Abstract Given the recent introduction of many innovative designs, still relatively limited material exists that explains the concepts, tradeoffs, and benefits underlying such innovative intersection designs in a form accessible to the general public. This project was designed to both test the effectiveness of existing GDOT public information materials and to develop a library of additional presentation materials to support and supplement these existing communications materials.
