Does a tool exist to place a point at a road intersection?

If you like scripts you might try this one. Without scripts, here's how I'd do it. It's not totally straightforward but it should get you there.

Are your roads segmented at intersections? If not, this thread has instructions. There's a Feature to Point tool under Data Management Tools which can place points at line ends. For a 4-way intersection that would make four points, and you'd get points at dead ends like cul-de-sacs. To clean it up I'd do a spatial join with a sum option (the join requires two layers so I'd make two copies of the same points layer). That will create an attribute field showing how many points are at a given location. Delete any that say 1, those are your dead ends. Then do a Dissolve which will merge all those other groups of 2, 3, and 4 points into a single point at each location.

We have added a tool to the address toolset that create a point at road interections with intersected road names. I can provide a beta version of this add in if you want to try it out. Please send an email to me at mmiller@esri.com if you want a copy.
