ERROR 130121: Input polyline features have existing calibration points

Regulus — Wed, 22 Apr 2026 21:41:59 GMT

Hi,

I am working through ArcGIS Roads and Highways: Introduction to Modeling and Data Management. Section 3: Exercise - Load LRS network data. I am trying to append source routes data to the CityNetwork feature class. The Geoprocessing tool, Generate Calibration Points, is giving me this error message.

These are the details in the text file it creates:

"Number of route and existing calibration point combinations which had duplicate route IDs and time span overlaps: 913
Object IDs of routes and existing calibration points which had duplicate route IDs and time span overlaps:
(Format is 'ObjectID_in_input_polyline' + 'ObjectID_in_calibration_point')
488+930,318+566,1115+1802,1117" <many more of these numbers and +'s>

How can I get past this? Thank you

I just re-did that section and everything went perfectly this time. I am not sure what went differently. But I noticed in Step 3L of Section 4, where it says "Click any route on the map to identify it," the pop-up showed the information. But Step 3M says, "Notice that in the pop-up, the measure information is not available." Then the next step is where I got the error message I referenced in the original post. Still if anyone has insight, I would be interested.
