Statistics indicate that elderly drivers (drivers 65 years and older) are involved in an increasingly high percentage of accidents at intersections. To develop countermeasures to this problem, trafficand geometric characteristics associated with elderly driver accident involvement are identified. The results indicate that the risk ofan elderly driver's being in an accident--expressed in terms of an involvement ratio--is higher at intersections outside cities than atthose inside cities. It was also found that providing longer amber signal times and protected left-turn phases will help the older driver.
