/**
* Model bike access for GTFS trips.
*
* The GTFS bike extensions is originally discussed at: https://groups.google.com/d/msg/gtfs-changes/QqaGOuNmG7o/xyqORy-T4y0J
*
* It proposes "route_bikes_allowed" in routes.txt and "trip_bikes_allowed" in trips.txt with the
* following semantics:
*
* 2: bikes allowed
1: no bikes allowed
0: no information (same as field omitted)
*
* The values in trips.txt override the values in routes.txt.
*
* An alternative proposal is discussed in: https://groups.google.com/d/msg/gtfs-changes/rEiSeKNc4cs/gTTnQ_yXtPgJ
*
* Here, the field "bikes_allowed" is used in both routes.txt and trip.txt with the following
* semantics:
*
* 2: no bikes allowed
1: bikes allowed
0: no information (same as field omitted)
*
* Here, the 0,1,2 semantics have been changed to match the convention used in the
* "wheelchair_accessible" field in trips.txt.
*
* A number of feeds are still using the original proposal and a number of feeds have been updated
* to use the new proposal. For now, we support both, using "bikes_allowed" if specified and then
* "trip_bikes_allowed".
