自然灾害下的公交疏散路线模型

自然灾害通常给社会带来巨大的危害,以自然灾害所引起的紧急情况作为研究背景,进行应急交通疏散预案研究。讨论自然灾害下的应急交通疏散问题并重点探讨疏散路线设计、疏散时间计算,用以达到在自然灾害发生前将人们转移至安全地点的目的。利用公交车作为疏散工具,将公交疏散路线问题归为带时间窗的车辆路径问题(VRPTW),建立基于VRPTW的公交疏散路线模型,以某地区为案例利用TransCAD软件中的车辆路径功能(VRP功能)设计疏散路线,得到标有疏散时间和疏散路线的地区图形,并最终计算得到每条路线的疏散时间、疏散人数、公交车数等信息。

Usage‐based insurance and its acceptance: An empirical approach

This study aims to explore the motor insurance market's attitude towards usage‐based insurance (UBI), and thus its readiness for a launch in the near future. Data on client perception was collected using a structured questionnaire. On the basis of this, an initial selection of factors, other than income, that could influence the declared attitude of drivers was demonstrated showing that it is primarily dependent on certain demographic characteristics like their age, sex, or place of residence. A strong relationship was also demonstrated with respect to the intensity of the vehicle's use, to the amount of the insurance premium they have paid, and to the self‐assessment of the respondents' driving skills. Clients are likely to accept the concept of UBI once implemented, but that they are not ready yet to give up the traditionally used methods of premium calculation. Their attachment to discounts granted can be very strong in particular to the no‐claims bonus.

我国汽车服务贸易发展现状分析

随着我国加入WTO,汽车服务贸易领域对外开放的步伐得以加快,如果不能及时建立健全既适合我国国情,又能与国际市场运作理念和技术水平接轨的汽车服务贸易体系,将会对我国汽车工业的发展产生极其不利的影响。本文通过对我国汽车服务贸易的发展现状的分析,探究在新汽车贸易政策下我国开展汽车服务贸易的战略选择。     

Cost savings of using a marketable permit system for regulating light-duty vehicle emissions

In the USA, each individual vehicle is required to meet uniform per-mile emission standards. The uniform standard system does not allow vehicle manufacturers flexibility in achieving overall emission reduction goals for motor vehicles. The system provides manufacturers with little or no incentive to control vehicle emissions beyond what is required. In this paper, an incentive-based marketable permit system is proposed to replace the uniform standard system. Under the marketable permit system, vehicle manufacturers are required to meet corporate average emission standards; they are allowed to buy or sell vehicle emission reduction credits among themselves to meet corporate average standards; and they are allowed to bank vehicle emission reduction credits that are accumulated in earlier years and to use the credits for meeting average standards in later years. It is estimated in this study that relative to the current uniform standard system, the marketable permit system can reduce vehicle emission control costs by $150 to $400 million per year in California, or 13–30% of the costs currently spent on vehicle emission control.     

汽车装配物流输送机系统结构的优化设计与应用

通过对输送机承载小车轴承提前失效现象的理论分析,得出其主要失效原因是轴承自身强度不足及润滑不良。由此症结寻求对策：设计非标整体轴承滚轮,辅以油嘴油槽加注油脂以改善轴承润滑,从而达到延长轴承使用寿命的目的。     

Recreation vehicles : A perspective

The growth and popularity of recreation vehicles in the United States and other countries has implications for the travel and tourism industry. Owners of these vehicles require no separate lodging facilities while traveling and rarely patronize hotels or motels. They often perceive that they spend less for their vacations by staying at travel parks and campgrounds, but survey results and comparative cost analysis reveal that they spend more than automobile travelers when total fixed and variable costs are taken into account. Recreation vehicle (RV) preferences by income category suggest alternative modes of recreation travel and a vacation life style which has considerable appeal. This “RV life style” is characterized by a strong desire to experience the outdoors and socialize with other campers while still retaining the comforts and conveniences of a familiar domicile. Limiting characteristics include the provincial nature of recreation vehicle travel and the impact of mandatory fuel conservation measures.
