Abstract

Constructed roadways and other infrastructure to support transportation have been around since ancient times. Survey and focus group results in several countries have indicated that older drivers report that they have some difficulties with roadway design features, including making left turns at unprotected intersections, locating and reading signage and pavement markings, and knowing the proper lane to be in for left turns and roundabouts. The fact that roadways were not designed to accommodate the declining abilities of older drivers has long been recognized and several jurisdictions have proposed that improved roadway designs could enhance older driver safety. This chapter reviews research and practice in roadway design infrastructure in relation to older drivers. Covered here are traffic control devices, intersections, work zones, and crashes that are caused by a driver travelling the wrong way on a roadway, a type of crash in which older drivers are overrepresented.
