This report summarizes the findings of a three-year research project on comprehension of traffic control devices among drivers in Texas border areas. The research evaluated 116 different traffic control devices, which included 33 standard devices and numerous alternative designs for those standard devices. Evaluations consisted of driver surveys in which drivers were presented an image of a device and asked what it meant. Responses were recorded and later classified into categories that reflect understanding of the device. No changes are recommended as supplements for six standard signs. Additional emphasis is recommended for three device categories. Three standard devices are recommended for modifications in design or use. Four devices are identified for future research efforts.
