Wayfinding errors while driving

There is evidence to suggest that wayfinding problems represent a threat to driver safety and mobility, lead to wasted time and fuel, contribute to traffic congestion and cause drivers stress and embarrassment. Certain groups of drivers, such as the elderly, are more likely to experience difficulties navigating. A study was conducted to investigate the problems that drivers experience while trying to find their way. A postal questionnaire survey of U.K. drivers, aged 21 to 85, was conducted (n=1184). A model was developed to explain the navigation process while driving and identify the types of errors that occur. Wayfinding errors were found to be mistakes caused by a lack of appropriate information and constraints on driver decision-making. Elderly and female drivers tended to perceive wayfinding as being more difficult than nonelderly and male drivers. However, elderly drivers did not experience more frequent wayfinding problems. Solutions to wayfinding problems in general should be directed at improving road signs to support more accurate situation assessment and decision-making. (C) 1998 Academic Press.
