The dry port concept: connecting container seaports with the hinterland

The dry port concept is based on a seaport directly connected by rail with inland intermodal terminals where containers can be dealt with in the same way as if they were in a seaport. The main purpose of the article is to extend the theory behind the dry port concept and to define three dry port categories; distant, midrange and close. The findings show that the dry port concept can help identify ways of shifting freight volumes from road to more energy efficient traffic modes that are less harmful to the environment, relieve seaport cities from some congestion and facilitate improved logistics solutions for shippers in the port’s hinterland.     

The spatial characteristics of inland transport hubs: evidences from Southern India

This paper investigates the spatial characteristics of inland transport hubs with evidence from the users’ choice of dry ports in cargo exportation in Southern India. The findings indicate that the current solution, where shippers often choose dry ports located closest to their production base, is not the optimal solution in terms of the minimisation of transport cost, mainly due to government policies and dry port’s inability in providing value-added services to shippers. This study provides important insight on the major attributes in explaining the spatial characteristics of inland transport hubs, especially in developing countries.     

Service charge and capacity selection of an inland river port with location-dependent shipping cost and service congestion

The inland waterway transportation has attracted a lot of attention worldwide in the last fifteen years. This paper studies the location, service charge and capacity decision of an inland river port to maximize its revenue or profit. The cargo shippers are assumed to be uniformly distributed along the inland river and can be shipped to the junction port via pure road transportation service or transshipment service with the inland river port. The natural heterogeneity of the river’ navigational condition is modeled by a location-dependent waterway transportation cost and the service congestion on the port is captured by the M/M/1 queueing model. We analytically investigate the properties of the optimal solutions for various decision problems associated with the inland river port. The effects of the natural heterogeneity and port service congestion of those optimal solutions are investigated. Those theoretical results are carefully examined in the case study of the Yangtze River.     

The directional development of intermodal freight corridors in relation to inland terminals

This paper examines the spatial development of freight infrastructure, developing a conceptual model that draws attention to the directional development of intermodal corridors in relation to inland terminals. Two concepts of vertical control of the development process are proposed in this paper, beginning with Inside-Out, whereby inland intermodal terminals seek greater integration with their sea ports, often driven by public body intervention. By contrast, Outside-In development is displayed by the conscious use of an inland node as a tool for sea port actors (whether port authorities or terminal operators) to expand their hinterland and capture discretionary cargo.One of the key distinctions between the two models is the role played by different government approaches to the development of inland terminal facilities. Therefore three national examples are discussed: Sweden, where the public sector is directly involved in development; Scotland, where the private sector is left to develop terminals but government encourages the process through spatial planning and modal shift funding; and the USA, where the national government has traditionally taken little action.The primary contribution of this paper is the research agenda developed out of the conceptual model above, which should be applied to additional case studies in future work. Arising from the conceptual model and the examination of the role of public bodies is a debate on the role of regulation. However the subject of regulation is only touched upon in this paper, therefore more research is required on the government’s role in infrastructure planning and regulation in order to determine the best approach in this policy area.     

Delimiting port hinterlands based on intermodal network flows: Model and algorithm

This study aims to propose a tangible approach to delimiting the probabilistic hinterland of a port of interest. We first build a geometric model for the probabilistic port hinterland based on intermodal network flows jointly using discrete choice analysis and geographical information of shippers. We further design an algorithm that can efficiently determine the hinterland boundaries using the sample approximation of shippers’ choice probabilities. We provide theoretical results that characterize the minimum computational effort required to achieve a certain degree of accuracy in the sample approximation. We also offer two numerical case studies to justify the proposed approach.     

Hinterland operations of sea ports do matter: Dry port usage effects on transportation costs and CO2 emissions

Decreasing carbon dioxide (CO₂) emissions is one of the most important tasks for the society in the 21st century. One possibility to decrease emissions originating from transportation is to utilize more rails instead of relying simply on road transportation. In the dry port concept an inland intermodal terminal is connected to a sea port using railways. This study analyzes impacts of dry ports in a Finnish context. We compare two different configurations: In the first one shippers drive directly to a sea port, while in the second one they use dry ports. The systems are evaluated by using discrete-event simulation. In the systems we are interested in two issues: (1) Level of CO₂ emissions, and (2) Costs to transport the goods in different configurations. We use different scenarios for future energy prices and estimate both the costs and CO₂ emission development in these scenarios. We also compare the results to a situation, where emissions are minimized instead of costs. Implications on larger scale are also discussed, for example in the Baltic Sea and North Sea area, where strict sulfur emission restrictions are seen to harm sea transport and increase concentration on small number of sea ports.     

Choosing a port: An analysis of containerized imports into the US

Using a unique data set of individual shipments, port characteristics, and actual freight charges, we examined potential factors within management controls that affect the attractiveness of a port for containerized shipments. We hypothesized that the importance placed on each factor varies by the size of the shipper. We find support for our hypotheses that large shippers emphasize the factors affecting speed of delivery more than the freight charges compared to small shippers. These findings have managerial implications because investments in port development would pay off depending on the fit between the type of investment and the customers’ needs.     

Governing inland ports: a multi-dimensional approach to addressing inland port–city challenges in European transport corridors

Inland ports have been put forward as crucial linkages for efficient global freight transport and corridor development. However, the present understanding of inland ports appears to be limited to network-based views with a maritime port focus (Outside-In), in which inland ports play second fiddle. We argue that inland ports as independent structures (Inside-Out) deserve equal consideration and that in addition to the transport dimension, the spatial, economic and institutional dimensions of inland ports are vital and should not be neglected. The goal of this paper is to apply the concept of port–city challenges to inland ports. The results of an institutional analysis of Dutch case study evidence show that challenges facing inland ports and cities take many forms but that all share a commonality in the trade-offs between positive and negative externalities. We observe different governance strategies in coping with these trade-offs and find that a proactive stance towards zoning contributes to efficiently accommodating mutually exclusive dimensions of inland port development.     

Shipping route choice across geographies: Coastal vs. landlocked countries

This paper investigates how geography and transportation costs influence the decisions by shippers of which port of export to use. Using a large sample of disaggregated shipments originating from several countries in Europe, we show that European logistics networks exhibit a low level of international integration that affects shipping route choice. Furthermore, we find significant differences in shipping behaviors across landlocked and coastal countries, with shippers in landlocked countries avoiding long land transportation, crossing borders readily, and placing more value on transportation infrastructure. These findings have implications in designing port competitiveness strategies and economic development policies in landlocked countries.     

Development of seaport–dry port dyads: two cases from Northern Europe

An increase in sea freight flows generates an almost proportional increase in inland freight flows, and what takes place inland will influence the ability of intermodal transport systems to further accommodate the growth of international trade. This could be facilitated by dry ports, which have been developed to support seaport operations as well as the overall operations of intermodal transport systems.The aim of this paper is to develop the Wilmsmeier et al. (2011) framework of directional development by taking into account development over time. The purpose is to contribute to the understanding of the development of seaport–dry port dyads by the analysis of two in-depth case studies from Northern Europe. A qualitative research strategy is applied to increase understanding of the development. The results contribute to earlier studies of spatial development of seaport–dry port development by taking into account development over time and by increasing the understanding of the actors, the types of dry ports and the services influencing the development of the dyads.     

Recent maritime research projects on the Lower Loire area

This paper deals with the problems of access to an estuary port, the security of navigation and services such as towage provided for shipping. The port triptych is also considered — the port itself, its foreland and hinterland — showing to what extent the port can be seen as a fundamental feature of the regional economy.     

Stable vessel-cargo matching in dry bulk shipping market with price game mechanism

This paper proposes a model of stable vessel-cargo matching with price game mechanism in the dry bulk shipping market. The research aims at mimicking the bid of disadvantaged participants in the process of matching preferred objects. The matching equilibrium and price equilibrium are formulated between the shippers and carriers. A price game mechanism based Gale-Shapley algorithm is developed. Three scenarios of market dominated by shippers, market dominated by carriers, and equilibrium market are discussed in computational experiments. It is showed that if disadvantaged participants bid with the price game mechanism, they may gain more surpluses even in the negative position.     

Integration of inland waterway transport in the intermodal supply chain: a taxonomy of research challenges

This paper identifies research opportunities which will enable the further integration of inland waterway transport in the intermodal supply chain. Intermodal transport may be interpreted as a chain of actors who supply a transport service. Inland navigation can play a crucial role in increasing supply chain service performance. A first group of research challenges lies in the evolving relationship between transport geography and logistics activities. The next set of research challenges has the objective to encourage efficient operations in IWT: development of a system wide model for IWT, integration of operational planning systems and analysis of bundling networks. A third group of research efforts is directed towards shippers and consignees who use the intermodal transport chain to send or receive their goods: further development of models that integrate intermodal transport decisions with supply chain decisions and creation of green supply chains. A fourth cluster of research challenges concerns the problem domain of external cost calculations. Finally detailed time series data on freight transport should be collected to support these future research tracks.     

Attributes driving the selection of trucking services and the quantification of the shipper’s willingness to pay

This paper investigates the selection of trucking services by shippers that require the movement of truck shipments. A set of pragmatic attributes are postulated to describe trucking services. They are used in a stated choice experiment that collects data and preferences from shippers. A mixed logit model is estimated in order to test the attributes and quantifying the shipper willingness to pay for them. The results are used to provide meaningful negotiation guidance for truck-related shippers and carriers, a significant contribution to literature in transportation, logistics, and supply chain management. A numerical example illustrates the use of the model.     

Analyzing private communities on Internet-based collaborative transportation networks

The establishment of private communities on Internet-based transportation networks is a relatively new trend that has met with mixed success. Within industry, there has been uncertainty over the costs and benefits of these communities to shippers and carriers. Through a theoretical model based on assumptions derived from industry executives, this paper suggests that shippers may indeed benefit by establishing private communities. Further, the results show that in high-trust relationships carriers may be no worse off by cooperating with shippers in their private communities.     

The development of the Yangtze River container port system

This paper sheds an empirical light on port development patterns by discussing the structure and the development of the Yangtze River ports system. We argue that the Yangtze River system is going through a regionalization phase, mainly in relation to the port of Shanghai. This process started on the lower Yangtze but is now also moving upstream. The transition towards the port regionalization phase is typically a gradual and market-driven process that mirrors the increased focus of market players on logistics integration. This paper builds on the existing literature on port systems and adapts port development models to river ports. Furthermore, we employ some statistical techniques that are common to the analysis of port systems, and introduce some techniques that have not been used much by transport geographers in ports. This paper will address the dynamics in the Yangtze River ports system by analyzing the level of cargo concentration and the degree of inequality in operations of the container ports. The paper also assesses observed differences in development of ports in different areas along the river (upstream/downstream) and reflects on the role of ownership structures in shaping regional load centre networks.     

Network analysis of container barge transport in the port of Antwerp by means of simulation

Inland navigation plays an important role in the hinterland access of the port of Antwerp. In this paper alternative bundling strategies for container barge transport in the port of Antwerp are analyzed. Four alternative hub scenarios are simulated and compared with the current situation with respect to the operational characteristics of the network. Discrete event simulation is used to analyze the impact on waiting times and capacity utilization at potential hubs and at sea terminals. The hub scenarios under investigation are the organization of an intermodal barge hub on the right river bank, an intermodal hub on the left river bank, a first multihub scenario with a local collection/distribution network and a potentially improved multihub scenario taking into account the specific structure of the port of Antwerp. The second multihub scenario offers most opportunities for reducing the turnaround time of all inland terminals. All hub scenarios lead to important efficiency improvements in the handling of barges at sea terminals.     

Port system evolution – the case of Latin America and the Caribbean

The explosion of global container trade in the last two decades has significantly influenced the port geography of Latin America & the Caribbean (LAC), leading to a concentration of container traffic at selected ports. Theory suggests that, as port systems become mature, they tend to deconcentration, partly due to the emergence of secondary ports. Previous research has examined the region’s dominant ports, but an unanswered research question is how the evolution of this port system is influencing and being influenced by the actions of those ports currently occupying a secondary rank in the LAC port hierarchy.The methodology is based primarily on analysis of time series data on container movements between 1997 and 2012, revealing patterns of cargo flows and transhipment location choices. The institutional context of devolution processes and new investments in the region provides additional insight into the performance of selected ports. From a theoretical perspective, this analysis is situated within the context of recent institutional approaches that examine the port’s ability to act through critical moments and junctures, in order to deepen understanding of which of the various factors influencing port system deconcentration are the most sensitive to successful institutional adaptations.Results show that the manufacturing of strategic locations can be successful and may have driven the emergence of secondary ports in the LAC system. This finding demonstrates how path dependence can be challenged by new developments, the identification and success of which are nevertheless contingent on factors such as the first mover advantage, port planning regimes and diversification of port roles. The paper identifies some of the key factors influencing the transition of a port system from concentration at a few dominant ports to a deconcentrated system of primary and secondary ports, which can be applied to other port systems in future research.     

Planning for competitive port expansion on the U.S. Eastern Seaboard: the case of the Savannah Harbor Expansion Project

With the expansion of the Panama Canal, port cities along the U.S. Eastern Seaboard are competing to attract the increased trade expected once the project is complete in 2015. Competition includes extensive investment in projects for port expansion, dredging, and multimodal transportation for greater hinterland connectivity, fueled in part by uncoordinated federal port investments without a larger strategic vision for national port and trade infrastructure. One of the competing ports is in Savannah, Georgia, which is the country’s fourth busiest container port. Savannah is about to embark on a $652 million project that will dredge thirty-two miles of the Savannah River from 42 to 47 feet to attract and accommodate Post-Panamax container ships. The paper analyzes the geographic coastal impacts of port competition, and looks at the unique circumstances of the Greater Savannah Metropolitan Region in planning for future growth of its port. The case illustrates the geographic tensions of uncoordinated maritime freight and logistics planning with fragile coastal and riparian ecologies. The dramatic interventions in port excavation also demonstrate how global forces of technological change and port expansions in other parts of the world are reshaping local geographies.     

Container Ocean-transportation System Design with the factors of demand fluctuation and choice inertia of shippers

This paper introduces an optimization model (COSDM) for a Container Ocean-transportation System with the objective of maximizing the revenue of a liner company while taking into account the seasonal fluctuation in transportation demand and the choice inertia of shippers. The COSDM optimizes shipping network design and fleet deployment simultaneously, and it optimizes plans for changing the shipping network and for distributing slots in ships based on the fluctuation in demand and the characteristics of the shippers’ choice inertia. To solve COSDM, a heuristic algorithm is created that combines Genetic Algorithm and Simplex Method. The results show that the COSDM gives an optimized design scheme of the system that takes into account the stability of transportation services and improves the user experience of shippers while increasing the revenue of the liner company. Moreover, the results also reveal new explanations for the increasing size of container ships.
