Error when calculating service areas

Hi,

I am trying to calculate relatively small service areas (1000 feet) around the centroids of blocks in a city. I have about 10k centroids for which I'd like service areas.

I am only able to generate service areas for some of the points and get the following error message for the others:

"The delay impedance of "Location X" in "Facilities" exceeds the cutoff impedance."

Any idea why I'm getting this?

Thanks in advance!

Looks like you must have loaded some "delay" value when you did the load locations. Most likely you had a field that mapped automatically to the attr_"length" field. Open up the attribute table for the facilities and see what values are listed for this field. If it is not 0.0 then use a field calculator and calc them to 0.0

For more information on delay, see the topic for Attr_[Impedance] at:
