Abstract
Motor vehicles are the primary mode of transportation worldwide, but drivers must simultaneously utilize various skills and perform multiple tasks at the same time to safely operate the vehicle. As people age, however, physical changes can affect daily life, possibly contributing to declining driving skills. These changes affect vision, hearing, reaction time, and cognitive and motor ability, thus complicating driving. This paper discusses the importance of driving for people of age 65 and older, age-related physical changes, and methods of improving overhead guide sign visibility on roadways. Suggestions to improve navigation and safety on roadways, especially for older people, are presented, including the use of autonomous vehicles fleet.

Summary
Motor vehicles are essential modes of transportation worldwide for drivers of all ages. In the U.S, green signs located along roads are called guide signs These signs are essential for boosting driver’s guidance and safety by providing guidance and information regarding destinations An important focus of the Federal Highway Administration (FHWA) in the U.S is to increase road safety. Despite the fact that 25% of all vehicle travel occurs during night, about 50% of traffic fatalities occur during night (Federal Highway Administration [FHWA], 2008), (Obeidat & Rys, 2017). Departments of Transportation (DOTs) in the U.S are considering two options: adding light sources to the currently installed overhead guide signs on roadways or replacing old signs by new retroreflective sheeting material to increase sign visibility to drivers, especially old age drivers, at night to decrease the potential crashes possibility, which resulted from driver confusion and improper maneuvers. Suggestions to improve navigation and safety on roadways, especially for older drivers, are presented for DOTs and transportation agencies, including the use of autonomous vehicle fleets
