Green Driver: Travel Behaviors Revisited on Fuel Saving and Less Emission (original) (raw)

DRIVERS' ADAPTIVE TRAVEL BEHAVIORS TOWARDS GREEN TRANSPORTATION DEVELOPMENT: A CRITICAL REVIEW

The transportation professionals integrated the concept Green in various dimensions of transportation, such as, green vehicle, green highway. The current study has established a new dimension to green transportation, which is called Green Driver as whom substantially contributes to less emission and fuel consumption, and higher-safety. The research established the driver's Green Adaptive Travel Behaviors (GATB), in particular, that is referred to voluntary personal and lifestyle behaviors on less energy consumption and emission. The methodology was designed into two phases. Phase one was to investigate driver's GATBs through systematic literature review process and content analysis method. The second phase was to verify greenery value impact (GVI) of the finalized list of drivers' GATBs through an expert input study and Grounded Group Decision Making (GGDM) method. Total twenty six (26) GATB factors have been determined. Amongst, the factor 'F27-Dangerous overtaking' has received the highest value (97%) followed with 'F3-Slow once realizing bike lanes for cyclist crossing' (91%). In contrast, 'F4-Realize visual Obstacles to manage the speed' and 'F21-Brake with smooth deceleration' has received the lowest value (77%) among other factors. Two of the initial factors;'F5-Use traffic calming devices' (55%), and 'F24-Change highest possible gear' (69%) could not reach the 70% saturation; hence, they have been dropped from the list of GATB factors. Indeed, the GATB efforts are not limited to technology and practice; but also can include education and enforcement to driving regulations in order to interconnect driver, technology, environment, and vehicle. The research concluded with an innovative technique used as the decision support tool to evaluate the greenery grade of any individual driver on committing to less emission, less fuel consumption, and higher safety in traveling. As future study, the Green driver behaviour index assessment model will be developed based on this study outputs.

Review of Driving Behavior Towards Fuel Consumption and Road Safety

2018

One of the main concerns for automobile researchers is establish a driving method that is efficient to the engine and ensures road safety. Most studies categorized driver’s behavior based on aggressiveness while driving. It was found that aggressive drivers tend to provoke fast start and quick acceleration, driving at high engine revolution, and causing sudden speed change that are prone to road accidents. On the other hand, eco-driving which consists of gentle acceleration, coast-down deceleration, maintaining a steady speed and avoidance of high speed is much safer than the aggressive driving. At the same time smooth, experienced pattern in the eco-driving consumes lesser fuel in a statistically significant way. Driver’s aid system in modern cars have been invented to assist the driver into eco-driving were claimed to be effective. However, in the absence or failure of such system, drivers are suggested to drive by maintaining steady speed, avoiding sudden stop and harsh accelerat...

The Effect of Ecodrive Program on Driving Behavior and Fuel Economy of Passenger Cars in Tokyo

Journal of the Eastern Asia Society for Transportation Studies, 2011

Ecodrive or Ecodriving is a driving technique designed to improve fuel economy, reduce CO2 and lessen the adverse impacts of road transport on the environment. This study investigates the effects of the Ecodrive program on candidate drivers by looking into their driving behavior (psychological and non-psychological factors) as well as taking into consideration the vehicle parameters used during Ecodrive training. There are twenty-seven drivers with their vehicles equipped with on-board data-logging equipment that serve as subjects of this study. The drivers were given sets of questionnaires for them to fill-in before and after training. Questionnaire data and actual driving data were analyzed using Cronbach‟s Alpha and Regression. The study has successfully recorded and analyzed the effects of Ecodrive program on driver behavior with respect to fuel efficiency. The study also showed fuel efficiency, improvement of the program, improvement during idling stop and improvement during dr...

Eco-driving: behavioural pattern change in Polish passenger vehicle drivers

E3S Web of Conferences, 2018

In Poland, as in the rest of Europe, air quality depends primarily on emissions from municipal, domestic and road transport sources. The problems of appropriate air quality are especially important within urban areas due to numerous sources of emissions being concentrated in relatively small spaces in both large cities and small/medium-sized towns. Due to the steadily increasing share of urban population in the overall number of population, the issue of providing clean air will over the years become a more significant problem for human health, and therefore a stronger incentive to intensify research. The key challenge faced by a modern society is, therefore, to limit harmful substance emissions in order to minimise the contribution of transport to pollution and health hazards. Increasingly stringent emission standards are being imposed on car manufacturers; on the other hand, scant regard is paid to the issue of drivers, i.e. how they can help reduce emissions and protect their life...

sustainability Driving Behaviour and Sustainable Mobility-Policies and Approaches Revisited

Sustainability, 2018

Climate change is receiving increasing attention in recent years. The transportation sector contributes substantially to increased fuel consumption, greenhouse gas (GHG) emissions, and poor air quality, which imposes a serious respiratory health hazard. Road transport has made a significant contribution to this effect. Consequently, many countries have attempted to mitigate climate change using various strategies. This study analysed and compared the number of policies and other approaches necessary to achieve reduced fuel consumption and carbon emission. Frequency aggregation indicates that the mitigation policies associated with driving behaviours adopted to curtail this consumption and decrease hazardous emissions, as well as a safety enhancement. Furthermore, car-sharing/carpooling was the least investigated approach to establish its influence on mitigation of climate change. Additionally, the influence of such driving behaviours as acceleration/deceleration and the compliance to speed limits on each approach was discussed. Other driving behaviours, such as gear shifting, compliance to traffic laws, choice of route, and idling and braking style, were also discussed. Likewise, the influence of aggression, anxiety, and motivation on driving behaviour of motorists was highlighted. The research determined that driving behaviours can lead to new adaptive driving behaviours and, thus, cause a significant decrease of vehicle fuel consumption and CO 2 emissions.

Ecological Driving Style – Factor for Environmental Protection

The analysis represents a trend of increasing road transport in Bulgaria, augmentation of noxious gases emissions and noise, which influence negative on the environment and reduces the quality of life. This is a consequence not only from the increased number of vehicles, their inefficient use, urban driving in heavy traffic, but also by insufficient quality of basic education and in the subsequent training of drivers. necessary is to encourage the use of alternative and renewable fuels and technologies, and expanding the elements of eco-driving and behaviour. The report performs a comparative analysis between different models of training and examination of drivers in EU countries and in Bulgaria, also including the compulsory elements of eco-driving. Based on our research with all examiners from different regions of the country and a group of instructors we specify the main components of eco-driving and elements of the ecological style of driving. In the questionnaires, which were offered to respondents, the items include environmentally driving and the development of competencies for self-assessment in the personal choice of mode of movement, consistent with road conditions and situations, the safety of other participants and protection of the environment. Based on the data and conducted interviews with experts-examiners and driver instructors suggest the implementation of multi-stage model of driver training, accompanied driving for the beginners and with elements of environmental protection in a basic preparation, in an upgrade training, and at exam for obtaining a license. The emphasis is on realization of 3, 4 and 5-th level of GDE-matrix for drivers training, the development of defensive and ecological driving style, which will significantly reduce the harmful emissions, fuel consumption, maintenance costs of vehicles and will improve health status of the participants in road traffic and the population in general.
