A study on perceived usefulness of Eco driving assistant systems in Europe

Assessing the usefulness of eco driving assistant systems is of high interest for system developers and researchers. This applies especially to systems which try to influence the driver’s behaviour in everyday situations. This paper presents results of a survey simultaneously conducted in eleven European countries with more than 5000 respondents aiming at collecting needs and requirements for future eco driving assistant systems. Such systems have the potential of changing driving behaviour in the long run for supporting a more fuel efficient driving and reducing emissions caused by motorized traffic. Three different driver assistant systems are considered covering inefficiencies in pre-trip, on-trip and post-trip situations. Each system is assessed according to the factors of perceived usefulness, the expected environmental impact and the user’s willingness to pay for it. The study will show that in general car drivers welcome the deployment of eco driving assistant systems and rate them as useful. It likewise demonstrates that the acceptance of additional costs for the user is very low

Nutzeranforderungen von Fahrerassistenzsystemen und C2X Applikationen mit dem Ziel CO2-Emissionsminderung: Ergebnisse einer europaweiten Studie im Rahmen des EU Projektes eCoMove

Die Verringerung der Emissionen des Straßenverkehrs ist auf Grund des stetig steigenden Mobilitätsbedarfs eine große Herausforderung. Hohes Einsparpotential von Kraftstoff und somit auch von verkehrsbedingten Emissionen wird einer effizienteren Fahrweise zugesprochen. Der Forschungsansatz des europäischen Forschungsprojekts eCoMove sieht vor, den Fahrer durch Einsatz von Assistenzsystemen dabei aktiv und nachhaltig unterstützen. Dabei kommen neben fahrzeugseitigen Innovationen ebenfalls Anwendungen zum Einsatz, welche Car2Car (C2C) und Car2Infrastructure (C2I) Kommunikation nutzen, um den Verkehrsfluss effizienter zu steuern. In einer Nutzerakzeptanzuntersuchung bewerteten europäische Autofahrer drei Fahrassistenzsysteme zur Reduzierung des Kraftstoffverbrauchs nach bestimmten Kriterien. Die Ergebnisse werden hier diskutiert. The reduction of traffic induced emissions is a major challenge considering the raising demand for mobility. A high potential for reducing fuel consumption and thus traffic emissions is seen in an improved driving behavior. The European research project eCoMove aims to support vehicle drivers in driving more efficiently using driver assistance systems. In the cooperative traffic system of eCoMove vehicle-to-vehicle and vehicle-to-infrastructure communication is used to organize traffic in a more efficient way. A user acceptance study was carried out in which European drivers were asked to rate three driver assistance systems aiming to improve the fuel efficiency according to certain criteria. The results will be discussed in this paper

Expect the unexpected: qualitative and quantitative tools and methods to detect unintended effects of transport policies

This paper is based on parts of Deliverable 2 of the European Project OPTIC (Optimal Policies for Transport in Combination, see DLR and KIT, 2010). It focuses on the development of an inventory of tools and methods for the early detection of unintended effects. Additionally, it deals with the question of when and where integrating assessment approaches is recommendable along the policymaking process. The inventory of tools and methods is done for mainly qualitative approaches (denominated as structurally open methods) and mainly quantitative approaches (denominated as structurally closed methods, more precisely EU models TRANSTOOLS and TREMOVE). A methodology is presented using examples that illustrate step by step the consideration of either structurally open or structurally closed methods focusing on the detection and the assessment of unintended effects. On the basis of these examples, recommendations are given when and where the consideration of different assessment approaches is most promising regarding the initially set policy objectives

Assessment of Transport Technologies: A Multi-Criteria Framework for Decision Making

Reducing greenhouse gas emissions has constantly been an objective in transport policy making. One possible approach to reach this goal is to increase fuel-efficiency. Restrictive emission policies have already led to vehicle technology improvements and thus reduced fleet emissions. Another possible way to reach emission reduction goals is to increase traffic efficiency by means of information and communication technologies. Smooth traffic, less stops and constant speeds are indicators for higher traffic effectiveness and decreasing transport emissions. Certain changes in traffic behaviour are necessary to reach these goals. The potential of fuel efficiency increase through changed driver behaviour is significant and advanced assistant systems can play an important role to improve it on a sustainable level. In several research projects assistant systems which help drivers to reduce their personal fuel consumption and thus lower the overall traffic emissions are evaluated. The type of recommendation given to the driver (e.g. about speed adjustment) relies here on the current traffic situation and is provided via visual, acoustic or haptic messages. The assessment of new technologies includes the evaluation of all kinds of effects a certain technology such as the driver assistant system may provoke. In several technology assessment approaches the conclusion has been that there is not a single best procedure that could be applied to any assessment objective. It is rather intended to consider all relevant effects and reduce the probability of wrong judgements about the outcome. Helpful for those making decisions later on whether these technologies should be realized or not can be a multi-criteria framework which includes technical and non-technical information retrieved during the assessment process. Such a framework is based on available data – which may be qualitative (user perception, expert judgement) or quantitative (traffic simulation, field test measurement) – and used to compare alternatives and assist in decision making. The multi-criteria analysis as a feasible method for technology assessment and aspects of uncertainty will be discussed

Requirements and motivators for private and commercial drivers: Deliverable 6.1.

The Validation and Evaluation sub-project of the eCoMove project groups a number of complementary activities including the core tasks to validate the functionality of the eCoMove system and applications, and to evaluate if the aimed reduction of 20% overall energy consumption can be achieved. Besides technical requirements a validation process also has to consider non-technical requirements of potential users of the eCoMove system which were in the focus of research for this deliverable

Driver Assistance Systems for Transport System Efficiency: Influencing Factors on User Acceptance

A major success factor for the implementation of Intelligent Transportation Systems (ITS) is the knowledge about the user's reaction and response to such technologies. The objective of each development process is to achieve a broad acceptance among those using the system. User acceptance is a key success factor, so it should be taken into account in early development stages. This applies especially for technical solutions requiring frequent interactions, for example to influence the driver's behaviour towards a more efficient driving style. The complexity of developments in the field of ITS raises the question: at what point do users start feeling overloaded and are no longer able to handle all functionalities, ultimately rejecting to use them? A European-wide study was carried out (N = 5807) focusing on drivers’ perception towards cooperative systems that offer assistance on fuel efficiency. The Advanced Driver Assistance Systems (ADAS) used in the study, have the potential to change driving behaviour in the long-term and thus have a sustainable impact to reduce fuel consumption and traffic emissions. ADAS functionalities provide up-to-date traffic information which is disseminated by traffic management to help traffic flow in a more energy efficient way. Six ADAS functions were assessed in pre-, on-, and post-trip driving situations. The chosen research framework was used to compare the users’ perception using a set of relevant acceptance factors that were developed in this study. The results showed significant effects between acceptance factors and the influencing variables. The interrelations between acceptance factors were analysed using a research model developed in this study. The concept proves to be suitable for studying acceptance of ITS solutions aiming to save fuel

Perceived usefulness of eco-driving assistance systems in Europe

Assessing the perceived usefulness of eco-driving assistance systems is of high interest for system developers and researchers in the development stage of such systems. This applies especially to systems that try to influence the driver’s behaviour in everyday situations and generating their greatest benefit if regularly used. This study presents results of a survey simultaneously conducted in 11 European countries with more than 5000 respondents aiming at collecting needs and requirements for future eco-driving assistance systems. Such systems have the potential of changing driving behaviour in the long run for supporting a more fuel-efficient driving and reducing emissions caused by motorised traffic. Three different driver assistance systems are considered covering inefficiencies in pre-trip, on-trip and post-trip situations. Each system is assessed according to the factors of perceived usefulness, the expected environmental impact and the user’s willingness to pay for it. The study will show that in general car drivers welcome the deployment of eco-driving assistance systems and rate them as useful. It likewise demonstrates that the acceptance of additional costs for the user is very low
