List of transit modes or travel options supported by OTP?

[brylie]

We are developing an open-source transportation CO2 estimation library, with planned support for multi-leg and multi-itinerary estimation. Our estimator is based on a model published by the European Environment Agency, with per-passenger-kilometer CO2 coefficients for a few transport modes. We would like to align with the OTP project by ensuring we have a map of all OTP modes to produce CO2 a CO2 estimation from our library.

Is there an official list of transport modes supported by the OTP, such as in the TravelOption class?

The TravelOptions are listed in the RouterInfo class, which can be fetched from the api using the path /otp/routers/<routerId>. Example

All modes are listed in the TraverseMode enum

Thanks for your quick response @hannesj

FYI: In OTP2 we will probably start on supporting the extension modes (GTFS) and NeTEx submodes in the near feature - how we will support this is an open question, and there is no issue for it yet, but in my head sub-modes should be configurable - not statically hardcoded into OTP. If so we can have an official default config with GTFS and NeTEX modes and when needed each deplyment can extend it with any needed mode.
