the route description needs to be different for ways no names. as it is now, odd descriptions result:

1. Head on Njalsgade for 80 m
2. Turn right on for 89 m <--------------- odd grammar
3. You have reached your destination

i'm also noticing that turns from a way without a name, to another way without a name seems to be excluded altogether from the route description. for example this route description is output for route that in fact includes 3 turn (at path intersections):

1. Head on for 352 m
2. You have reached your destination

an idea could be to use the type of path in place of the name, for example: "turn right on cycleway", "turn left on footway", "continue on residential road", etc.
