Da: Mark Burton <markb@ordern.com> Oggetto: [mkgmap-dev] [PATCH v1] - beware of the bollards! A: mkgmap-dev@lists.mkgmap.org.uk Data: Martedì 7 luglio 2009, 15:30
Fed up of being routed in your car down city streets only to find the way is blocked by a bollard? Well, if so, this is the patch for you.
If a way has a bollard on a point, the segments of the way that connect to the bollard have access restrictions placed on them. By default, a bollard implies: access=no, foot=yes, bicycle=yes.
Testing using mapsource shows that it generally works as expected although if the destination cannot be reached by any other route, it routes straight through the bollard rather than failing! If the destination can be reached by some other route, even if the route is really long, it will avoid the bollard.
I have chosen Garmin code 0x660f (pillar) for the bollard. On my etrex it appears as a small dot in the way.
As usual, all feedback is welcome.
Mark, I read on wiki that cycle_barrier has no "default" access rule. I think you should be more conservative and, in absence of explicit tags, let bicycles passing through (wiki says that cycle_barrier should only imply motor_vehicle=no) Ciao.
Cheers,
Mark
