Hi Bernhard,

I guess you mean ways that are tagged access=destination?

The attached patch fixes that case. It's too strict in that it will stop
all routing using the tagged way but I don't know how else to handle it.

hprof showed that quite a lot of time is going in Coord.distance(). The
orginal road name pois code used that method a lot to find the nearest
city to each road. So that will get improved when your more efficient code
is integrated.

Does it go any faster if you give the Java VM more memory?

Cheers,

Mark
