| 摘要： | A Fuel Economy Driver Interface Concept (FEDIC) is a device that drivers can utilize to change driving behaviors that affect fuel economy. Three tasks were completed to evaluate and identify FEDIC components that result in behavior changes. The first task consisted of a hierarchical matrix evaluation that resulted in a list of FEDIC components that met user needs. The second task, a usability study, was conducted to evaluate user comprehension and effectiveness of the components. Results indicated that users benefited most from information about fuel economy or behavior when the information was presented in a horizontal bar format. Based on these findings, two FEDIC components were generated for a driving simulation evaluation; one displayed fuel economy information (FEDIC-FE) and the other displayed acceleration information (FEDIC-B). The driving simulator evaluation examined the utility of these FEDIC designs as they were used in typical driving situations where drivers could improve fuel economy. Participants completed a baseline drive and then an experimental drive in which participants were asked to drive as fuel efficiently as possible. During the experimental drive, one third of the participants drove with FEDIC-B, another third drove with FEDIC-FE, and the remainder did not drive with a FEDIC display. Results indicated that drivers were able to improve their fuel economy in all three conditions. Fuel economy for participants who drove with FEDIC-FE was greater compared to those who drove with FEDIC-B or without a FEDIC. The fuel economy for participants who drove with FEDIC-B was not significantly different compared to those who drove without a FEDIC. Collectively, results of Task 3 suggest that the FEDIC displays evaluated may have an influence on driver behaviors that impact fuel economy. A long-term on-road study is required to verify that the FEDICs have real-world value. / Supplementary Notes: Prepared in cooperation with Westat, Inc., Rockville, MD.
