[mkgmap-dev] [PATCH v1] - beware of the bollards!

Tue Jul 7 14:30:56 BST 2009

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.

Cheers,

Mark
