As had previously been announced, speed regulation measures are being put in place during the morning rush hour from 3 June at 6.15 am.

The trial of these speed limit changes is one of the planned measures to improve the traffic flow around Luxembourg.

The test phase for speed regulation on the A6 and A1 during the morning rush hour will be put in place from the Belgian border to Kirchberg from this Monday until 12 July.

The idea was presented in the context of the creation of a future carpooling lane.

By reducing the maximum speed limit from 130 km/h to 90 km/h, traffic during rush hour should flow better and the traffic jam situation should improve, argued the Bridges and roads authority.

Speed regulation measures will be in place Monday to Friday from 6.15 am to 9.15 am, excluding school holidays and bank holidays. Areas affected by road accidents or similar issues and require additional traffic management measures are excluded from the new regulation.

The morning speed limit, which will be applied on a total distance of 28 km, is shown on dynamic CITA road signs.

The speed regulation measures are monitored by law enforcement agencies.

How does it work?

It may seem strange to reduce the authorised speed limit in order to get to places more quickly. However, this regulation measure has been proven to work and applies the principles of fluid physics. The effort everyone makes by accepting to reduce their speed a bit slows down the creation of traffic jams and shortens the commute time for everyone.

Similarly, dynamic speed regulation takes real time traffic conditions into account and allows for instant reaction to adapt to the traffic conditions and to avoid traffic jams and to optimise flow management.

For the affected roads, dynamic regulation has not been retained, as traffic density is inevitably going to be high during the morning rush hour.
