TRAVELERS PREFERENCES FOR IN-VEHICLE INFORMATION-SYSTEMS - AN EXPLORATORY ANALYSIS

A sample of travelers' preferences toward in-vehicle traffic informati on systems was undertaken and appropriate statistical models were esti mated. Specifically, ordered legit and regression analyses were conduc ted to quantify travelers' ratings of the importance of in-vehicle sys tem attributes, and the distance ahead that they prefer to be notified of various types of information provided by in-vehicle systems. Model estimation results show that travelers' socio-economics, habitual tra vel patterns, commute congestion levels and attitudes toward in-vehicl e technologies are significant determinants of travelers' importance r atings and the preferred distance ahead of in-vehicle system informati on. These model results provide important information for both marketi ng and design of in-vehicle information systems.
