The system was designed by the Belgian . Bollen worked as a mine engineer from 1971 to 1990, and then joined
Regionaal Landschap Kempen en Maasland (RLKM). RLKM did not ask Bollen to design the scheme; he volunteered it. The idea of labelling each intersection was inspired by his annoyance at having to stop at each intersection to read the map, when out biking with his wife; he personally describes himself as more of a hiker than a biker. Rumours notwithstanding, the numbering was
not inspired by a wayfinding system from the mines, nor by the
London Underground. Bollen said in a 2017 interview that the choice was straight logic: he needed to label each intersection, and using town names would have
caused chaos, and there were not enough letters in the alphabet, so he used numbers. He wanted something short; he felt it was important that the signage not contain too much information. RLKM estimates that the network brings 16.5 million euros of revenue to Kempen (
Campine) in Maarsland annually. Bollen has said he was surprised by the system's success. The system won the Paul Mijksenaar Award for
functional design in 2013.
Areas The system was first introduced in the Netherlands in 1999, The system is displacing more traditional
national cycling route network signage: long, named routes, each individually signposted. In 2017–2021, the Netherlands reduced its
LF-routes, amalgamating some of them. The ways themselves remained part of the numbered-node network. ==Use==
