  • Road Design and Traffic Operation Guidelines to aid the Older Motorists

    Studies show that the number and percentage of older people in general, and older drivers in particular, are growing rapidly. By the year 2025 people aged 60 and over are expected to account for about 24 percent of the European population, 22 percent of the Northern American population, and almost 14 percent of the world population.
