Please note the following: To set the all-way stop tags on an intersection, select the intersection point, select "Stop Sign" as the feature type and then select "All Ways" under the "Stop type" box. To set the traffic signals tags on an intersection, select the intersection point and select "Traffic Signal" as the feature type. Always check the satellite imagery to confirm what the MPO data indicates. If you're unsure about something please ask around. There's bound to be someone in the room familiar with existing conditions at the location you're looking at. If you come across a situation that doesn't exactly fit the basic tagging that has been outlined, please find a knowledgeable OSM mapper to provide guidance.
