- Reduced fuel consumption by lower speeds on roads would reduce emissions. Do drivers, who choose vehicle speed, realize the gain in fuel of a reduced speed? Judgments of fuel consumption at increasing and decreasing speeds were made by professional truck drivers and student groups when they were not driving. For decreases in speed, truck drivers underestimated fuel saved significantly. Engineering and psychology university students’ judgments also tended to underestimate fuel saved but not statistically different from the correct values. For increases in speed, the truck drivers judged the fuel they would waste close to correctly. The psychology student group overestimated the fuel wasted following an increase in driving speed as did the engineering students but only for speed increases greater than 30 km/h. The results indicate that eco driving systems need to support drivers’ judgments of fuel saved or lost if they change their driving speed.

Book chapter (other academic/artistic)abstract
- Two driving simulator experiments were conducted to assess different alternatives of lane departure warning and assistance systems. In the first experiment, two types of Lane Departure Warning system (LDW) were compared with one Lane Keeping Assist system (LKA). In the second experiment, the benefit of an LKA was assessed as compared with the condition of no LKA. In addition, similar steering wheel support as for lane departures was implemented as a Lane Change Decision Aid system (LCDA) in the second experiment, giving feedback in so called blind spot situations. The purpose was to investigate the possibility to have the same type of support for different lateral threats in order to harmonize and simplify the overall support given to the driver. Results indicate some deviating driving behaviour for novice drivers and generally a positive objective and subjective results supporting LKA consisting of a combination of guiding steering force and vibrations of the steering wheel.
