燃料电池轿车车内噪声特性试验分析

在半自由场消声室内四轮转毂试验台上对燃料电池轿车进行了声振特性测试,采集了不同车速工况下车内噪声信号及运动部件的振动加速度信号。分析了不同车速工况下车内噪声的分布状况及主要频率成分。通过信号分析表明,车内噪声来源于驱动电机总成和燃料电池系统中的氢泵、风机,产生的噪声通过空气直接传到车内,同时引起车身板件振动并向车内辐射噪声。根据样车的结构特点提出了减振降噪措施。     

城市客运交通走廊判定方法研究

如何正确判定城市客运交通走廊是进行城市大运量客运交通方式规划首先需要解决的问题。通过分析城市客运交通走廊对交通源和交通方式的集聚效应特点,提出采用效应场和场中介质的概念来模拟交通走廊对交通流和交通源的吸引作用。应用衰减函数或磁感函数作为效应场函数模拟分析城市客运交通走廊对附近范围产生的集聚效应,采用人口密度、出行生成密度或潜力密度作为介质函数来表现走廊附近范围的土地利用形态,提出了一种直接根据用地来确定城市客运交通走廊的方法。     

Planning and Evaluation of Passenger Ferry Service in Hong Kong

A predominant observation in Hong Kong is the continuous loss in ferry patronage. There are two main reasons for this: poor level-of-service and better competitors. New roads, bridges, and tunnels are serving the buses, and to some extent the railways; whereas the investment in ferry terminals is relatively at a lower level. On the one hand, there is no need to promote the ferries in a free market environment; but on the other hand, the ferries have the best safety record, can only relieve some traffic congestion and need water access that is one of the characteristics of Hong Kong. The goal of this paper is to design a planning approach combined with an evaluation procedure on how to make the best use of the existing water and pier resources in Hong Kong through the provision of commercially viable ferry services. The approach used covers the impact of future developments planning up to 2006 comprising all public transport modes in Hong Kong (heavy rail, metro, bus, and ferry). The planning tool is based on a newly developed multi-objective evaluation method in order to assess the ferry routes with scientific, practical, and simplified analyses for future use. This assessment is applied to the existing ferry routes and candidate routes and can also be carried out on an individual route basis or on a given set of routes. The objective functions set forth analytically in the evaluation method take into account the interests of the three participants: the passengers, the operators and the government. The proposed ferry network design formulation and the suggested new ferry routes will have a positive impact on changing the ferry system’s image in Hong Kong.

An integrated assessment of alternative land-based passenger transport policies: A case study in Tenerife

Over recent decades, there have been numerous cases of land-based transport policies that have lacked clear and coherent strategies. This has not only hampered the resolution of issues like road congestion, but has also created new ones (e.g. strong social opposition to new train infrastructures). The absence of such strategies highlights the need for long-term transport policies with a wider vision of the issues, since land-based transport cannot be considered from just a technical perspective.The main objective of this article is to implement a participatory integrated approach to facilitate the understanding of land-based passenger transport governance issues on Tenerife, in the Canary Islands. Relevant policy issues and alternatives are identified by the stakeholders involved. The inclusion of stakeholders in the assessment process is crucial to frame transport governance issues appropriately and to define and assess plausible policy alternatives. This assessment process even included a final step of validation of the results by stakeholders to foster discussion among them about transport issues and policy alternatives.Finally, due to the obstructive role played by some stakeholders in influencing past transport policies, an analysis of possible coalitions among stakeholders is also discussed.     

基于数据融合的公交客流规模测算方法

公交客流规模测算往往存在调查成本受限和准确度要求较高的矛盾.提出基于公交IC卡历史数据与人工补充调查数据的数据融合测算方法,以准确推算公交客流规模.首先根据公交线路的基本属性,采用聚类分析方法划分线路类型,从每一类中选择具有代表性的线路.基于IC卡数据分析公交客流时变特征,运用有序样本聚类Fisher算法将线路小时刷卡量进行聚类分析.划分刷卡量相似时段,进而采用优化方法确定调查抽样率,确定相应的调查车辆进行人工补充调查,最终经过数据融合计算获得公交客流规模.基于上海市某辖区IC卡数据进行案例分析,测算得到三类公交线路的日均客流量.     

洋山深水港区工程码头及接岸结构选型

洋山深水港工程依托外海岛礁地形通过填海造地形成港区,其关键技术之一就是采用何种码头及接岸结构型式才能阻挡软土地基上平均23～26 m高回填土的作用。文章重点介绍一期工程码头及接岸结构在复杂的自然条件、较高的使用要求、恶劣的施工条件以及较短施工周期等条件下,按照有利于工程快速施工、有利于陆域形成以及有利于控制质量的原则,提出采用高桩码头结构 斜顶桩板桩承台驳岸结构型式。实施效果表明:该结构型式适合洋山港区的地质条件和建设条件,有利于港区的陆域形成及后续工程的推进,技术风险小;后方高回填土对码头结构没有影响。
