This article presents results from a randomized controlled eco-driving experiment with differential treatment between two groups of truck drivers in Norway. Using data from in-vehicle devices, we investigate whether eco-driving interventions (a course, active monthly follow-ups, and non-monetary incentives) reduce fuel consumption by inducing more efficient driving behavior for drivers in a treatment group, compared to a control group. Hereby, we consider persistence of effects over time and the relative importance of eco-driving factors, while controlling for fixed vehicles, routes, drivers, and weather.

We find significant fuel consumption reductions, persisting over a longer period of time than in most previous studies (where effects fade or disappear), that weather conditions are important, and evidence of an ‘eco-driving learning curve’. This might result from monthly follow-ups and driver rewards. Further, we find spill-over effects through significant fuel savings for drivers in the control group (undergoing no interventions). These are likely the result of them becoming aware that ‘something eco-driving related’ is going on.

Our analysis suggests that improvements on engine and gear management contribute most to fuel savings. We estimate the potential for fuel savings to lie between 5.2 and 7.5% (lower bound, control group) and 9% (upper bound, treatment group). This implies a potential for significant cost savings and emission reductions, which might to some extent be scalable and transferable to other settings. As such, eco-driving may play one part in reducing emissions from road freight, for which much-needed emission reductions are challenging to achieve, especially in the shorter run.

本文介绍了在挪威两组卡车司机之间进行差别待遇的随机对照生态驾驶实验结果。使用车载设备中的数据，我们调查了与驾驶室相比，生态驾驶干预（课程，积极的每月跟进检查和非金钱激励措施）是否能够通过诱导治疗组驾驶员更有效的驾驶行为来减少燃油消耗。控制组。因此，我们在控制固定车辆，路线，驾驶员和天气的同时，考虑了随时间推移的影响的持久性以及生态驾驶因素的相对重要性。

我们发现燃料消耗量显着减少，并且比大多数以前的研究（影响消失或消失）持续了更长的时间，天气条件很重要，并且有“生态驾驶学习曲线”的证据。这可能是由于每月的跟进和驾驶员奖励所致。此外，我们发现节油效果是通过为对照组的驾驶员节省大量燃油（不采取干预措施）来实现的。这些可能是他们意识到“与生态驾驶相关的事情”正在发生的结果。

我们的分析表明，发动机和齿轮管理方面的改进最大程度地节省了燃油。我们估计节省燃料的潜力在5.2至7.5％（下限，对照组）和9％（上限，治疗组）之间。这意味着可能会节省大量成本并减少排放，在某种程度上可以扩展并转移到其他环境。因此，生态驾驶可能在减少公路货运的排放中起着一定的作用，这对于实现急需的减排是一项挑战，尤其是在短期内。
