In light of Delaware’s growing population age 60 and older (60+), it is important to plan for the

state’s projected increase in older drivers. Information from the United States Census Bureau

(2005) indicates that Delaware is projected to have the ninth largest percentage of elderly

residents to general population by 2030. Additionally, research from the University of

Delaware’s Center for Applied Demography and Survey Research (2006) illustrates that Sussex

County is projected to experience the most significant percentage growth between 2000 and

2030.

Delaware reflects national trends in terms of its percentage of licensed drivers over the age of 65.

According to the Delaware Department of Transportation (2004), in 2003, 15.3 percent of

licensed drivers were over the age of 65. Many younger seniors (50-65) prefer to drive, and with

few transportation alternatives in the state, dependency of private vehicles is likely to continue.

However, factors that pose risks to older drivers include impaired vision, diminished cognition,

and decreased motor-function (Carr, Duchek, Meuser, and Morris, 2006).

Current road designs should be reviewed to determine whether modifications are necessary to

better accommodate Delaware’s older drivers. Possible modifications include making

intersections more driver- and pedestrian-friendly and improving traffic signs and signal design.

Additionally, comprehensive assessment, education, and outreach programs can assist

individuals, families, and physicians facilitate discussions about driving and promote mobility

and independence among older Delawareans. Like other states that are addressing this issue,

Delaware should apply resources for such modifications and initiatives to areas that pose the

greatest safety concerns. Chosen areas should be based on the state’s current and projected

demographic trends as well as crash data. Better coordination and collaboration among state

advocacy groups and agencies will also foster overall improved awareness and education for

individuals and their families who are concerned about the potential risks associated with older

drivers.

This paper begins with an overview of the issues and implications related to driving and longterm

mobility. Sections 1-5 are part of a literature review that includes research studies, case

studies, and best practices on subtopics related to older drivers. These subtopics include

intersection design, traffic signs and signal design, and education and awareness programs.

Finally, Section 6 provides a list of priorities and recommendations for considered by units of the

Delaware Department of Transportation (DelDOT) and other state agencies based on the

Delaware’s demographics trends and current transportation-planning practices and resources.
