“…Indeed, using lightweight materials for vehicle manufacturing has been significantly successful compared to using biofuels (5%) [161]. The light-weighting policy unanimously has fewer trade-offs in adoption of novel and new materials and technologies [160,165]. Lightweight vehicles use aluminium, magnesium alloy, carbon-fibre reinforced polymer (CFRP) and other materials, which have lower GHG and CO 2 emissions over vesicle's life-cycle than iron and steel [165][166][167].…”

Lightweight vehicles use aluminium, magnesium alloy, carbon-fibre reinforced polymer (CFRP) and other materials, which have lower GHG and CO 2 emissions over vesicle's life-cycle than iron and steel [165][166][167]. For example, replacing steel Mg has led to 5.7% weight reduction that decreases the vehicle fuel consumption and life cycle emissions by 1.3% and 0.8%, respectively.…”

Driving Behaviour and Sustainable Mobility—Policies and Approaches Revisited

et al. 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.

“…Exergetic evaluation of H 2 FC buses have also been conducted [16]. Work on effects of light weighting has also been performed for automotive applications [17,18] as well as dealing with the challenges for modelling and integrating of light weighting into concept design [19]. However, there are no studies available on the effects of light weighting in relation to buses in general and H 2 FC buses in particular.…”

Hydrogen fuel cell (H 2 FC) buses operating in every day public transport services around Europe are assessed for their sustainability against environmental, economic and social criteria. As part of this assessment the buses are evaluated against diesel buses both in terms of sustainability and in terms of meeting real world requirements with respect to operational performance. The study concludes that H 2 FC buses meet operability and performance criteria and are sustainable environmentally when 'green' hydrogen is used. The economic sustainability of the buses, in terms of affordability, achieves parity with their fossil fuel equivalent by 2030 when the indirect costs to human health and climate change are included. Societal acceptance by those who worked with and used the buses supports the positive findings of earlier studies, although satisfactory operability and performance are shown to be essential to positive attitudes. Influential policy makers expressed positive sentiments only if 'green' hydrogen is used and the affordability issues can be addressed. No "show-stopper" is identified that would prevent future generations from using H 2 FC buses in public transport on a broad scale due to damage to the environment or to other factors that impinge on quality of life.

“…In previous studies, physical and empirical methods were usually considered in modeling fuel consumption and emission. It was found that, vehicle fuel consumption and emission rates were usually associated with cruise speed, drivers' acceleration aggressiveness, road grade [1][2][3][4], traffic control strategies [5], and characteristics of a vehicle, e.g., weight [6][7][8].…”

This paper investigates the factors affecting drivers' vehicle fuel consumption efficiency, which was defined as the daily average fuel consumption for a unit of driving mileage. Based on the long-term Controller Area Network (CAN) data collected from private cars during 10 months in Toyota City, Japan, we explored the relationships between drivers' fuel consumption efficiencies, and factors including drivers' characteristics, car attributes, date-specific environmental attributes, and travel behavior. Furthermore, a multi-level model was applied to explicitly incorporate the effects of individual-specific, date-specific, and observation-specific unobserved factors. According to the estimation results, it was found that, on working days, model fit was significantly enhanced by incorporating all three error terms. Several findings regarding the relationships between observed factors and drivers' fuel consumption efficiencies were also obtained.
