Older and younger adults made left turns across traffic in a driving simulator. Time to decide to turn, time to negotiate the turn, the size of the accepted gap, gap clearance, and time to collision with an oncoming vehicle were measured. Significant effects of age were found in decision time, turn time and gap size. A significant interaction between age group and the speed of oncoming traffic was obtained for decision time. Implications for older adult's safety and future directions are discussed.</p>}, month = {6}, pages = {97-103}, publisher={University of Iowa}, journal = {Driving Assessment Conference} }
