Term Definition
"Small mileage" fare
A colloquial term for a preferential rate for residents who do not regularly use their cars, meaning they make only a small number of trips per month. Additional trips beyond this quota are charged individually. This system was implemented in Lyon under the name " Subscription Domicile " in 1998.
Tarification au poids
La tarification du stationnement en fonction du poids du véhicule est permise depuis 2019 par l'article L2333-87 du Code général des collectivités territoriales. Elle a été mise en œuvre à Paris, Lyon et Bordeaux, dans une logique de contenir l’essor des SUV et leur impact sur la qualité de vie urbaine. Les seuils sont plus élevés pour les véhicules électriques, en raison du poids de leurs batteries.
Tarification sociale
La tarification sociale / solidaire du stationnement a été permise par la loi d'orientation des mobilités du 24 décembre 2019 (LOM) qui a modifié l'article L2333-87 du Code général des collectivités territoriales. Le tarif « peut être réduit en fonction du niveau du revenu des usagers, de leur statut ou du nombre de personnes vivant au sein de leur foyer, en vue de favoriser l’égalité d’accès à la mobilité des personnes en situation de vulnérabilité économique ou sociale ». Le niveau de revenu (tranches 1 à 3 du quotient familial municipal) est souvent utilisé comme seuil pour les ayants droits.
