How to include polygons as part of a network for Network Analyst (ArcMap)?

Question

I am creating a pedestrian walking network of a downtown area. I am digitizing line segments for paths and sidewalks, but I need to incorporate parking lots into my analysis. So far, I have been creating multiple lines through parking lots to represent possible routes that a pedestrian might take through the lot. This is tedious, and somewhat random. I have my parking lots as a polygon feature class. Is there any way for me to include these polygons in the network by snapping my walking network lines to the parking lot polygons?

Answer 1

in water system management network analysis we had to have a stream centerline for each "pond" polygon, to hold the network information for the pond. HTH

Answer 2

Convert your polygon to line add to your network and use the snap tolerance setting
