Describe the problem

Shape data is presented to end users to help them understand the path taken by a vehicle. The path between two adjacent shape points will appear as a straight line. However, over sufficiently long distances, it’s hard to believe that a vehicle would maintain a perfectly straight trajectory. Some shape files may only set two shape points between two stops, which does not accurately depict the actual (non-straight) path.

Describe the new validation rule

There needs to be threshold value(s) for this proposed rule. E.g.

If [the distance between 2 adjacent shape points > x kilometers]
Trigger the warning (or error)

It would be great to have analytical insights (distance distribution), and check if those extreme values are accurate, before determining threshold value.

Sample GTFS datasets

No response

Severity

Probably warning, but can consider another error with large threshold value, based on analytics.
