What has been achieved so far?

The Amsterdam Practical Trial (APT) has carried out large-scale practical tests on integrating innovative systems in vehicles and on roads. The conclusions, lessons and outcomes of the tests that were carried out up to 2016 are below.


  • Better management opportunities and new services for road users have been enabled.
  • Great strides have been made towards the Integration of roadside and in-car systems.
  • By testing of innovative concepts, the roll-out of these concepts is possible; the cost-effectiveness of integrated network-wide traffic management can be increased and opportunities for new markets are created.

Lessons learnt

  • Solid asset management is an essential precondition.
  • Monitoring and measuring are key.
  • Open data is crucial.
  • TSSs and RMSs are more effective due to coordination and automation.
  • APT’s Integrated network-wide traffic management concept is applicable elsewhere.
  • Individualised in-car route and travel information is possible.
  • Use of social media has added value.
  • A great demand for pre-trip information exists.
  • Linking public and private network management provides a greater number of opportunities.
  • Well-organised public-private collaboration creates new management possibilities.
