I'd like to be able to select and count the number of cul-de-sacs, lollipops, dead ends, or other types of street structure in a hillside community.


I'm going to make a few assumptions about your data:

  1. Your roads are in one polyline feature class
  2. Your roads are topologically correct (lines touch at intersections)

If so, you can create a topology and add a rule for "dangles". This will analyse your data for roads that do not touch other roads (i.e. cul-de-sacs, etc).

Here are some links on topologies:

You can then validate the topology and it will highlight dangles. You should be able to count these easily and limit them to your area of interest.


Thanks @Michael Miles-Stimson for the link to the tool to export topology errors.

  • There is a tool Export Topology Errors resources.arcgis.com/en/help/main/10.1/index.html#//… that will export the dangles/self intersections to a point feature class making for easier counting and/or Select by Location. The output includes a description of the 'rule that is broken' to help separate dangles and self intersections. – Michael Stimson Mar 31 '15 at 23:40
  • +1, but note this solution requires a Standard or Advanced license, and is not available at Basic. – Chris W Apr 1 '15 at 1:12
  • Good point @ChrisW. That should be amongst my list of assumptions. There's much missing from the OP's question. – Fezter Apr 1 '15 at 1:14
