The activists last year received more than 300 complaints after launching a similar call, forwarding the information to communes and the transport ministry to highlight areas where cyclists are at risk.

“National cycleways are not always fit for cycling. Some tracks are simply missing and numerous existing cycleways present serious weaknesses in terms of biking safety,” the group said.

It has now taken the initiative online, creating a where users can register interrupted or missing cycling paths, potholes and damaged surfacing, missing road signs or dangerous crossings. Users can submit photos or videos of the locations together with their suggestions for improvement.

The map--available in English, French and German--will be online until 31 October and the information collected will once again be forwarded to authorities in charge of Luxembourg’s roads. It will also be made available to the public in mid-November.
