PSA: upcoming OSRM version is going to announce mode

[DennisOSRM]

We just merged a larger change into OSRM that's going to support mode indication, e.g. it's going to announce when you have take a ferry with the car or perhaps a shuttle train.

The last entry in the instruction array indicate the mode by ID.

    "route_instructions": [
        [
            "10",
            "Kemberger Straße",
            418,
            0,
            41,
            "418m",
            "SW",
            217,
            1 <--- this guy
        ],...

For car directions, we have:

• 1 drive (99.9% of the time)
• 2 ferry
• 3 shuttle train

Up to 16 modes per profile are supported and 15 are available to the user. Mode 0 is used internally to indicate that a (direction of a) road is impassable.

@kkaefer ?

[jfirebaugh]

@DennisOSRM Thanks for the info. So (except for 0), the meanings of the modes are completely determined by the profile, e.g. a cycling profile could have 1 = cyling, 2 = walk your bike, 3 = ferry?

[DennisOSRM]

Right, it could be 1 = elephant for that matter.
