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

[Eric Palakovich Carr]

Thanks for the tip, Alex.  I've contacted my local city government and it
appears I'll be able to get data on traffic signals, stop signs, and turn
restriction signs.  I don't really have any reason to horde the data all to
myself, so I'll probably contribute it to OpenStreetMaps (assuming I get the
data in the end).

I just started nosing around in OpenStreetMaps yesterday, so I'm pretty
green on how to go about adding this data when I get it.  Do I add a traffic
light tag to an existing road?  Would I create a point for each light / sign
and associate with the road?  Can a point be associated with more than one
road?
