Description
When e.g. a footpath crosses a road there will be a tower-node for this junction. If u-turn costs are set to a finite value this means that the shortest path can include a u-turn at this junction, even if its not really a junction for the current vehicle (e.g. car).
Avoiding such u-turns would most likely be an improvement, but there can still be u-turns at 'real' junctions that aren't desired either.
