I'm in the process of creating some routes for which I need left and right sections. I have an original streets feature class, which I used "copy parallels" on, and came up with something like the picture below.

I'm wondering if there is any tool that would clean up these roads, erase some dangles and intersecting lines. I've tried using the "trim" tool, but cannot come up with a standard length to trim.

Any ideas?


Using ArcGIS 10.2.1 Advanced


I assume that you did a copy parallel equally on the left and the right of your original roads. So, in order to clean up a bit, you could

  1. create a buffer polygon of the same size and dissolve all the boundaries. Because you have advanced licence, you can set up flat ends, it will be nicer in your case)
  2. Use "feature to line" with your lines in order to split them where they intersect.
  3. select by location the lines that share a line segment with your buffer polygons.
  • Should I make the buffer a tad smaller? So not all lines will share a segment with the buffer – Maksim Jan 28 '14 at 14:39

    no, it has to be exactly the same. sharing a line segment is more constraining than intersect : it means that the intersection with boundary must be a line (with intersect, the instersection can be point). – radouxju Jan 28 '14 at 14:42
