Hello,
We would like to identify dangerous tight curves in our road database.
To start I calculated a field called 'Sinuosity' with the following expression:
"!Shape.Length! / (math.sqrt(math.pow((float( !Shape.FirstPoint.X!) - float( !Shape.LastPoint.X!)), 2) + math.pow((float( !Shape.FirstPoint.Y!) - float( !Shape.LastPoint.Y!)), 2)))"
I then downloaded a geoprocessing script called 'Identify True Curves' which creates two output feature classes:
OutputCurvePoints and OutputWithCurves
It also creates two temp files: tmpSourceVertices and tmpDensifiedVertices
I have successfully run the model but it is really not what I am looking to accomplish.
Does anyone have a way to find these dangerous hairpin turns?
I am using ArcInfo 10.1.
Thank you,
Dorothea
