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).</span></div>

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?</div>
