003121: For some shapes, the measured distance of stops along the shape line does not match the correct sequence of the stops. This likely indicates a problem with the geometry of the shapes. The shape_dist_traveled field will be added to your output stop_times.txt file and populated, but the values may be incorrect. Affected shape_ids: <value>

Description

The linear referenced values of stops along some shapes do not correspond to the correct sequence of stops. See the Features To GTFS Shapes tool documentation for details.

Solution

Examine the problematic shapes in your input data and use the editing tools to update the shapes. See the usage notes for the Generate Shapes Features From GTFS tool for editing tips.
