Marco,
I still do not see the reason to make 2 unaccessible arcs on both sides instead of one.
Imagine that you have only one restricted arc that is on one side of the bollard. Now if you are within that region and try to route to a point that is on the other side of the bollard, it will route straight through the bollard because you are leaving the restricted area and not entering it. If you have two restricted areas, one each side of the bollard and your starting point is within one of the areas, it will now not route through the bollard if the destination is outside of the restricted area on the other side of the bollard.
As previously mentioned, the case where both start and destination are within the restricted area does not work right and, currently, I don't have a plan for fixing this. I can't see how that can be achieved.
Hi Mark! Is there any chance for this patch to get committed in the near future? I think it would be very helpful for routing (also with barrier=cycle_barrier/gate/lift_gate etc) and the case of target and/or destination being too close to the barrier is not that common. Thank you for any info! -Martin
