摘要：The authors propose the use of micro-electric vehicles called “silver vehicles” (SV) as mobility devices for older drivers who have difficulty driving automobiles. Previous reports have described research on characteristics of the elderly, proposed the {SV} concept and evaluated it in townmobility field tests. This report addresses feasibility of the {SV} concept and issues of town planning through a follow-up study of characteristics of the elderly three years later, long-term in-use testing of SV-comparable production vehicles, and investigations of elderly driver characteristics and trailing behavior in mixed traffic situations.
