Re: [OSRM-talk] Can hints be used to identify a common segment?
If points are not in order in the route, but are in the same segment, then forward_node_id, reverse_node_id and name_id for each phantom node must be identical. As you say, this information is already in hint_data (decriptors/json_descriptors.hpp). Best regards. Fernando.

Re: [OSRM-talk] Can hints be used to identify a common segment?
You can use DecodeFromBase64 in algorithms/object_encoder.hpp to decode the hints to a phantom_node_pair. Phantom nodes contain contain a forward_node_id and backward_node_id which you can use to determine if its the same segment.
