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:
- Your roads are in one polyline feature class
- 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.
