Using on-board logging devices to study the long-term impact of an eco-driving course

Transportation Research Part D Transport and Environment (Impact Factor: 1.29). 10/2009; 14(7):514-520. DOI: 10.1016/j.trd.2009.05.009

ABSTRACT In this paper the long-term impact of an eco-driving training course is evaluated by monitoring driving behavior and fuel consumption for several months before and after the course. Cars were equipped with an on-board logging device that records the position and speed of the vehicle using GPS tracking as well as real time as electronic engine data extracted from the controller area network. The data includes mileage, number of revolutions per minute, position of the accelerator pedal, and instantaneous fuel consumption. It was gathered over a period of 10months for 10 drivers during real-life conditions thus enabling an individual drive style analysis. The average fuel consumption four months after the course fell by 5.8%. Most drivers showed an immediate improvement in fuel consumption that was stable over time, but some tended to fall back into their original driving habits.

    • "efs , as argued by Carrico et al . ( 2009 ) , with respect to the economic benefits and environmental impacts of cold engine idling and restarting the engine . Therefore there is scope for policies aimed at providing drivers with appropriate information and incorporating the principles of efficient driving into driver training ( Barkenbus , 2010 ; Beusen et al . , 2009 ; Onoda , 2009 ) . At the same time , price incentives make this information as well as the implied behavioral changes economically meaningful and should therefore stimulate demand for them ."

    ABSTRACT: The volume of pollution produced by an automobile is determined by driver's behavior along three margins: (i) vehicle selection, (ii) kilometers driven, and (iii) on-road fuel economy. The first two margins have been studied extensively, however the third has received scant attention. How significant is this 'intensive margin'? What would be the optimal policies when it is taken into account? The paper develops and analyzes a simple model of the technical and behavioral mechanisms that determine the volume emissions produced by a car. The results show that an optimal fuel tax would provide drivers with appropriate incentives along all three margins and that only public information is needed for a fuel tax to be set optimally. In contrast, an optimal distance tax would require private information. Lastly, relative to the optimal fuel tax, a simple uniform fuel tax is shown to be progressive. Thus, being already deployed worldwide, a uniform fuel tax is an attractive second-best policy. These findings should be accounted for when designing new mechanisms to alleviate motor vehicle pollution.

    • "Driver education entails training drivers on fuel efficient driving styles [12], [15]. While this method has been shown to be effective [1], [15], it has been shown that over time, some drivers tend to depart from fuel efficient behavior [15], [16]. Furthermore, training a fleet of drivers is time consuming and costly. "

    ABSTRACT: Dependency of the transport sector on fossil fuels is encouraging a significant amount of research in to improving fuel efficiency in vehicles. Three primary techniques are identified for vehicle fuel efficiency improvement: 1) vehicle technology improvements such as drivetrain improvements, 2) traffic infrastructure improvements such as traffic flow management and route selection, and 3) driver behavior changes such as acceleration and deceleration profiles. Out of the 3 techniques, driver behavior changing has the least implementation cost and is able to provide immediate results. Thus, this paper presents a fuel efficient driving behavior identification and feedback architecture that is specific to fleet vehicles. The presented method utilizes historical data from fleet drivers on specific routes and generates fuel optimal velocity profiles that do not affect travel time. The identified velocity profile is the prompted to the driver via a low-cost plug-and-play style un-obstructive display. The display uses an intuitive and easily understandable visualization to prompt drivers on fuel efficient velocity. The presented architecture was tested on the Idaho National Laboratory (INL) bus fleet in real-world driving conditions and was shown to be able to increase the fuel economy by 9% and 20% in two different driving scenarios.

    • "Several studies have documented the short-term and long-term impacts of eco-driving training (e.g., af Wåhlberg, 2007; Beusen et al., 2009) and have evaluated the influence of after-driving and real-time feedback concerning driving style on an individual's driving behavior (e.g., Barth & Boriboonsomsin, 2009; Ericsson, Larsson, & Brundell-Freij, 2006). In brief, intervention studies showed positive short-and long-term effects of eco-driving training, but these effects shrink over time; some drivers ''forget'' what they learned during the intervention (e.g., af Wåhlberg, 2007; Beusen et al., 2009). There are no studies investigating the psychological aspects of eco-driving implementation, and only few studies have focused on motivation to practice eco-driving. "

    ABSTRACT: Eco-driving has well-known positive effects on fuel economy and greenhouse-gas emissions. Moreover, eco-driving reduces road-traffic noise, which is a serious threat to the health and well-being of many people. We investigated the psychological predictors of the adoption of eco-driving from the perspective of road-traffic noise abatement. The data came from 890 car drivers who participated in a longitudinal survey over four months. Specifically, we tested the effects of the intention to prevent road-traffic noise, variables derived from the theory of planned behavior (social norm, perceived behavioral control, and attitude), and variables derived from the health action process approach (implementation intention, maintenance self-efficacy, and action control) on the intention to practice eco-driving and on eco-driving behavior. The intention to prevent road-traffic noise was not linked to the intention to practice eco-driving. The strongest predictors of the intention to practice eco-driving were attitude and perceived behavioral control. The strongest predictor of eco-driving behavior was action control. The link between behavioral intention and behavior was weak, indicating that drivers have difficulties putting their intention to practice eco-driving into action. Therefore, intervention efforts should directly address and support the transition from intention to behavior. This could be accomplished by providing reminders, which help to maintain behavioral intention, and by providing behavior feedback, which helps car drivers to monitor their behavior.
