*Also the presence of shops and pubs may in some context indicate the principal road. *
Depend of contexte because if this is a living_street I not sure that is a good idea to set this as principal road for vehicule... This is why there is a global contexte and others distinctives properties usages Graph can't be the same for all type of users. Default graph is for biggest usage. In general for standard vehicle... I explain in french list why you don't cut a major (primary, secondary, tertairy) road by a living_street because that have an impact on routing graph... So I Think it's necessary to explain why primary, secondary, tertiary is also used because users don't respect the abstraction schema just because there is a signalisation on the spot (for exemple living strret with 50m size) The explanation is "Opentreetmap store the real life, or store what I can see" I understand @Paul Allen message The UK has four official, government-assigned classifications of through roads: primary (A roads), secondary (B roads), tertiary (C roads) and quaternary (U roads, where U unfortunately stands for "unclassified" which some mappers misinterpret as meaning "uncategorized"). There are also motorways (level 0 in the 1-4 hierarchy) and trunk roads (level 0.5 in the 1-4 hierarchy). There is same official comportment in FR but ther is a ideology who would like set it on city only base with the density of traffic, size of road or/and speed or/and low For me this is a spiderweb to redirect A > B with panel direction to Country,Region city, Departement city, Major sub departemental city and other In big town there is same problem to redict trafic to borough <https://wiki.openstreetmap.org/wiki/Tag%3Aplace%3Dborough>,suburb <https://wiki.openstreetmap.org/wiki/Tag%3Aplace%3Dsuburb>, quarter <https://wiki.openstreetmap.org/wiki/Tag%3Aplace%3Dquarter>, When GPS didn't exist there is only traffic_signs and you set a road map with place direction. Road in neighbourhood is for me globaly residential exept in plot because this is highway=service+service =alley or service=driveway Cheers Jérôme Le mer. 7 août 2019 à 14:48, Martin Koppenhoefer <dieterdre...@gmail.com> a écrit : > > > sent from a phone > > > On 7.
