[Geodata] Stop signs, traffic lights, and other street intersection data

[Eric Palakovich Carr]

Hi,

I need data on street intersections in the USA.  In particular, what street
lights, stop signs, or other entities exist at the intersection that affect
how traffic moves through it.  The data should also indicate what streets
that hit the intersection are affected by the entity.

Does a data set like this exist?
