The purpose of this study is to compare the competition and productivity of the US freight rail transportation industry for the past 41 years (1980 ∼ 2020), which consists of the two periods, before and after the abolishment of the Interstate Commerce Commission (ICC) in 1995.

This study investigates any relationships between the market concentration index values and labor productivity values in the separate two periods, and how the existence of a regulatory body in the freight transportation market impacted the productivity of the freight rail transportation industry by using a Cobb–Douglas production function on annual financial statement data from the US stock exchange market.

This study found that, after the abolishment of the ICC: (1) the rail industry became less competitive, (2) even if the rail industry had an increasing labor productivity trend, there was a strong negative correlation between the market concentration index and labor productivity and (3) the rail industry’s total factor productivity was decreased.

This study is to find empirical evidence of the effect of the ICC abolishment on the competition and productivity levels in the US freight rail transportation industry using a continuous data set of 41-year financial statements, which is unique compared to previous studies.

The purpose of this paper is to initially evaluate the most current and important complications of sustainable mega rail transportation projects. This purpose is assisted by thoroughly reviewing the foremost uncertainties and challenging issues of STI. Once these factors are established, they will be the base of STI indicators. Finally, to consolidate such alignment, the Sydney Metro and Melbourne Metro are then compared and analyzed. The analysis would then create a platform to measure sustainability and relevant complexities in mega rail transportation projects.

To further consolidate such hypothesis, this research investigated two mega rail transportation projects in Australia. Both Sydney Metro and Melbourne Metro Rail were selected as the basis of case study, as both possess similar sustainability aspects.

As an outcome this research found that, complexities in both of these projects were based on future challenges and opportunities including imperfect equalization or not balancing all the four sustainability indicators; and where and how to emphasize the overlapping of these four indicators. In summary, these findings can assist the relevant planners, to better prepare and manage mega railway infrastructure and their operations.

While the sustainability for transportation infrastructure has been covered extensively by other authors, this paper strengthens the four specific and separate STI indicators – especially for mega rail infrastructure. Although, there are some crossover areas within these indicators, however, this research separately validates each as an independent entity. Commonly, there are three dimensions within the sustainability domain – environmental, economical and social. Nevertheless, for this research, a fourth dimension engineering which includes all the technical focus, has been separately developed. This is particularly important to effectively deal with all the complexities, particularly for mega projects, such as rail transportation infrastructure. Accordingly, separating the engineering dimension would thus reshape the triple bottom line factors to include a separate technical focus. To further evaluate this separation of the four specific areas, two mega Australian rail transportation projects are then reviewed as experiments.

A transportation connectivity strategy is a crucial part of an adaptive, congruent and sustainable tourism transportation system and is of concern to countries focusing on growing their tourism economy. This study aims to gain a better understanding of the relationship between transportation connectivity and the tourism economy through a configuration analysis.

This study uses fuzzy-set qualitative comparative analysis on a sample of 153 cities in China to provide an understanding of the impacts of transportation connectivity strategies, with the co-effecting factors of socio-economic status, tourism resource endowment and hospitality capacity, on the development of regional tourism economies.

There are multiple paths that lead to regional tourism economic development (a high level of tourist arrivals or a high level of tourism revenue). High-speed rail can play a supportive role, while air travel or traditional rail remains central to the tourism economy. Socio-economic status (i.e. city size and city gross domestic product) and hospitality capacity are identified as crucial influencers for the development of the tourism economy.

This study confirms the validity of deploying configuration analysis (based on the equifinality theory) to establish the relationship between transportation and the tourism economy. The finding of more than one configuration led to a new consensus on how multiple factors influence the tourism economy.

Suggestions on transportation connectivity strategies for different regions are provided.

This study demonstrates the need to place greater emphasis on configurations that lead to tourism economy development instead of the effect of a single transportation mode.

摘要

交通连接策略, 作为打造具备适应性、一致性、可持续性的旅游交通系统的重要环节, 被重视旅游经济增长的国家密切关注。组态分析有助于更好地理解交通连接与旅游经济之间的关系。

本研究以中国的153个城市为样本, 使用模糊集定性比较分析方法（fsQCA）, 研究交通连接策略、社会经济水平、旅游资源禀赋、酒店接待能力等协同因素对区域旅游经济发展的影响。

有多种组态可以导致区域旅游经济的发展（表现为高水平的游客人数或高水平的旅游收入）。航空旅行或传统铁路仍然是影响旅游经济发展的核心条件, 而高铁可以发挥支持作用。社会经济水平(即城市规模和城市生产总值)和酒店接待能力被认为是影响旅游经济发展的关键因素。

本研究证实了应用组态分析（基于等效性理论）建立交通连接策略与旅游经济之间关系的有效性。不唯一的多组态的发现会推动关于多种因素如何影响旅游经济的新共识形成。

本研究针对不同地区提出交通连通策略的建议。

本研究表明, 比起考虑单一交通方式产生的影响, 探索旅游经济发展需要更加重视多种交通连接策略的配置。

Una estrategia de conectividad del transporte es una parte crucial de un sistema de transporte turístico adaptable, congruente y sostenible, y es de interés para los países que se centran en el crecimiento de su economía turística. Un análisis de la configuración puede ayudar a comprender mejor la relación entre la conectividad del transporte y la economía del turismo.

Este estudio utiliza el análisis comparativo cualitativo de conjuntos difusos (fsQCA) en una muestra de 153 ciudades de China para proporcionar una comprensión de los impactos de las estrategias de conectividad del transporte, con los factores coadyuvantes de la situación socioeconómica, la dotación de recursos turísticos y la capacidad de hospitalidad, en el desarrollo de las economías turísticas regionales.

Existen múltiples vías que conducen al desarrollo económico del turismo regional (un alto nivel de llegadas de turistas o un alto nivel de ingresos por turismo). El ferrocarril de alta velocidad puede desempeñar un papel de apoyo, mientras que el transporte aéreo o el ferrocarril tradicional siguen siendo fundamentales para la economía turística. El estatus socioeconómico (es decir, el tamaño de la ciudad y el PIB de la ciudad) y la capacidad de hospitalidad se identifican como factores de influencia cruciales para el desarrollo de la economía del turismo.

Este estudio confirma la validez de utilizar el análisis de configuración (basado en la teoría de la equifinalidad) para establecer la relación entre el transporte y la economía del turismo. El hallazgo de más de una configuración condujo a un nuevo consenso sobre cómo influyen los múltiples factores en la economía del turismo.

Se proporciona una tipología de estrategias de conectividad del transporte para diferentes regiones.

Este estudio demuestra la necesidad de poner mayor énfasis en las configuraciones que conducen al desarrollo de la economía turística en lugar del efecto de un único modo de transporte.

The purpose of this paper is to examine the long-term cointegrating relationship between ocean, rail, truck and air cargo freight rates, as well as the short-term dynamics between these four series. The authors also test the predictive ability of these freight rates on major economic indicators.

The authors employ a vector error-correction model using 16 years of monthly time series data on freight rate data in the ocean, truck, rail and air cargo sectors to examine the interrelationship between these series as well as their interrelationship with major economic indicators.

The authors find that truck freight rates and as well as dry bulk freight rates have the strongest predictive power over other transportation freight rates as well as for the four major economic indicators used in this study. The authors find that dry bulk freight rates lead other freight rates in the short-run but lag other freight rates in the long run.

While ocean freight rate time series have been examined in a large number of studies, little research has been done on the interrelationship between ocean freight rates and the freight rates of other modes of transportation. Through the use of data on five different freight rate series, the authors are able to assess which rates lead and which rates lag each other and thus assist future researchers and practitioners forecast freight rates. The authors are also one of the few studies to assess the predictive power of non-ocean freight rates on major economic indicators.

High-speed maglev technology can address the issues of adhesion, friction, vibration and high-speed current collection in traditional wheel-rail systems, making it an important direction for the future development of high-speed rail technology.

This paper elaborates on the demand and significance of developing high-speed maglev technology worldwide and examines the current status and technological maturity of several major high-speed maglev systems globally.

This paper summarizes the challenges in the development of high-speed maglev railways in China. Based on this analysis, it puts forward considerations for future research on high-speed maglev railways.

This paper describes the development status and technical maturity of several major high-speed maglev systems in the world for the first time, summarizes the existing problems in the development of China's high-speed maglev railway and on this basis, puts forward the thinking of the next research of China's high-speed maglev railway.

The purpose of this research paper is to understand the major factors considered before choosing the mode of transportation for the freight movement in India by different stakeholders and look into the future prospects on each of these sectors, i.e. railways, roadways and inland waterways.

This paper collected the primary data from the various stakeholders in the transportation sector and the secondary data through websites and various ministries of each of the sectors. The various factors are then determined by thoroughly analysing the responses by performing factor analysis in SPSS.

Earlier railways were the preferred medium of transportation, but the dynamics shifted during the 90’s to roadways, and now, it is responsible for nearly 60% of the freight traffic with waterways slowing increasing its share of the pie. Also, there are a lot of factors which stakeholders consider, but the major factors that came out are cost, sustainability, timing, government initiatives, visibility and performance.

The result of this study implies that sectors should create a robust network for easy reach of the customers and try working in conjunction to create an efficient, affordable and highly connected network. This study will also help in taking vital decisions regarding the future planning of transportation sector.

The findings help in improving the transportation network and help in better decision-making by various stakeholders while choosing the mode of transportation.

Given the current focus on sustainable development, there is a need to identify the current status of the transport sector in developing countries and the obstacles to the development of a sustainable transport system. Thus, the purpose of this paper is to provide a critical review on what needs to be done in such countries towards a sustainable transportation system. The focus of the paper will be on the South Asian context. In order to achieve the aim, the paper examines the current issues, the policy context and the key actions required in the countries selected in South Asia (i.e. Afghanistan, Pakistan, Sri Lanka, Bangladesh, Bhutan, Maldives and Nepal).

The main method used for the project was a combination of semi-structured interviews and focus groups. In addition, a policy analysis was also carried out with a use of secondary data. Altogether, 348 interviews and 16 focus groups (with 157 participants) were carried out in the selected six countries. Although the purpose of the research methods was to carry out a situational analysis of each country mentioned above on seven societal challenges identified under the EU’s Horizon 2020 research programme, this paper only focusses on presenting the findings relating to sustainable transport.

Findings reveal that South Asian countries need to improve different aspects of their transportation sector, starting from national-level transportation policies. Sustainable transportation is not merely about mobility but also about creating safer, convenient and environmentally friendly transportation systems. Some key actions needed for these include introducing driver and passenger safety regulations, establishing vehicle emissions test centres to reduce CO2 emissions, and introducing public-private partnerships where useful.

This study provides a robust policy direction towards the introduction/improvement of a sustainable transportation system in South Asian countries.

This paper analyzes two external costs often associated with port development, cost to fisheries from marine dredge disposal and damages from air pollution, using estimates of development and operation for a proposed (but since cancelled) container port as a case study. For dredge disposal, a bio-economic model was used to assess short- and long-term and indirect (joodweb) damages to fisheries from marine disposal of clean sediments. In the case of air pollution, estimates of annual activity levels and emission coefficients are used to estimate incremental annual emissions of three key pollutants (NOx, HC and CO) for trucks, trains, yard vehicles, and vessels. These estimates allow for phasing in of strict new air pollution regulations. For both external costs, sensitivity analyses are used to reflect uncertainty. Estimates of shadow values in year 2002 dollars amount from $0.094 per cubic yard to $0.169 per cubic yard of clean dredged material for the selected disposal site and from $0.0584 per mile (jor current control standards) to $ 0. 0023 per mile (after phasing in of new regulations) for air pollution from heavy trucks.

Railway freight transportation in Europe is in a state of change. The system has been freed from protection from the beginning of 2007 and market forces will start to act. Demand for, and the market share of, this form of transportation has been declining for decades. Therefore, there is a need to know more about the efficiency and productivity of this sector, in order to understand the nature and magnitude of potential restructuring changes. This paper aims to address this issue.

Data envelopment analysis (DEA) is used to analyze different European countries throughout the longitudinal observation period of 1980 to 2003. Also partial productivity analysis is used to support DEA evaluation.

Based on DEA results, it is found that those countries that were showing the highest efficiency levels in the 1980s, without exception, experienced an efficiency collapse in the 1990s. These include both former Eastern Bloc and West European countries. Based on partial productivity analysis, it is proposed that productivity of locomotives and railway tracks should be the primary target of productivity improvement in these formerly highly efficient countries. The efficiency analysis shows also that currently the most efficient railway freight transportation is located in the Baltic States, namely Estonia and Latvia. If one does not include data from Estonia and Latvia in the overall analysis, in a European context the only truly improving performance indicators are partial productivities of freight wagons, and staff.

In contrast to previous efficiency studies in this sector, railway freight transportation shows high differences between European countries; it is necessary to address further research in the efficiency and productivity area in this respect to identify ongoing structural change.

Restructuring in European railways is just taking its first steps, and a combination of downsizing and greater freight volumes is needed if this mode of transportation is going to prosper in the future, and take market share back from others. Restructuring within this sector will most probably result in increased internationalization, mergers and acquisitions, and intermodal transportation solutions. These all represent new avenues for research.

This article helps to advise clear remedies for European railways and suggests interesting avenues for further research.

The purpose of this paper is to develop a better understanding of the factors that influence a shipper's decision to choose air cargo as a mode of shipment.

A disaggregate multinomial discrete choice model is developed using freight shipment survey data to identify critical factors influencing air cargo mode choice. Disaggregate revealed preference data is obtained from surveying 347 manufacturers, freight forwarders, and other third-party service providers.

The empirical model developed in this research shows that the rate of shipment, time of transit, cost-per-pound shipped, quantity shipped, perishability and delay rate of the mode are significant factors that influence mode choice.

The discrete choice model developed can be improved by taking into account logistics costs not considered in this research. Perhaps more in-depth surveys of the shippers and freight forwarders are needed. Additionally, improving the mode choice model by including stated preference data and subsequently incorporating service quality latent variables would be beneficial.

Identifying the sensitivity of the shippers to various factors influencing mode selection enables transportation planners make better demand forecast for each mode of transportation.

This paper extends previous mode choice studies by analyzing mode selection between air cargo and other modes. Better forecasting is achieved by replacing the logit model with probit, heteroscedastic extreme value and mixed logit models.
