This research overview deals with simulator studies involving older participants, of about 65 years of age or older. The overview has been structured in accordance with the aims the studies referred to regarding simulator driving. In the driving simulator evaluations have been made of the benefit of various types of support systems for the driver, further driving behaviour has been investigated (in general and in particular situations when secondary tasks are carried out, etc.), as well as how the simulator functions as an instrument for assessing driving ability. As a rule, groups consisting of younger persons, and sometimes also older middle-aged persons, also participated in the studies, but often the interest has only been directed towards the performance of older drivers. Types of simulator vary: everything from advanced dynamic ones with half car bodies and sophisticated display systems similar to those that VTI has, to more basic, stationary ones, with one or more monitors for display, instrumentation and car seat. Few studies describe how simulators have been used for training or education of older people. Also, only a limited number of validation studies involving older people have been found. The problem of simulator sickness is discussed, too.
