Find area by Distance

Hello,

I thought that I would find the answer to this question easily, but it seems as though I don't actually know if this is possible, so here goes: I have a networked road dataset and a set of origin points representing fire stations. Each road line segment has a length of course, and I want to produce a map of all the road segments within 1.5 miles of the stations by travel distance. So not just a buffer but from a given station, using the networked roads, select those that as you travel them equal 1.5 miles or less.

Does that make sense? Is there a tool in Network Analyst to do this kind of analysis?

Yes, you can do this using a Service Area analysis. In particular, if you want to show the road segments reachable instead of a polygon buffer, set the output type to show Lines.

Thanks, exactly what I wanted! I'd done time-based analysis before, but just missed the distance available.
