Elderly and teenagers are the most common age groups involved in car crashes according to recent research.However,driver ethical and pragmatic concerns bring many research limitations to on-road testing.This makes getting information from drivers,especially elderly in hazardous situations,difficult.The objective of this study is to gather a greater understanding about prevalent driving weakness associated with elderly and teenagers,and build up specific experimental environment to address drivers features on driving simulator; and thus,obtain behavioral signatures of aged and teen drivers during hazard events through experimentation.In this project,the driving behavior of both young,experienced drivers(N=15,Mean=19.5,SD=0.83)and elder drivers(N=5,Mean=68.0,SD=6.40)were compared and analyzed as a pilot experiment.The virtual environment test is around 15 minutes long with around 7.5 miles of driving and consists of N=15 hazard events randomly scattered in both urban and rural zones.As a result,compared with young adult drivers,elder drivers showed more crashes,less violations to red light and stop signs,longer completion time,lower average speeds,etc.Besides this,elder drivers suffer more easily from simulation sickness like sweat and nausea,mainly due to the lack of video games experience and age-related decline compared to young drivers,as self-reported.This pilot study can help to identify the genesis and features of car accidents that involve aged groups.
