One little point Untill now GPS navigation is orientative, not compulsory, obligatory or have-to-do. So instead your Osmand says you go in opposite direction, you drive, you decide. No kamikaze please.
yopaseopor PD: conditional lanes tagging situation would be interesting with a new tag (forward/backward/reversible), for example... lanes:forward=1 lanes:backward=1 lanes:reversible=1 reversible:forward=Mo-Su 07:00-09:00,15:30-17:30 reversible:backward=Mo-Su 9:00-15:30 reversible:closed=Mo-Su 17:30-07:00 On Thu, Nov 8, 2018 at 11:12 PM Richard <ricoz....@gmail.com> wrote: > On Thu, Nov 08, 2018 at 04:05:49PM -0500, Jack Burke wrote: > > > Following the KISS principle, barrier node tagging might be the way to > go, > > at least initially. > > > > Barrier tagging Pros: > > * Easy to implement in routing (e.g., OsmAnd's routing.xml can process a > > node as barrier=1 or barrier=-1 based on the opening_hours times). > > > note that OsmAnd doesn't do any time dependent routing, or at it least it > didn't do it for a very long time. > > > Barrier tagging Cons: > > * Having a hard time thinking of any. > > might work to some extent but I see it as important deficit that the > directionality > of the road isn't modelled.. sooner or later it will cause disaster. > Imagine routers > to issue commands like "turn around and follow the road in opposite > direction" when the > diver missed an exit for example. > Also, just one single entry point that someone has forgotten to tag with a > barrier > or has the wrong time information and the router will send kamikaze > drivers in the wrong > direction into the expressway. > > My thought would be to have a variable time dependent number of lanes in > each > direction. > > Or "oneway" with conditional restrictions > https://wiki.openstreetmap.org/wiki/Conditional_restrictions > > Richard > > _______________________________________________ > Tagging mailing list > Tagging@openstreetmap.org > https://lists.openstreetmap.org/listinfo/tagging >
