Network Path Planner Choices

[MikeHammett]

I have built a Network Dataset based on the Illinois DOT all roads shapefile.
I have created a point file of central offices and a point file of potential subscriber locations.

One of the COs is ignored entirely, and another is only used for three subscriber locations. I assure you that three is severely undercounted.

I output some diagnostic information, but I get a bunch of information that I don't know how to load. The files I've opened are binary, not a plain text files I'm used to.

ArcGIS Pro 3.3.1

I think I'm using Network Path Planner 2.2.

Hi Mike,

Send me an email at gjoseph@esri.com and I can help troubleshoot what might be going on.

Thanks,

Gelisa

I am seeing a similar problem. 

I created a Network Dataset from a portion of the Streetmap Premium data, network locations based on existing network enclosures and target addresses to service. 

The Pathplanner fails to generate routes for roughly 15% of the targets.  The Network Dataset appears to show roads (paths) from the unsupported targets to near enclosures. 

Similarly to Mike's results, other targets have paths which route to distant network locations.

Hello Eric,

Did you create your own network dataset? If so something we've seen when a many target sites are not routed to is that the network dataset needs to change the connectivity model (midspan connectivity) or split lines. 

I've seen results greatly improved by splitting the lines. Of course depending on the dataset size this can take a bit of work.

To split the lines you can do the following:

1. Use the Pairwise Intersect tool 
   1. Input Feature - Streets
   2. Output type - Point
2. Use the Split Line at Point tool
   1. Input - Streets
   2. Point Feature - Results from running the Pairwise Intersect tool
   3. Set a default radius (this improves the time it takes to run)
3. Rebuild you network dataset with the newly split lines.
