A few weeks ago I posted about using street light buffers. I feel that it would be more beneficial to use "classes" of lighting; that is, Class 1 is the best lit whereas Class 5 is the worst lit, with Classes 2, 3, and 4 in between. I built a model which I believe will be able to make the necessary shapefiles. Unfortunately, the model always fails at the Select tool. What is the best way to get this to work?

I have a diagram of what I mean with the "classes", plus an image of the model, below.

Guy,

One thing you might try rather than using the union function for all the buffers is to try and use the "Identity" tool to overlay them.  This will preserve the boundaries for each buffer.  You can then assign classes to each buffer distance and use that for creating your {where clause} in the Select tool.  If I understood your question correctly, this should work.
