This paper constructs an additive two-stage network DEA (data envelopment analysis) model with consideration of undesirable outputs and shared inputs. Following the triple bottom line standard of sustainability, we calculate both the overall and sub-stage sustainability performance of railway transportation in China from 2002 to 2013, from the aspects of economy, environment and society. The re...

Some aspects are illustrated of energy conversion processes during the operation of electric railway vehicles with traction induction motors, in order to support transport systems’ sustainability. Increasing efforts are being expended to enhance the sustainability of transportation technologies and systems. Since electric drive systems are used with variable voltage variable frequency (VVVF) in...

Periodically, new major forces dramatically reshape the business world. Just as globalisation, the information technology revolution and the knowledge economy have been doing for the past two decades. In the early part of this twenty-first century, the most important pressures facing businesses worldwide, especially those in the developed world, is arguably the need for integrating sustainabili...

Traditionally, the foremost concern among transportation engineers has been the safety and reliability of major infrastructure components. Until recently, sustainability has not been included in most infrastructure systems on any level. However, the engineering community, along with society as a whole, is realizing the importance of sustainability-oriented infrastructure systems. Yet incorporat...

A sustainable economy is sensitive to economic, social and environmental constraints. Sustainability requires more efficient, equitable, and environmentally sensitive transport. This cannot be achieved simply by improving the efficiency of vehicle designs or traffic management. It requires changes in the way we think about transportation, and how we identify and evaluate solutions to transport ...

Sustainability performance and efficiency is an important topic in transportation and for forwarders. This is shown, for example, by the fact that major logistics service providers LSP publish sustainability reports, often within the annual legal business report. However, in depth research is missing regarding the efficiency of forwarders regarding the established triple bottom line approach fo...

Global warming and energy security are the main drivers for innovation towards alternative and sustainable energy solutions. The prevailing notion is that eventually technological innovations will solve the problem. However, scenario studies point out that deep change processes in institutions, life styles, and values will be necessary in addition to technological innovations. Moreover, there a...

Lignocellulosic biomass feedstock transportation bridges biomass production, transformation, and conversion into a complete bioenergy system. Transportation and associated logistics account for a major portion of the total feedstock supply cost and energy consumption, and therefore improvements in transportation can substantially improve the cost-competitiveness of the bioenergy sector as a who...

As an important part of daily economic activities, freight transportation produces various pollutions during the process, which will have a negative effect on sustainable development environment. In this paper, entropy weight technique for order preference by similarity to ideal solution (TOPSIS) combination method was used specific calculations, in judge whether is environmentally sustainable....
