link to the historical database Dexter, you can also consult past data via the map, for example for analyses.

Who develops and manages the NDW Viewer?

The NDW Real-Time team works on improvements every day. They do so under the leadership of the product owner. In doing so, they listen carefully to user feedback.

Can I give feedback as a user?

Yes. Feedback can be sent to the theme manager and/or the service desk.
