Traffic Light and Stop Sign Best Practices - TelenavMapping/Telenav_mapping_team_practices_and_workflow GitHub Wiki
Traffic lights(or traffic signals) are lights used to control the movement of traffic. They are placed on roads at intersections and crossings. The different colors of lights tell drivers what to do.
Stop sign is a traffic sign to notify drivers that they must come to a complete stop and make sure no other cars are coming before proceeding.
highway=traffic_signals
traffic_signals:direction=forward/backward
The key forward hereby refers to lanes which direction is equal to the direction of the OSM way, and backward to the opposite direction.
If there is just a pedestrian crossing, the properly tags are:
highway=crossing
crossing=traffic_signals
Forward means the direction in which the way is drawn in OpenStreetMap, while backward means the opposite direction.
highway=stop
direction=forward/backward
The key forward hereby refers to lanes which direction is equal to the direction of the OSM way, and backward to the opposite direction.
