Everyone is welcome to attend.

Traffic control is an essential part of a safe, efficient transportation system. One of three main traffic control devices is signage. This session will cover the three sign classification types (regulatory, warning and guide), sign shapes and colors, proper placement along the roadway network, and maintenance for visibility. A small fraction of this talk applies to Ohio, but the rest applies nationally. There will be examples of both good and bad signage. Poor signage is confusing to humans and will become hazards for self-driving cars.
