城市发展与轨道交通建设

轨道交通建设发展是破解交通拥堵、交通污染、绿色出行环境差和停车难等城市病的有效途径。在轨道交通大发展机遇期,有必要探讨如何科学规划城市轨道交通系统,促进城市集约发展和改善城市交通状况。研究总结城市交通的内涵,即城市形成和发展中的内在要素,提出城市交通应服务于人的需求、组织城市高效可持续运行。从车辆技术成熟度与国产化水平、轨道交通制式多样化、轨道交通规划建设规模与城市形态和发展阶段的适配性、认证和标准体系、交通功能与城市功能融合的一体化土地开发、多模式公共交通衔接换乘等角度出发,梳理发展现况并归纳问题及症结。重点针对结合市情的轨道交通基础性问题,就科学规划城市和都市圈的轨道交通系统提出指导思想和具体建议。     

荷兰海军APAR多功能雷达系统及其开发经验

为充分发挥多功能优势,APAR雷达采用了高效控制手段,对雷达信号收/发时间和能量进行综合管理,综合平衡二者系统资源开支。APAR雷达波形设计还综合考虑了包括作战需求、接收信号特征、技术特征和参数等在内的各种因素。APAR雷达在系统设计、系统工程、详细设计与评估测试等方面均进行了总体规划,并很好地吸收了已有的技术积累,保证了系统最终成功。     

浅谈新常态下海员的现状与可持续发展

海员是我国从海洋大国向海洋强国转变的中流砥柱,他们为发展国民经济、保证航运安全和扩大对外开放做出了巨大的贡献。但是从当前形势来分析,我国对海员的教育培训力度和关怀力度却远远跟不上海洋经济的发展。文中主要指出我国海员目前所面临的发展现状,结合国外海员的发展模式及可吸取的经验,对我国海员的可持续发展做出较为全面的策略探讨。     

近郊小城市交通发展策略研究——以成都市新繁镇为例

城市发展有它内在的规律性,中小城市特别是近郊小城市交通发展不能照搬大城市经验,应找到一条实事求是的自身发展路径。在新型城镇化和经济发展新常态对城镇化质量提出新要求的背景下,以成都市近郊小城市新繁镇为例,从机动化水平、交通模式、道路网络与交通管理等方面系统梳理近郊中小城市交通现状特征和发展面临的问题,分析交通需求的变化趋势,建立近郊小城市交通组织的分析框架,在此基础上,提出未来交通发展的重要策略。     

可持续交通——各方观点和长期挑战

从交通研究者和实践者的角度出发,以可持续交通这一概念为中心展开讨论。可持续交通宽泛地反映了可持续发展在交通领域的原则。随着可持续性这一概念的外延逐渐扩大,在它的定义、应用和价值取向上出现了不同观点。着重讨论可持续交通,以及如何理解和运用可持续交通,包括:1)将可持续性或者可持续发展作为一个整体的概念,包括关于可持续性的不同方法和定义之间的冲突;2)对可持续交通以及交通领域对其理解的探索;3)使用指标来实现可持续性的应用。然后识别了通往可持续交通之路的若干挑战,包括缺乏清晰定义、可持续性的固有冲突、可持续发展的跨领域本质、各种工作框架和指标体系、可持续发展的政治因素和交通领域实践中的不同观点。基于在该课题上的研究积累,总结解决这些问题的工作框架,提出因地制宜、注重结果、整体的方法来解决可持续交通中的挑战。     

Highway voting system: Embracing a possible paradigm shift in traffic data acquisition

The integration of internet and mobile phones has opened the door to a new wave of utilizing private vehicles as probes not only for performance evaluation but for traffic control as well, gradually replacing the role of traffic surveillance systems as the dominant source of traffic data. To prepare for such a paradigm shift, one needs to overcome some key institutional barriers, in particular, the privacy issue. A Highway Voting System (HVS) is proposed to address this issue in which drivers provide link- and/or path-based vehicle data to the traffic management system in the form of “votes” in order to receive favorable service from traffic control. The proposed HVS offers a platform that links data from individual vehicles directly with traffic control. In the system, traffic control responds to voting vehicles in a way similar to the current system responding to prioritized vehicles and providing the requested services accordingly. We show in the paper that the proposed “voting” system can effectively resolve the privacy issue which often hampers traffic engineers from getting detailed data from drivers. Strategies to entice drivers into “voting” so as to increase the market penetration level under all traffic conditions are discussed. Though the focus of the paper is on addressing the institutional issues associated with data acquisition from individual vehicles, other research topics associated with the proposed system are identified. Two examples are given to demonstrate the impact of the proposed system on algorithm development and traffic control.     

Career development for women in maritime industry: organisation and socialisation perspectives

For centuries, the maritime industry has been a recognised place in society dominated solely by men, and even though there were women involved, they were mostly on the periphery. This research aims to fill the gap of women’s career development in this field, by investigating the relationships among the degree of organisational socialisation, women’s workplace culture, and the career development of women in the maritime workplace. The analyses are conducted with the structural equation model with 202 valid questionnaires. The results indicated that women’s workplace culture has a significantly negative relationship with the degree of organisational socialisation, and then in turn, it has a significantly positive relationship with women’s career development in the maritime industry. Finally, the results also indicate that the mediating effect of organisational socialisation existed between women’s workplace culture and women’s career development. According to the empirical analysis, this study makes conclusions as well as suggestions for the maritime enterprises as the reference for human resource management.     

悉尼与中国城市公共交通绩效的比较研究

为完善悉尼市城市公共交通优先发展政策体系，实现悉尼市“可持续城市交通”愿景，借鉴中国“公交都市”示范项目的指导方针和指标体系，建立了一个基于公共交通绩效水平的评估指标体系，利用中国“公交都市”示范项目数据和悉尼市公共交通运营开放数据，分别计算了各城市的公共交通绩效水平。将悉尼市与中国“公交都市”示范项目试点城市的公共交通发展水平进行了比较研究。结果表明，悉尼市现有交通运输模式为主要依赖小汽车方式出行，虽然悉尼市在促进交通方式转变和新技术应用方面取得了一些进展，但其整体的公共交通服务水平远落后于中国“公交都市”示范项目试点城市。通过借鉴中国城市在“公交都市”示范项目实践中的经验，结合悉尼城市交通发展战略与规划，明确了悉尼市出台“从依赖小汽车出行转变为公共交通优先出行”导向政策的必要性，并提出了多项促进城市公共交通优先发展的政策建议，用以支持悉尼市实现“世界上最宜居城市之一”的发展目标。     

Integrated Transport System of the South-Moravian Region and its impact on rural development

It is generally presupposed that the infrastructure and availability of services of general interest (like schools, medical care, social services and also public transport) impact on present demographic development in rural areas, namely depopulation and aging. Such services affect the quality of life of local people and sometimes they perform a vital necessity. It is possible to say that the absence of the mentioned services should be compensated by an effective system of public transport. In other case, especially those people who are not able to use individual cars due to the age, health, legal conditions or financial situation are bequeathed on an assistance of the family or neighbors or they stay cut off and excluded. This paper is aimed at the verification of the presupposition in the case of the South-Moravian Region – NUTS 3 region occupying the south-eastern part of the Czech Republic, bordering with Austria and Slovakia. The research method lies in analysis of the frequency, travel time and fare of public transport system and its comparison with demographic development in rural areas, especially in the peripheral ones. The results are discussed in view of the system of central places in the region and present urbanization processes like suburbanization, counterurbanization and reurbanization.
