Extrapolating, should I use oneway:residents=no on a one way road which has this exception for people living on that street? That *sounds* about right, but I'm curious how that works...is it honor system, or is there some kind of local permit system? Are visitors able to negotiate restrictions like residents, or do they have to go around? signature.asc Description: OpenPGP digital signature ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Have you read the proposal as well as the Extended conditions for access tags add-on proposal? Your argument would be valid if the only possible condition would be the type of vehicle. However, it's also possible to use current time, weather, lighting etc. as a condition. Oooh, that could be interesting to help make more ferry crossings on Oregon's Willamette River more precise... access:flooded=no access:night=no plus standard seasonal restriction tags make more sense than hourly ones. Plus could be very useful if your routing software is aware of river levels and daylight. signature.asc Description: OpenPGP digital signature ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

This would be especially handy in Portland, Oregon where some minor roads connecting major streets to bicycle boulevards occasionally have this situation, as well as provide some kind of warning in a spot where cyclists may not expect such an arrangement (one example would be how OR-99/I-5 connects to Jantzen Beach by bicycle, where cyclists leaving the cycleway for Jantzen Beach find themselves placed facing the wrong way on a freeway onramp, even if the correct way to handle this is slaughtering the civil engineer who thought up that half-baked interchange). signature.asc Description: OpenPGP digital signature ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

However, it's also possible to use current time, weather, lighting etc. as a condition. As most conditional access tags do not contain a vehicle class, the idea of defining the access rights of vehicle class x cannot apply to them. Instead, condition semantics are used: The base key (the first part of the key) applies if and only if all appended conditions are fulfilled in the situation at hand. So the way is normally an oneway street, but for people using a bicycle it isn't. This makes sense for other conditions than vehicle classes, too, and can be easily and logically extended to more than one condition (for example, maxspeed:hgv:wet for hgv maxspeed on wet roads). The xxx:oneway looks to be used a lot more often than oneway:xxx as well in current data I haven't seen a consistent definition using your way of tagging that works for more complex cases with multiple and non-vehicle conditions, though.
