in PTv1, one relation is used for all forward and backward route. therefore ways that is in use only in one-way route must have forward/backward role.
in PTv2, the previous relation is splited in 2 relations. one with all ways used in forward, another with all way used in backward (and we group together with a route_master). therefore all way have a empty role (= no need to put all with forward, it's always the case in PTv2) yes maybe that should be better explain in the wiki Le 09. 01. 18 à 12:22, Fernando Trebien a écrit : > The article on route relations [1] doesn't make any distinction > between PT versions regarding those member roles.
