The National Data Warehouse for Traffic Information explained

The Netherlands is working hard on improving mobility. Construction of new roads and the pricing of mobility are effective long-term measures. In the short term a more effective use of existing roads will be the best way to improve traffic flow. Traffic management by road authorities and reliable traffic information for road users can result in fewer traffic jams and delays within just a few years.

A requirement essential to achieving this objective is to know the traffic situation on all motorways and major provincial and city roads at all times. To achieve this, a National Data Warehouse for Traffic Information (NDW) is being created in the Netherlands. NDW will provide complete, reliable and up-to-the-minute information on the status of the basic Dutch road network. This combined investment by 15 authorities is expected to have major social benefits.
