This literature review focuses on human factors issues affecting older adults’ safe use of cutaway 3 buses (ie, a bus body carried by a van or truck chassis) that are often used as shuttles for 4 assisted living facilities, in demand-response and paratransit services such as dial-a-ride, as well 5 as in mainstream public transportation and shuttle systems. Because of the scarcity of data 6 gathered specifically on American cutaway buses, this review uses international statistics on 7 paratransit, demand-response, special transportation services (STS), and dial-a-ride services as 8 substitutes, since these are the areas of public transportation that most frequently use cutaway 9 buses. In the first section, we follow a user-centered approach by reviewing some the factors 10 related to older adults’ driving cessation and how public transportation systems that use cutaway 11 buses help make this life change easier, followed by the physiological changes that occur with 12 age that decrease older adult passengers’ ability to withstand a motor vehicle crash (MVC), 13 ending with those that limit older adult mobility while boarding or alighting the bus, or 14 navigating the cabin. The second section consists of a review of bus crash statistics to see what 15 types of injuries and outcomes are associated with older passengers in different types of MVCs. 16 Finally, areas of concern and possible solutions to improve older adults’ safety when using 17 cutaway buses are presented. 18
