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。

Effects of the ‘Belt and Road’ initiative on the wine import logistics of China

China’s Belt and Road (BR) initiative is expected to facilitate international trade between the countries involved. In this study, we review the special requirements of wine logistics and the market growth potential of wine consumption in China. A model minimizing generalized logistical costs is developed and applied to wine imports in China, so that the best candidate cities in which to locate transport gateways and distribution centers can be identified. Our analysis suggests that the most preferred gateways are Shanghai, Tianjin, Guangzhou, and Hong Kong, which all have similar delivery costs. In comparison, Beijing and Chongqing have much higher delivery costs, mainly because they do not have good access to marine transport and/or efficient domestic distribution networks. For long-distance intercontinental transport of large volumes of wine, marine shipping remains the only viable delivery mode. However, wine distribution within China extensively uses air, road, and water transport. Therefore, cities with excellent multi-modal transport services are better positioned to become wine logistics gateways. Our study also highlights the importance of value-added services and good government support, which are important factors that influence distribution costs and quality.     

基于语义挖掘的快递运输货品风险评价研究

为提高快递运输的风险监测管控能力，降低因快递货品风险导致城市安全事件发生的可 能性，本文基于语义挖掘方法将快递运输货品描述转化为风险的量化表征，为快递运输风险评价 提供可量化的客观指标依据。基于网络大数据资源提供的法院判决书数据，将物品词条与判决 结果相关联，通过隐狄利克雷分布模型挖掘物品风险主题，结合模糊均值聚类方法，实现对快递 货品语义风险的量化表征与柔性划分。与传统方法中依赖检视人员查验既定违禁品清单后的主 观判断方法不同，本文充分挖掘网络文本数据中的可迁移知识，并应用于种类繁多的快递运输货 品，有效避免人工评价造成的漏检、错检情况。研究结果表明，本文方法具有较高的准确率与较 低的误报率，获得的风险评价值不再是0或1的是非判断，有利于开展多样化、针对性的风险预警 及应对措施。     

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.
