新能源汽车知识产权的研究

文章首先分析了丰田的混合动力轿车专利状态及市场地位,混合动力汽车销量与其专利申请数量的关系,然后分析本田、日产、通用、欧洲汽车公司及中国汽车公司的混合动力汽车专利申请数量,研究了汽车公司采取的混合动力汽车专利战略及其实际案例。最后建议在企业的新能源汽车项目中,要充分研究国内外新能源汽车的专利地图,设计自主知识产权的新能源汽车的技术方案,从而避免产品上市后,遭遇竞争对手的专利起诉问题。     

滨海新区交通组成及其特性研究

天津滨海新区由于天津港的存在,属于典型的集疏港交通,重载、超载普遍存在,这给道路、桥梁造成严重影响,必须对其进行深入的调查研究。通过对滨海新区道路交通量的调查和对各种类型车辆重载、超载的测试,对滨海新区交通组成及其交通特性进行了研究,为滨海新区及类似地区道路、桥梁结构设计提供技术支持。     

The New Zealand experience in restructuring road administration New Zealand road reform

Reform in the public sector in New Zealand saw the abolition of the Ministry of Works and Development in 1988, with the commercial activities being transferred into a Government owned company. Further reform saw the client function of roads transferred initially into the Ministry of Transport and then into an independent Crown agency known as Transit New Zealand. Transit New Zealand is led by an Authority of six members, appointed by the Government, and it administers the strategic (national) road network (10,500 kilometres).In 1996 a separate funding body, Transfund New Zealand, was established to distribute funds to Transit New Zealand and local authorities. Transfund New Zealand is funded through a share of the petrol excise, all vehicle registration and licensing fees and all road user charges (an axle-weight/distance charge levied on diesel vehicles, especially trucks). These revenues are paid into a dedicated National Roads Fund, which allows a measure of transparency in funding the road system. The reforms in New Zealand have resulted in large efficiency gains, with no measurable lowering in level of service.The road agency of the future is discussed, along with possible changes in road management.     

一种新型冷试工艺线束快捷检测台的设计及应用

目前汽车行业大部分主机厂同一款发动机会匹配不同车型的整车,导致同一款发动机需要匹配多款不同的整车线束,为保证发动机厂冷试、热试工位的便捷性、一致性,通常会采用工艺线束进行测试,工艺线束针脚、接头等为易损件,且工艺线束故障为冷试、热试工位触发频率较高的问题,因此,检测工艺线束的质量成为保证生产效率的高优先级事项.文章以某...

A NEW URBAN FORM AND ITS INNOVATIVE TRANSPORTATION STRATEGY TO ACCOMMODATE URBAN GROWTH

If we are to accommodate the rate of urban growth which North America will face in the first half of the twenty-first century, it is the contention of this paper that we must build new cities, not new towns, beyond commuting distance of existing cities. These can be located in open countryside on virgin land, or they can grow around existing small towns, all in conjunction with the construction of an innovative personal transportation system. In this paper a hexagonal modular structure, in which self-contained urban units can be combined and added to over time, is proposed as a new urban form and AVCS maglev — which will serve the new cities efficiently — is proposed as a key transportation strategy.     

Role of the built environment on mode choice decisions: additional evidence on the impact of density

Density is a key component in the recent surge of mixed-use neighborhood developments. Empirical research has shown an inconsistent picture on the impact of density. In particular, it is unclear whether it is the density or the variables that go long with density that affect people’s travel behavior. Many existing studies on density neglect confounding factors, for example, residential self-selection, generalized travel cost, accessibility, and access to transit stations. In addition, most still use a single trip as their observation unit, even though trip chaining is well recognized. The goal of this paper is to assess the role of density in affecting mode choice decisions in home-based work tours, while controlling for confounding factors. Using the dataset collected in the New York Metropolitan Region, we estimated a simultaneous two-equation system comprising two mutually interacting dependent variables: car ownership and the propensity to use auto. The results confirm the role of density after controlling for the confounding factors; in particular, employment density at work exerts more influence than residential density at home. The study also demonstrates the importance of using tour as the analysis unit in mode choice decisions. The study advances the field by analyzing the role of the built environment on home-based work tours. New knowledge is obtained in the relative contribution of density vs. a set of correlated factors, including generalized travel cost, accessibility, and access to transit stations.
