Dorsalys installs a carpooling device for APRR on the A48, approaching Grenoble
To improve traffic flow on the way into the city of Grenoble on the A48 motorway, APRR commissioned our Dorsalys experts to install a carpooling detection system. This device enables vehicles in a reserved lane and the number of occupants in each car to be identified and counted.
The carpool lane on the A48 is open only in the event of traffic congestion. It is reserved for vehicles carrying a minimum of two people, taxis, and vehicles with a "zero emission" Crit'air sticker (hydrogen or electric).
"At the entrance to Grenoble, we have installed and commissioned a device equipped with carpool detection sensors designed by the company Pryntec. These cameras can check that vehicles travelling in the reserved lane are authorized to do so. We have also commissioned signposts with variable information messages for users. This encourages offending motorists to change lanes if they are alone in their vehicle”, said Transport and Mobility Development manager Serge Balmonet.
The detection device and variable message signposts were connected to fibre-optics by our specialists and required civil engineering work for the concrete slab foundations as well as electrical work for the power supply and data transmission.
