The ratio of extended cycling infrastructure to public roads is an indicator of road coverage by cycling infrastructure. The extended cycling infrastructure used in the numerator included: cycle tracks, cycle and pedestrian tracks, cycle lanes, limited access roads, bus lanes and cycle streets. The length of the road network used in the denominator was calculated by adding main roads and local roads. The local roads were selected using the following tags: residential, living street, unclassified.

The ratio is an alternative estimate of completeness of the cycle network. In this case, we not only consider segregation on main roads, but also whether the local roads are developed to cycle-friendly standards.

Si internet était un pays, il serait le troisième plus gros consommateur d'énergie de la planète, d'après Greenpeace, derrière les États-Unis et la Chine. Car pour fonctionner, la toile a besoin d'infrastructures colossales : câbles sous-marins, data centers et serveurs par millions.
