hmm normally this should be documented in the responses tab of the interactive documentation. I will have to fix that.
this i the documentation for the values array of any requested extra information:
A list of values representing a section of the route. The individual values are: Value 1: Indice of the staring point of the geometry for this section, Value 2: Indice of the end point of the geoemetry for this sections, Value 3: [Value](https://github.com/GIScience/openrouteservice-docs#routing-response) assigned to this section.
So these represent segments of the route that have the value you can derive from the tables at the ors-docs readme.
waytypes: {'values':[[startPointFirstSegment, endPointFirstSegment, waytype value],[startPointSecondSegment ...
You will have to decode the geometry to extract the exact points or use the geojson endpoint.
best regards
