Hi, Andrew, The documentation says “The results are network distance, i.e. travel-time, in 10th of seconds.” It’s hard to translate that into distances without the speeds assigned to road segments. If one knows the type of road and what the “common” speed is for that type of road one can make an estimate, but it could still be quite far off. Do you have any guidance on how to get road segment information? If one needs to download the road data itself, then the length of the segments should be there, too.
