New section control speed cameras have been installed in the tunnels of the A7.
The devices have been installed in the Grouft tunnel (southbound>northbound) and Stafelter tunnel (both directions). In addition to these two tunnels, Minister for Mobility François Bausch confirmed in July that a speed camera will also be installed this year in the Gousselerbierg tunnel. This represents an investment of €1.7 million to equip the three tunnels.
According to Bausch, 115 accidents have occurred in the A7 tunnels since 2015.
Unlike other motorway sections, where you can drive at 130 km/h, the speed limit in the tunnels is 90 km/h. On the A13, this difference has already resulted in thousands of tickets for motorists in a hurry. These are “staggering” figures for the head of road safety, who readily admits that few motorists slow down to drive through tunnels.
Contrary to the “classic” speed camera, section control speed cameras measure the average speed on a given portion of road.
To do this, the speed camera takes measurements at the entrance and exit of the targeted section as well as a photo of the vehicle. The average time taken to cover it will then determine the speed of the route. If the speed limit is exceeded, the offence will be recorded at the point of “exit” from the section.
Like other speed cameras, the “section” model has a tolerance: 3 km/h between 25 and 100 km/h, 3% above that.
