This study investigated the pre-trip and en route decision processes that typify driver decision making about route choices and route diversion. Verbal commentary methods were used to expose on-going perceptual and evaluative activity while participants made normal trips, unaccompanied, in their own vehicles. The trips included morning home-to-work commutes, evening work-to-home commutes, evening or weekend trips to an unfamiliar shopping mall, and weekday, off-peak trips to a downtown business area. Twenty-four paid participants took part, all in the greater Washington, DC, area. Each participant received extensive training, via a training video and a supervised training session, before being provided with an in-vehicle video recording system and recording specified trips. The information collected included pre-trip information sources and decisions, and continuous en route commentary on information sources, decisions questions, strategies, major concerns, information needs, and errors. At the conclusion of each trip, additional information was collected on the drivers perception of various aspects of the trip and the related information sources and needs. |
