East Coast vs. West Coast: The impact of the Panama Canal’s expansion on the routing of Asian imports into the United States

Asian firms shipping to inland US points choose between West and East Coast ports. West Coast shipments often have lower transit times but higher freight charges. To investigate factors affecting this routing decision, a coast choice model is estimated. Results are then used to project shifts in demand with the coming completion of the Panama Canal expansion. Our simulations show that if the Panama Canal expansion generates significant transit time savings on shipments from Asia, as projected, that there will be major shifts in traffic from West to East Coast ports, raising important policy implications for port operators on both coasts.     

The Air Liberalisation Index as a tool in measuring the impact of South Africa's aviation policy in Africa on air passenger traffic flows

In Africa, the Yamoussoukro Decision (YD) to date remains the single most important air transport reform policy, the continent-wide implementation of which remains pending. This study employs the Air Liberalisation Index (ALI), developed by the Word Trade Organisation (WTO) Secretariat, to measure the impact of each of the seven quantifiable market access features of South Africa's aviation policy in Africa on air passenger traffic flows. A fixed one-way panel regression technique was applied to panel data, representing five air transport markets: intra-African, the SADC, East African, West African and North African over two time periods (2000–2010; 2006–2010). The results proved to be significant in three markets, intra-African, the SADC and East African and provide new insights into the relationship between air passenger traffic flows and aviation policy in the South African – intra-African and regional contexts.     

Dynamics of liner shipping network and port connectivity in supply chain systems: analysis on East Asia

The study of ports in supply chain systems is an emerging area of importance which has drawn more attention from researchers in recent years. This paper presents a new perspective in this research area by examining the calling patterns of container shipping services in order to understand the dynamics of port connectivity and inter-port relationships in the supply chains. Empirical evidence is drawn from four major ports in East Asia, namely Shanghai, Busan, Kaohsiung and Ningbo. The study identifies the shipping capacity, trade routes and geographical regions connected to the ports, shipping lines involved, and the extensity and intensity of inter-port relationships among the four container ports from liner shipping network’s perspective. The findings show that most of the shipping capacity employed on the major east–west trade routes became non-exclusive and involved calls at two or more of the four ports. Port planners, terminal operators and carriers could capitalise on opportunities through exploitation of complementary relationships that exist among the selected ports, such as offering a package for shipping lines to call at a portfolio of terminals owned by the same terminal operator. Policy and research implications as well as recommendations are discussed for various stakeholders concerned with port planning and regional development.     

Changing travel to work patterns in South East England

The Greater South East England region of the UK constitutes a “global mega-city region”. The UK Government’s 2003 Sustainable Communities strategy proposes major new growth centres in South East England at Ashford, Milton Keynes, Stansted, Cambridge and Thames Gateway. These, along with the upgrade of the West Coast Main Line in 2004 and the completion of the Channel Tunnel Rail Link in 2007, could have major impacts on commuting patterns. To understand the effect of these changes on commute distance and mode choice, the relationships between travel-to-work patterns and socio-economic and land-use characteristics are examined. The analysis suggests that the creation of the new growth centres may result in increased car use but is unlikely to result in longer journeys to work.     

Intermodal containerized shipping in foreign trade and regional accessibility advantages

Intermodalism has become one of the most significant transformations of freight transportation in the United States over the past two decades. The coupling of shipping modes has enabled shippers to more fully realize the respective time and costs advantages of respective modes. The opportunity to take advantage of intermodalism when shipping manufactured goods overseas may provide an essential competitive edge to a company or to an entire region engaged in world commerce. The change in the freight accessibility map of the United States to foreign markets that can be ascribed to intermodal infrastructures and operations has so far not been studied. With the help of a geographic information system, this paper analyzes this transformation in the United States by mapping integral place accessibility measures of five-digit zip code areas with respect to gateways for export of manufactured goods, especially containerized freight. The performance of the intermodal freight network is evaluated by comparing accessibility measures based on the highway network and on the intermodal network, respectively, for all North American container ports, as well as for subgroups of container ports on the Eastern Seaboard, the Western Seaboard, and the Gulf Coast of North America. The paper discusses regional winners and losers in the new national freight transportation system.

Global intermodal liner shipping network design

This paper presents a holistic analysis for the network design problem of the intermodal liner shipping system. Existing methods for liner shipping network design mainly deal with port-to-port demand. However, most of the demand has inland origins and/or destinations. Thus, it is necessary to cope with inland origin–destination (OD) pairs involving a change in transport mode from inland transportation to maritime shipping. A method is first proposed to convert inland OD demand to port-to-port demand. Then, a framework for global intermodal liner shipping network design is proposed. Finally, the proposed methodology is applied to and numerically verified by a large-scale network example.     

Sailing speed optimization for container ships in a liner shipping network

This paper first calibrates the bunker consumption - sailing speed relation for container ships using historical operating data from a global liner shipping company. It proceeds to investigate the optimal sailing speed of container ships on each leg of each ship route in a liner shipping network while considering transshipment and container routing. This problem is formulated as a mixed-integer nonlinear programming model. In view of the convexity, non-negativity, and univariate properties of the bunker consumption function, an efficient outer-approximation method is proposed to obtain an ε-optimal solution with a predetermined optimality tolerance level ε. The proposed model and algorithm is applied to a real case study for a global liner shipping company.     

Levels of internationalization in the container shipping industry: an assessment of the port networks of the large container shipping companies

This paper examines the internationalization level of the world’s largest container shipping companies by examining their port networks. The results of our analysis show that only three of the nineteen companies could be considered as being truly ‘International’ and service the ‘lion’s share’ of the major and minor ports distributed across the globe. The port networks of the other companies in our survey, whilst having individualized features, shared common characteristics. Guided by the ‘Uppsala Model of Incremental Internationalization’ (Johanson and Vahlne, 1977), we were able to identify four internationalization levels of a container shipping company that are indicated by their port network.We argue that the port network plays an additional role as it contributes to the internationalization level of the container shipping companies. This is important because the internationalization level affects the container shipping company’s ability to expand its customer base both at a local and international level. Local customers would have access to a larger international destination network and international customers would be able access a larger local distribution network without transhipping between different companies.Amongst other issues, we were able to determine that, for the analyzed container shipping companies, ‘Internationalization’ of a port network means including or excluding ports in specific regions or sub-regions in their own network, and that a company’s home base or history plays a significant role in this development.     

Analysing passenger network changes: The case of Hong Kong

Passenger throughput at Hong Kong International Airport (HKIA) has shown steady growth since its opening. Various aspects relating to HKIA have been studied in prior literature. This paper investigated changes in HKIA's passenger network for the period of 2001–2012 and used the gravity model to examine the key factors explaining its passenger traffic flows. The findings suggested that HKIA's passenger network has changed significantly and expanded to many new different destinations. Two regions (East Asia and Southeast Asia) were the most important markets for HKIA, and most key destinations connected by Hong Kong showed healthy growth. Nine factors could explain passenger traffic flows between Hong Kong and its key destinations: Hong Kong GDP per capita, GDP per capita of destinations connected by HKIA, distance, airport hub status of the destination airport, tourist destinations connected by HKIA, numbers of passenger airlines in service, bilateral trade flows, speaking a common language and having strong cultural/colonial links with Hong Kong, and the route presence of Cathay Pacific.     

A successful upriver port? Container shipping in Montreal

This paper revisits the advantages and disadvantages associated with the location of Montreal in the container shipping market. Traditionally, the St. Lawrence River has proved a competitive way to connect the industrial heart of North America with Europe. How does this premise hold in an era of ever-larger containerships? Recent trends in container market share, the number of ships deployed and the services provided are analyzed. It is found that while Montreal continues to maintain its rank among top container ports on the East Coast of North America, the competitive environment has changed significantly over the last 5 years.     

Introduction to the special issue: Air transport in the Global South

Research on the development and impacts of air transport has hitherto focused mainly on developed countries in the Global North, and relatively little on less developed countries in the Global South. The seven papers of this Special Issue of the Journal of Transport Geography aim to address this imbalance and encourage further research on air transport development in the Global South. In recent years, the Global South has witnessed significant changes in air transport networks and policies, with implications for economic growth, spatial development and airline business models. This Special Issue explores some challenges to air transport development in the Global South for countries in Africa, South America, the Middle East and Asia, including links between air transport and economic development, the evolution and key drivers of air transport growth and the spatial distribution of passenger airline networks, and the development and impact of low-cost carriers. It also identifies opportunities for future research in this growing area.     

Polar super seaways? Maritime transport in the Arctic: an analysis of shipowners’ intentions

The seasonal melting of sea ice in the Arctic Ocean, which has been confirmed for several summers in a row and is widely documented, has become a hot topic in the media. It is fuelling many speculative scenarios about the purported renewal of a “cold war”, or even an actual armed conflict, in the Arctic, for the control of both its natural resources and its sea routes.The melting sea ice is indeed giving a second wind to projects, abandoned in the 19th century, to find shorter sea routes between Europe and Asia. A look at the map shows the savings in distance that can be achieved with the Arctic routes: for example, a trip between London and Yokohama through the Northwest Passage is 15,700 km and 13,841 km through the Northeast Passage, which is significantly shorter than the route through Suez (21,200 km) or Panama (23,300 km).² These findings fuel the idea that these Arctic routes, because they are shorter, are bound to attract abundant through traffic, and consequently will become a major political issue. Amid the media widespread image of a future maritime highway across Arctic seas, even some scientists yield to the popular image and assert, without proof, that Arctic traffic is set to increase rapidly.³ Beyond the seemingly decisive advantage of Arctic routes, however, there remain many obstacles to navigation (Lasserre, 2010d). In addition, these scenarios for the development of marine traffic in the Arctic remain highly speculative and are not based on an analysis of shipowners’ perceptions, which is the goal of this paper.This article will thus present the results of an empirical survey conducted among shipping companies to determine their interest in developing activities in the Arctic. Besides examining the potential development of shipping in Arctic routes, this research must be replaced in the context of intense competition between shippers, competition that makes both service reliability and costs of transport paramount. In this competition structure, the benefits of established routes between major hubs seems to prevail, so that new routes have difficulty being established.     

Liner ship fleet deployment with container transshipment operations

This paper proposes a liner ship fleet deployment (LSFD) problem with container transshipment operations. The proposed problem is formulated as a mixed-integer linear programming model which allows container transshipment operations at any port, any number of times, without explicitly defining the container transshipment variables. Experiments on the Asia-Europe-Oceania shipping network of a global liner shipping company show that more than one third (17-22 ports) of the total of 46 ports have transshipment throughputs. Computational studies based on randomly generated large-scale shipping networks demonstrate that the proposed model can be solved efficiently by CPLEX.     

The effect of high fuel costs on liner service configuration in container shipping

For shipping activities, not least container shipping, bunker fuel is a considerable expense. In the last 5 years, bunker prices have risen considerably. An increasing bunker price in container shipping, especially in the short term, is only partially compensated through surcharges and will therefore affect earnings negatively. This paper deals with the impact of increasing bunker costs on the design of liner services on the Europe–Far East trade. The paper assesses how shipping lines have adapted their liner service schedules (in terms of commercial speed, number of vessels deployed per loop, etc.) to deal with increased bunker costs. The paper also includes a cost model to simulate the impact of bunker cost changes on the operational costs of liner services. The cost model demonstrates for a typical North Europe–East Asia loop that the current bunker prices have a significant impact on the costs per TEU even when using large post-panamax vessels. The model also shows shipping lines are reacting quite late to higher bunker costs. The reasons that explain the late adaptation of liner services relate to inertia, transit time concerns, increasing costs associated with fixing schedule integrity problems and fleet management issues.     

From colonization to national territories in continental West Africa: the historical geography of a transport infrastructure network

This paper argues that in order to study the geohistory of a transport infrastructure network it is necessary to identify the link between networks and territorial scales during a given period. It focuses on the creation of road and rail networks in French West Africa during the colonial period and in the land-locked States during the national period, which involves post-independence development policies. The network is perceived in this paper as the manifestation of the political will to facilitate traffic within a delimited space. Within the colonial and then the national periods roads and railways were thus constructed as part of a process that can be interpreted as the outcome of a compromise between a territorial project and the capacity to implement it. This geohistorical study thus allows us to identify, with reference to the link between borders and networks, the successive geographical linkages (railway and port combinations with their subsequent branches, national roads, economic roads, external connections) which have been applied in the delimited spaces in question. This exercise has concentrated particularly on continental West Africa.     

Is spatial dispersal the dominant trend in air transport development? A global analysis for 2006–2015

The economic performance of a city or region is considered to be intertwined with its air travel capability. It is thus important for planners and stakeholders to understand the changes in the global aviation network. This study investigates the global aviation network, taking 10 years worth's OAG data from the years 2006–2015 and examines whether a spatial dispersal trend dominates the development of the aviation industry. It considers the aviation network at the airport level, and the airport–city level, which may consist of one or more airports. After clarification of the various definitions of concentration, we find that there appears a trend toward a dispersal pattern in the global aviation network at the airport level. On the other hand, there appears a slight concentration at the airport–city level. Besides, there have been some major capacity expansions at airports in the Middle East and East Asia, while the capacities of some traditional hubs in Europe and North America have become increasingly constrained since the 2008 global financial crisis. Furthermore, our study provides further observations consistent with the phenomenon of bypassing of traditional hubs, especially mega-hubs. Competition for passengers among hubs and secondary airports, especially in multi-airport cities, is discussed.     

A mobilities approach to tourism from emerging world regions

Increasing numbers of people from the emerging world regions, Asia, Latin America, Africa and the Middle East engage in tourism practices at domestic, intra-regional and long-haul international scales. In this article, we deploy an innovative application of the mobilities approach, which we argue moves beyond the Eurocentrism implicit in modernist tourism studies, in a comparative analysis of tourism in and from these regions and those in the ‘West’. Our analysis opens up the systematic study of tourism in emerging world regions in terms of the mobilities paradigm, and concludes: one, travel had a multiplicity of origins in societies in the emerging regions, but most did not possess an equivalent emic term to ‘tourism'. Two, tourism at domestic and intra-regional levels tends to be entangled with other discretionary mobilities, whereas the long-haul level is more differentiated. Three, the development of domestic discretionary travel in emerging regions can be represented by four overlapping ‘mobility constellations’. Four, there are significant historical differences between the regions in their long-haul mobility constellations, although their kinetic hierarchies are all still steep. Five, forms of movement and associated practices of discretionary travellers from the emerging regions and Western countries became increasingly similar under the impact of socio-technological, economic and cultural globalisation. Six, differences between the emerging regions, particularly Asia, and the West are most salient on the emic level of representations of international travel: the specific cultural motive forces for tourism do not centre on authenticity-seeking, but are instead bound up with prestige and markers of modernity.     

Oriental imagery and American attitudes toward Asia: an exploratory tourism study

The concept of Orientalism has served to define post-colonial thinking, reflecting the West's interpretation of non-Western individuals and cultures. In this binary set, the West/us is approached as representing the standard, while the East/them represents that which is outside the norm. For the last few decades, Orientalism has continued to influence discussions in tourism studies; nevertheless, there is a dearth of empirical studies examining how the discourse lives out in daily tourism practices. Therefore, employing quantitative research methods, this study explores what Orientalism means to contemporary Americans and how it affects their attitudes toward Asian destinations. The result indicates that the imaginary construct of the East has reflected three different dimensions, namely contempt, curiosity, and fear, through which the Western world has traditionally framed the non-Western world; however, Americans generally believe that contemporary Asia cannot be adequately explained in these traditional and fixed ways. This study suggests that two terms, Asia and the East, connote very different meanings in contemporary American society, revealing how the traditional discourse of Orientalism is transformed and reinterpreted, although not totally changed, within the changing nature of the contemporary global environment.     

Tourism and climate change: a review of threats and adaptation strategies for Africa

The intersection of tourism and climate change has seen significant research over the past two decades, focusing particularly on issues of mitigation and adaptation in the global North. Research output has predominantly been centred on the Mediterranean and Nordic countries and number of localities in North America. The global South has seen significantly less investigation, despite having significantly lower adaptive capacity to the impacts of climate change, and numerous countries with rapidly growing tourism sectors. The African continent specifically has seen appreciably less research than other countries in the global South, despite arguably having the lowest adaptive capacity and projections of severe impacts of climate change to the tourism sector from temperature increases, changes in precipitation volume and sea level rise. This paper therefore presents a review of the existing literature on adaptation strategies of tourism sectors and participants in African countries. The crucial argument of this paper is in highlighting the need for an increase in research into the threats of climate change to tourism in African countries, identifying future research trajectories. The development of such knowledge would assist in the development of adaptation and mitigation strategies for these most vulnerable tourism economies.
