Emergent Paths through a city

Hello,

I am trying to add a component to a definition that would create emergent paths through empty lots & parking lots across a few blocks in a city.  

Right now I am using the delaunay edges function to create paths between the closest points, but the paths are slicing directly through buildings.  


This image shows the empty lots (red) and the delaunay edges connecting to the centers of the lots.  Ideally the definition would replicate a kind of secondary emergent system of trails through this area.


Thanks for taking a look!

one way is to set way points on the street so the lines know where the streets are and then perhaps try the traveling salesman algorithm or 2d proximity(already in GH).

Thanks for the tip-- had a fun-filled afternoon of learning about the traveling salesman problem.

if you want you can use galapagos to emulate the traveling salesman because it can solve for the shortest path through the pointset.
