Assigning Name to Each Points
My python code :
import arcpy
arcpy.FeatureToLine_management("Closestroute", "Featureline", "0.0001 Meters", "ATTRIBUTES")
#Generate points along lines for every 1 km
arcpy.GeneratePointsAlongLines_management("Featureline", "splitPoints", "DISTANCE", "1000 Meters", "", "NO_END_POINTS")
#Split line at point for every 1 km roads,search radius = 20 meters
arcpy.SplitLineAtPoint_management("Featureline", "splitPoints", "split1kpoints", "20 Meters")
#I added SS field into splitPoints, then I assigned name for each rows.(s1, s2, s3, ...)
cursor=arcpy.da.UpdateCursor("splitPoints","SS")
i = 0
for row in cursor:
row[0] = 's' + str(i)
i += 1
cursor.updateRow(row)
del row
del cursor
My problem is:
I am trying to assign one name for each points. However, when one route are used by more than one start points like blue arrow in the picture below, I obtained more than one segments name for this route. I am trying to get just one segments name for each points for this route. (showed with blue arrow) for both start points.
How I can deal with this problem ?

With the DA cursor, can you check if the Name is blank, then populate?

It looks like points are stacking up due to duplicate line features or line feature segments. I'd perform a delete identical on your output point feature class, either before or after your cursor.
shpFld = arcpy.Describe ("splitPoints").shapeFieldName
arcpy.DeleteIdentical_management ("splitPoints", shpFld)

Thank you so much ! This helps a lot !! Since I am assigning name in order, although one segment is used by two shortest paths, in attribute table, shows for just one start-end point shortest path. I have posted my guestion. If you can take a look, I will be appreciated for that. @Emil Brundage
