It's nothing special. They are using standard garmin tools AFAICanTell. They learned from our maps that proper bicycle/topo maps will only provide good routing if preference is given in general for bicycleroutes. The autorouting is pretty good for cyclists, however because of 2 reasons: 1. their

Hi list, hi Mark, First, a remark. Since the oneway=yes/cycleway=opposite roads have (cycleway) attached to their names, a GPS unit will randomly show either the regular name, or the (cycleway) name. Which isn't too bad for testing, I'd suggest you leave it this way until we're set and done with

Hi V, Yes, using mapsource, if the cycleway=opposite tag is present it will route a car into the last segment of Hembrugstraat using the cycleway but if the destination is not the last segment of that road or the cycleway tag is not present, it will route the car correctly. Experimentally, I

I think the condition precedent you're thinking about is wrong here. The name that shows up in the routing does not have to be the street that is routed on. At least I see that behaviour quite frequently. How can I be sure? I use many non routable overlays and they have different naming.

Hi Mark, Without the all-cycleways option, it behaves normally. There must be some sort of Garmin rule in action here. I'll check if there's a better way (haha) to build the cycleway. Valentijn ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk

Mark, I've tried a couple of different methods to build opposite-cycleways, namely forbid all motoring traffic, make a real cycleway, but all of them make the Garmin turn to the last part of the oneway Hembrugstraat. So I conclude it's a Garmin issue. I'm sure we could come up with all sorts of

Mark, I think the following could be what happens. The GPS unit tries to route you to $dest, which is on a non accessible road. As non accessible has no access, it makes no sense trying other directions. If there's a crossing, that's a reason to try other directions so the oneway street will
