Tag defining to which vehicles this duration and distance matrix applies. If empty, this applies to all vehicles, and there can only be a single matrix. Each vehicle start must match exactly one matrix, i.e. exactly one of their start_tags field must match the vehicle_start_tag of a matrix (and of that matrix only). All matrices must have a different vehicle_start_tag.
