大型陆地口岸交通组织设计研究

口岸是国家对外贸易往来的门户和通道,当前陆地口岸已从贸易通商通道升级为集商业、办公、休闲娱乐为一体的复合区域。以港珠澳大桥珠海口岸交通组织设计为例,分析大型陆地口岸交通特性,并对口岸动态交通组织、静态交通设施进行初步探讨和研究,从而为大型陆地口岸的综合交通组织设计提供理论指导。     

Smart River发展现状与思考

针对Smart River 2011会议,介绍了Smart River在内河电子航道图、RIS系统及其应用,以及其他有关Smart River的最新发展情况,同时介绍了我国长江电子航道图、信息服务,及其他内容的发展近况。通过对比分析,认为我国在下一步内河航运发展中,应全面统筹发展。在着力电子航道图的全面发展,加强内河航运信息服务的同时,大力发展公铁水联运。同时要注意保证船员适任性,灾难应急的处置。环境的保护、规划选址方法也应该得到充分的重视。     

内河船舶交通流建模与仿真研究

为了更精确地模拟内河船舶交通流的运行状态,根据内河船舶相互影响特性,将航道作为交通流中为船舶提供通航服务的主要资源,将船舶行为及相互之间的耦合关系模型化,在此基础上构建基于通航服务资源的内河船舶交通流模型.利用仿真软件进行仿真实验,结合长江干线某断面流量数据进行实例验证.实验结果表明,该模型能较好地模拟内河宏观交通流.     

Maritime logistics as an emerging discipline

The evolution of maritime logistics as an emerging discipline has resulted, to a large extent, from the increasing and varied demands of shippers and customers and the rapidly changing role of ports in the context of supply and logistics chains. Scholars are becoming increasingly aware of the need to integrate logistics and supply chain management concepts in the maritime transportation chain and operations. This article aims to provide a review and foundation for understanding the domain of maritime logistics and to assess its potential as an emerging discipline. To do so, a framework for understanding the various aspects of maritime logistics strategy and implementation is developed. A synthesis of the existing knowledge on maritime logistics is done by integrating diverse explorations forming the basis of this framework. We draw upon the literature on maritime transport and ports and primarily theliterature that analyses concepts by adopting an economic or management perspective.     

Advances in port studies: the contribution of 40 years Maritime Policy & Management

Port economics, management and policy have progressively emerged as a distinctive research field, and a core part of maritime economics. This paper provides an analysis of all the 267 port studies published in Maritime Policy & Management (MPM) since its inception in 1973. This paper provides a content analysis for seven interrelated research theme categories including main research topics and methods, authorship distribution and citation counts. It is demonstrated that MPM played, and continues to play, a key role in publishing research on seaports. The published research increasingly applies established analytical frameworks to ports. The paper concludes with a discussion on current challenges for port-related research.     

Overseas trade vis-a-vis overseas shipping: Growth and performance in India (1999–2009)

Maritime trade has been and even continues to account for about a lion's share of India's total cargo volumes. Despite the growth of multimodal transport (by land, water and air), shipping still continues to be the major mode of transport in the bulk carriage of country's overseas trade. In view of this vital role of shipping, in the first four decades of independence, under the initiative of planned development and active government support, India's shipping and port sector saw dramatic growth in their performance to build adequate national fleet, in keeping up with the transport of overseas cargo. However, the onset of economic liberalization in 1991 has given rise to many new dimensions in the development of the shipping and port sector of the country with a significant redefinition of shipping and port services, in response to the new global trend patterns. For instance, it has also established the new era of containerization in the mode of cargo delivery from the dominance of the era of bulk and break-bulk trade during the decade of sixties and seventies. Moreover, as global competition increases, in response to this emerging trade patterns within this country, India's volume of traffic growth also increases manifold. So, India's shipping and port sectors need, significantly, to build up and furnish their capacity by increasing the frequency of this mode of transport i.e. the growth of the national overseas fleet to meet this surging demand. This paper, therefore, have focused on this role of shipping in such rising overseas trade, with a view to examine the shipping performance (the growth of overseas fleet) in response to the growing overseas trade at all ports of India during the period (1999–2000 to 2008–2009), in terms of both a mathematical model and a graphical representation. Finally, it concludes that the absolute overseas trade, being highly import dependent, have led to a more or less stagnant performance in overseas shipping, owing to the lack of the adequate growth of absolute overseas exports during this period.     

Identifying Governance Relationships Between Intermodal Terminals and Logistics Platforms

Abstract

Governance theory examines different ways of managing resources and relationships in order to achieve a desired outcome. This paper applies governance theory to intermodal terminals and logistics platforms, extending previous work on ownership to include different operational models. An inductive methodology is used to derive a typology of governance relationships from an analysis of the transport and logistics literature. The classification developed in this paper explores different kinds of integration that can help support growth of intermodal transport services. The understanding of transport governance is extended via three key relationships: first, between the logistics platform and the site tenants (therefore, encouraging consolidation and efficiencies that can boost rail services at the site); second, between the terminal operator and rail service provision (which can aid service planning and train loading factors); and third, between the inland site (either terminal, logistics platform or both) and port(s), (thus enabling better planning and efficiency of port rail shuttles).

内河航道横流对船舶航行的影响

为了使船舶能安全通过航道内的横流区域,利用水槽进行遥控自航船模试验,提出了内河航道横流对船舶航行横漂速度、漂角、航迹带宽度和漂距影响的经验公式,分析了Ⅳ与Ⅴ级航道横向流速的限值范围。分析结果表明:横流对船舶航行的影响程度主要与对岸航速成反比,与横流的大小及区域长度成正比,与船型大小(航道等级)成反比,同时与驾驶员的航行经验和初始船位有关;在限制航路航行方式过程中,Ⅳ与Ⅴ级航道对岸航速为2、3、4m·s-1时,可克服的一个船长内横流限值为0.48、0.58、0.70m·s-1。     

BIM技术在内河航道设计中的应用

鉴于BIM技术在航道建设中的优势,将Autodesk系列BIM软件引入内河航道的设计工作中,利用Civil 3D、Subassembly Composer(部件编辑器)、Infraworks设计软件实现内河航道疏浚工程和护岸工程的参数化设计和可视化展示,并进行横断面定制、标签定制、模板文件定制等二次开发,提出适用于内河航道工程三维正向设计和可视化演示的技术方法。
