I am trying to run a closest facility analysis but routes are only being calculated for 4 of my 54 incidences. For the remaining 50 incidences I get... �??Warning: No "Facilities" found for "XXX" in "Incidents"�?�. It looks like the routes are not making turns at any junctions.
I have found that a connectivity issue is usually the case, but I have created a network dataset from the New Jersey Roadway network http://www.state.nj.us/transportation/gis/data.shtm and it looks like the network is connected and it comes up with junctions at every interest when the network dataset is created. I have also snapped the facilities and incidences to the network.
The only attribute I have in my network dataset is �??length�?� as a cost because I am only concerned with the distance traveled when determining a route.
I have had the connectivity policy set to any vertex and end point, and neither has worked.
Any help would be appreciated.
Thanks,
Brent

I just downloaded the shapefile, imported it into my own pgdb and then clipped out a dense area on the east side of the state. (Not familiar with NJ, so I don't know the town).
Looks like there are some major connectivity issues to me. Or should I say lack there of. See the attached screen shot. For each of the selected streets, I only 'clicked' on one end to select it. Shouldn't there should be intersections along the way?
Try to create a service area by just interactively dropping a 'facility' around the state and see what you come up with. My guess is you'll see a lot of what I show here.

Here is what I came up with for the service area test...

I see what you are talking about, I planarized the network to divide the network at each intersection and still not luck.
Unfortunately my facilities and incidents are spread throughout the southern 2/3rds of the state.

1) In the layer properties. What is set in Layer Properties > Analysis tab > Default Cutoff Value?
2) In the facilities features attribute table. Open the attribute table for Facilities...is there anything besides null values in the Cutoff_Length field?

The default cutoff value (under: Layer Properties > Analysis tab > Default Cutoff Value) was null, but I set it to a 1000 miles to see if that did anything.
and...
In the attribute table for Facilities there are only null values in the Cutoff_Length field.
I am at a loss.

This is what I tried:
Next, I did the following:
Can you send the data if you continue to get the same errors?
