The aim of the study was to measure the effects of the education in environmental friendly driving that is included in the Swedish driver education for license class B on fuel consumption and a selection of driving behaviours that are typical for environmental friendly driving among drivers with license since half a year.
In this evaluation of the environmental components of the Swedish driver education class B, license holders that obtained a license since half a year have been asked how much education in environmental friendly driving they have received. Their answers have been used to define a group of 25 drivers with much such education (group M) and a group of 25 drivers with little or none such education (group L). These drivers have driven an instrumented car along a pre-defined road of 30 km where 12 parts were used to collect data about fuel consumption and a selection of different driving behaviours. As a reference, an expert/educator in environmental friendly driving “E” has also driven the same road as the others with the purpose of indicating what is possible to achieve.
The results, based on a number of hypotheses, showed that:
- group M consumed less fuel than group L in total and on all the 12 sub-roads
- group M was driving with lower speed than group L in total and on all the 12 sub-roads group M generally used the brake less than group L on 4 of the 12 sub-roads
- group M used the brake less than group L when approaching a STOP sign
- group M used the clutch less frequent than group L on 1 of the 12 sub-roads
- group M used the clutch during a slightly shorter time than group L when approaching a STOP sign.
- group M was generally driving more often with zero consumption than group L on 5 of the 12 sub-roads
- group M was driving more often with zero consumption than group L when driving downhill
- group M was generally driving with lower average rpm than group L in total and on all 12 sub-roads.
- group M was driving less with rpm above 3000 than group L when accelerating after a STOP sign
- in none of the measured behaviours, none of group L or M reached the level of E
- all the hypotheses except one (about average speed) were correctly formulated since E performed better than both L and M
- the hypothesis about average speed was probably incorrectly formulated since E was driving faster than M on most of the sub-roads.
