The objective of this paper is to explore what motivates consumer intention and willingness to pay for green transportation. The model is based on the theory of planned behavior and explains the relationship between consumer attitude, perceived behavioral control and peer pressure on intention and willingness to pay for a t-shirt that was transported using energy efficient fuel. Data from a survey of U.S. consumers is analyzed. Results suggest consumer attitude and peer pressure are positively associated with intention which is positively associated with willingness to pay. High levels of consumer attitude, perceived behavioral control and intention suggest a positive outlook for organizations investing in green transportation initiatives. Results also suggest a need for organizations and government to market and educate consumers and citizens about the positive implications of green transportation and using energy efficient fuel. 相似文献

文中采集中国2007年的统计数据,根据Leontief投入产出理论,以国民经济体系中42个产业部门为对象,分析了建筑业与各产业的后向关联性。结果表明,建筑业每增加一个单位的产出,将对其他产业部门产生0.7686个单位的直接需求拉动,直接与间接需求拉动总和则为2.4869个单位,建筑业对完全关联密切的产业消耗量占总消耗量的比例为73.27%,需求较为集中。供给方面,建筑业对第二产业的供给依赖最大,达81.37%,表明我国建筑业依然处于物资消耗的较粗放扩张阶段。 相似文献

Various models that incorporate concepts from Non-Cooperative Game Theory (NCGT) are described in the transport literature.
Game Theory provides powerful tools for analysing transport systems, but these tools have some drawbacks that should be recognised.
In the current paper we review games that describe transport problems and discuss them within a uniform context. Although
the paper does not introduce new tools, it presents insights concerning the relations between transport models and games.
We divide existing games into groups and show that some common features characterise multiple games. We distinguish between
games that make a conceptual contribution and games that are suitable for application. Compact or symmetric game structures
make remarkable observations but often do not support actual decision-making. Less aesthetic formats, most of which are Stackelberg
games between authorities and travellers, are stronger as instruments that assist in determining real-life policies; these
formulations can be treated by practitioners as mathematical programs with equilibrium constraints and not as games.

Different models using belief functions are proposed and compared in this article to share and manage imperfect information about events on the road in vehicular networks. In an environment without infrastructure, the goal is to provide to driver the synthesis of the situation on the road from all acquired information. Different strategies are considered: discount or reinforce towards the absence of the event to take into account messages agings, keep the original messages or only the fusion results in vehicles databases, consider the world update, manage the spatiality of traffic jams by taking into account neighborhood. Methods are tested and compared using a Matlab™ simulator. Two strategies are introduced to tackle fog blankets spatiality; they are compared through an example. 相似文献
