Implement trip distance vs. shape verification (GTFS rule)

[maximearmstrong]

Is your feature request related to a problem? Please describe. The distance traveled by a trip should be less or equal to the max length of its shape. This is a GTFS rule implemented in Google Python validator and featured in Google Type Error as TYPE_TRIP_WITH_OUT_OF_ORDER_SHAPE_DIST_TRAVELED.

Describe the solution you'd like Actual Google GTFS validator behaviour : verifies if distance travelled is smaller than shape length

Describe alternatives you've considered

@maximearmstrong Could you point us to where this rule is implemented in the Python validator? I don't see it from a quick search.

Labeling as blocked because there is no mention of this in the spec or best practices

[isabelle-dr]

We have a PR open to add this to the spec: https://github.com/google/transit/pull/380. If this doesn't pass, we can discuss adding this as INFO.

Unblocked now that https://github.com/google/transit/pull/380 has passed 🎉

@cka-y's work on the analytics for the spec issue will be relevant to the logic here.
