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)))"… Show more
Look for accident data... I don't think a true curve is what you want; it's more or less a drawing trick. Not sure your math will find them either: if I understand them they are just looking at the beginning and end. The sinuosity of any line is defined along the way, not just end points, right?
