Summary
This report, part of the National Energy Efficient Driving System (NEEDS) project, investigates methods for integrating fuel-efficient driving instruction into high school driver education programs. Motivated by the potential for 10–15% fuel savings through improved driving behaviors and the widespread reach of driver education courses, the study aimed to identify young driver deficiencies and evaluate the effectiveness of various instructional approaches. The research addressed four key questions: the nature of driver deficiencies in knowledge, attitude, and skill; the necessity of behind-the-wheel instruction; the role of in-car feedback aids; and the optimal integration of these techniques into existing curricula. The study comprised four distinct components. First, a deficiency analysis assessed 4,279 high school students and experienced drivers using knowledge tests, attitude surveys, and performance measurements. Skills were evaluated using the Driver Performance Measurement and Analysis System (DPMAS) on a closed course and a five-mile on-street route. Second and third, two experiments tested the efficacy of classroom-only versus classroom-plus-in-car instruction. These studies compared pre- and post-training knowledge, attitude, and performance scores across experimental and control groups. Fourth, a vehicle study examined the relationship between acceleration rates and fuel economy using six instrumented automobiles with automatic transmissions, testing low (.1 g), moderate (.2 g), and brisk (.3 g) acceleration levels. The findings revealed significant gaps in driver knowledge regarding fuel efficiency, with average correct response rates ranging from 33% to 45%, regardless of driving experience. While attitudes toward operation and maintenance were favorable, attitudes toward vehicle selection were less aligned with efficiency. Performance data indicated that novice drivers exhibited high variability in fuel consumption, whereas experienced drivers were more uniform. Crucially, neither classroom-only nor combined classroom/in-car instruction significantly improved actual driving performance compared to control groups, although classroom instruction alone improved knowledge scores. In-car training provided no additional benefit for knowledge or attitude improvement. The vehicle study determined that moderate acceleration was generally optimal for fuel economy, with some variation based on vehicle weight. The study concludes that while young drivers possess favorable attitudes toward fuel conservation, they lack the necessary knowledge and skills to drive efficiently. Current driver education programs fail to impart this knowledge, and adding in-car training does not enhance performance outcomes. The research suggests that fuel-efficient driving programs are viable for novice drivers due to the accessibility of high school curricula, but effective implementation requires addressing the identified knowledge and skill deficits without relying on costly in-car aids that do not yield superior results.
Key finding
Classroom instruction improved fuel-efficiency knowledge but did not enhance driving performance, and adding in-car training yielded no additional benefits over classroom instruction alone.
