The original Older Driver Highway Design Handbook was published by FHWA in 1998 (FHWA-RD-97-135). The 2nd edition, titled Highway Design Handbook for Older Drivers and Pedestrians (FHWA-RD-01-103) was published in 2001. This 3rd edition, under a new title, incorporates new research findings and treatments to improve the safety of the transportation system for the aging population.
The Handbook is divided into three sections. The first section explains how to use the Handbook to select treatments to address problems for aging drivers and pedestrians. The second section includes treatments for 51 proven and promising traffic control and design elements distributed among five categories: Intersections, Interchanges, Roadway Segments, Construction/Work Zones, and Highway-Rail Grade Crossings. The final section of the Handbook includes the rationale and supporting evidence for the treatments.
