This document describes the results of survey research undertaken by the Automobile Club of Southern California. Questionnaires (10,000) were mailed to insurance customers who own vehicles that may have in-vehicle navigation systems as standard or optional original equipment. Half of the questionnaires were mailed to vehicle owners who were younger than 65, and half of the questionnaires were mailed to owners who were 65 or older. The response rate was approximately 22 percent, including 1,494 respondents who had a navigation system. Follow-up telephone interviews were conducted with 83 navigation system owners. Survey items addressed topics such as learning to use the system, behavioral adaptation, system effectiveness, and perceived safety of the system. Several differences in responses between younger and older respondents were noted. Other response differences were related to vehicle manufacturer and experience with the vehicle (miles driven). |
