Signs are important fixtures that help advance roadway safety every day throughout the United States. Today, a variety of symbols, shapes and colors are used to convey messages to users on and around the roadways. Signs types include traffic, roadway, warning, railroad, guide, recreational, temporary, regulatory, pedestrian and bicycle.
There are many benefits to using symbols, which include immediate communication with all roadway users and their ability to break language barriers. Colors can communicate approaching scenarios such as using orange to indicate an upcoming work zone or red for an upcoming stop or yielding point. A number of shapes are also used to indicate oncoming situations or to provide roadway users with information such as octagons for stop and long horizontal, rectangular signs displaying guidance information.
Today, traffic signs are being looped into the world of autonomous driving technology. Research efforts are being made to equip traffic signs with technology, like embedded machine-readable codes, to allow them to communicate with Connected Automated Vehicles (CAVs) and other mapping devices.
