Decoupling road freight transport from economic growth has been acknowledged by the European Union as a key means to improving sustainability. It is therefore important to identify both the coupling and decoupling drivers of road freight transport demand in order to determine possible factors that may contribute to reduce road transport in the future without curbing economic development. This research proposes an Input–Output (IO) structural decomposition analysis (SDA) to explain road freight transport in terms of a set of key factors that have strongly influenced road freight demand in recent decades in European countries—such as economic growth, economic structure and the evolution of road transport intensity (including improvements in both supply and transport systems). This methodological approach allows us to quantify and compare their contribution in different European countries to either increase or decrease road freight transport demand. The empirical basis for this analysis is a dataset of nine European countries which have IO tables and road transport data available from 2000 to 2007, comprising data on domestic production, imports and exports as well as tonne-kms for 11 types of commodity classes. The results show that, as a whole, aggregate road transport demand has grown—driven mainly by economic activity—but this growth has been strongly curbed in some countries by changes in road freight transport intensity and moderately by the dematerialization of the economy. International transport has been also proven to be a key factor driving road freight transport volumes. Moreover, the increased penetration of foreign operators in national haulage markets appears to have reinforced the final decoupling levels observed in some cases.  相似文献

Abstract

Between 1997 and 2004, gross domestic product increased in real terms in the UK by one‐fifth, while the volume of road freight movement remained stable. This suggests that the long‐awaited decoupling of economic and freight transport growth has begun, possibly leading to a new era of sustainable logistics. This paper reviews previous research on the decoupling issue and recent trends in gross domestic product/freight tonne‐km elasticities in Europe and the USA. It then examines 12 possible causes of the observed decoupling in the UK using published statistics from a wide range of British and European sources. This analysis indicates that around two‐thirds of the decoupling is due to three factors whose impact can be quantified: the increased penetration of the British road haulage market by foreign operators, a decline in road transport’s share of the freight market, and real increases in road freight rates. Several other factors, most notably the relative growth of the service sector, the diminishing rate of centralization, and the off‐shoring of manufacturing, appear to be having a significant effect, though this finding cannot be measured on the basis of available statistics. The paper concludes that, while the decoupling is in the right direction from a public policy standpoint, the net environmental benefits are likely to be quite modest.  相似文献

China’s transport industry is energy intensive and high-polluting. While with the surging urbanization and the development of service industry, China’s economic relies more and more on the transport sector. Therefore, exploring the relationship between transport energy-related carbon emission (TECE) and economic development is crucial to the realization of China’s “Post Paris” mitigation target. The paper carries out a decoupling research between TECE and Gross domestic product (GDP) at both national level and province level based on Logarithmic Mean Divisia Index (LMDI) decomposition analysis with the extended Kaya identity and Tapio decoupling model. The model quantifies eight factors’ effects on the relationship with focusing on external macro socio-economic related factors (i.e., spatial pattern, urbanization, per capita service industry output value, reciprocal of the service industry’s share of GDP, and demographic variable) successfully. The key conclusions are indicated as follows: (1) the national decoupling status was extensive coupling during 2004–2010 and then weak decoupling during 2010–2016. The progress can be attributed to the decline of energy intensity. (2) Per capita service output was always the prominent factor to promote carbon emissions growth in different time periods and provinces with inhibiting the advancement of decoupling process, followed by urbanization. (3) Scenario analysis shows that with the continuous growth of traffic demand and the promotion of urbanization, improving energy efficiency has become the key link to realize the decoupling between China’s TECE and its economy.  相似文献

In recent years, Chinese railway freight transport has been facing great challenges from transport market reformation and economic expansion. Although the total volume of railway freight has been increasing, its market share has decreased greatly, especially at the beginning of migration from command economy to market economy. This paper considers four aspects believed to be responsible for the loss of the railway freight market share. First, we review the history and current situation of the Chinese railway freight transport and study the relationship between economic development and freight transport in China. Second, the causes resulting in the loss of the market share of railway freight are analysed in detail. Third, the current measures taken by Chinese Railways (CR) to restore its competitiveness are discussed. The effects of these measures on railway traffic volume, market share and productivity are also studied. Finally, the way forward for the future of CR is discussed. It is concluded that CR has not yet adapted sufficiently to new economic conditions, although in recent years progress has been made. Further reform will be needed.  相似文献

The logistics industry plays a critical role in boosting China’s economic development, although at significant externality costs. Using the 1980–2010 data, we examine the historical evolution of energy consumption in China’s logistics industry. The logarithmic mean Divisia index (LMDI) method was used to analyze the key factors that drove the chronicle changes in logistics energy consumption in China. Changes in energy consumption of China’s logistics industry are attributed to growth in logistics activity, modal shift in freight transportation, increases in transport intensity, and overall improvements in energy intensity: (1) China’s logistics industry enjoyed fast growth with an average annual growth rate of 9.65% from 1980 to 2010. Increase in logistics activity has been the major force driving up logistics energy consumption (accounting for 48.8% of logistics energy increase); (2) Logistics energy consumption increased by 22.91 times, averaging at 11.9% growth per year. Fuel consumption in highway transportation has become more dominant in logistics energy consumption; (3) While changes in logistics activities, transportation modes and transport intensity pushed up logistics energy consumptions, improvements in energy intensity helped significantly to curb the energy rise in China’s logistics industry.  相似文献

Before the introduction of terminal handling charges (THCs), traditional freight rates included both ocean freight charges and terminal charges at ports. Since the introduction of THCs in 1991, the freight rate has become a “port-to-port” charge that covers only the sea leg, while the on-shore costs of using the container terminals are charged separately as THCs. Although both THCs and freight rates are collectively set by conferences, in this study we argue that the former are easier to enforce because they are invariant to other attributes such as haulage distance, inland transport services and types of commodity being shipped. This argument is consistent with the empirical findings from this study that suggest the separation of ocean freight rates from terminal charges has increased the overall shipping charges. In addition, we find that THCs affect the Hong Kong container handling industry by lowering its throughput.  相似文献

This paper investigates intermodal freight transport planning problems among deep-sea terminals and inland terminals in hinterland haulage for a horizontally fully integrated intermodal freight transport operator at the tactical container flow level. An intermodal freight transport network (IFTN) model is first developed to capture the key characteristics of intermodal freight transport such as the modality change phenomena at intermodal terminals, physical capacity constraints of the network, time-dependent transport times on freeways, and time schedules for trains and barges. After that, the intermodal freight transport planning problem is formulated as an optimal intermodal container flow control problem from a system and control perspective with the use of the proposed IFTN model. To deal with the dynamic transport demands and dynamic traffic conditions in the IFTN, a receding horizon intermodal container flow control (RIFC) approach is proposed to control and to reassign intermodal container flows in a receding horizon way. This container flow control approach involves solving linear programming problems and is suited for transport planning on large-sized networks. Both an all-or-nothing approach and the proposed RIFC approach are evaluated through simulation studies. Simulation results show the potential of the proposed RIFC approach.  相似文献

Abstract

The paper discusses Tanzania's transport problems in the context of the prevailing acute economic crisis. It looks at the development of the transport system, especially the rail and road network, from the German days to the new Chinese‐built Tanzania‐Zambia Railway. The East‐West orientation of the major parallel rail lines and roads reflects the dependency of the economy on export‐import trade. A major challenge to the transport system is the haulage of agricultural products, mainly for export but also for the internal market, not to mention the haulage of imported commodities.

The provision and utilization of transport services is discussed in the context of the historical, and institutional setting of the road haulage industry, particularly its public and private sector configurations. Due to scarcity of foreign exchange, both sectors, especially the private, are starved of vehicles and spare parts.

The operation of ocean and lake shipping services and Air Tanzania are discussed. It is recommended that the latter should concentrate on essential domestic services plus some limited regional services. External financing of transport projects and its implications are also considered.

It is concluded that despite the break‐up of the East African transport system, the Tanzanian transport system, although shaky, has avoided major breakdowns and in some cases, especially in trade, has provided the foundation for at least medium‐term improvements. More attention is recommended to organizational problems of track use by freight and passenger carriers and to making the best use of existing facilities.  相似文献

This paper deals with two interrelated questions, namely the optimum size of a vehicle or vessel, and the structure of transport costs with respect to haulage distance. The relationship between these two questions has not been coherently dealt with previously in the literature, and the heuristic attempts at doing so have lead to both theoretical and empirical anomalies. This paper adopts an inventory optimisation approach in order to show that both of these questions can be treated in a unified manner and this allows us to show, first, that under very general conditions the optimum size of a ship increases with the haulage distance and haulage weight, and second, that the observed structure of transport costs with respect to the haulage distance and quantity is itself a result of this optimisation problem.  相似文献

In this paper long run structural relationship for freight transport demand is derived for railways in India using annual time series data for 1960–1995. Some of the recent developments in multivariate dynamic econometric time series modelling have been employed such as estimation of long-run structural cointegrating relationship, short-run dynamics and measurement of the effects of shocks and their persistence during the evolution of dynamic freight transport demand system. The models are estimated using a cointegrating vector autoregressive (VAR) modelling framework, which allows for endogeneity of regressors. Results indicate high GDP elasticity and low price elasticity, with real freight rate, i.e. the price variable behaving exogenously with respect to the system. Any disequilibrium in the short-run is likely to be corrected in the long run via adjustments in freight transport demand and GDP. Further, the demand system seems to be stable in the long run and converges to equilibrium in a period of around 3 years after a typical system-wide shock.  相似文献

In the next few years, exciting developments in the field of freight transport are likely to occur. The Channel Tunnel will be perceived as giving railways much greater distance of operation, compared to the current train ferry to/from Great Britain. The further development of swap-body technology will allow easier modal transfer and the creation, in 1992, of a single market in Europe will transform the pattern of trade. All of these are likely to have significant impacts on modal choice, and hence modal split, in freight transport. Reappraisal by many firms of the modes of transport used is likely but will it result in a net transfer of freight from road to rail and, if so, to what extent? To answer such questions, an accurate and reliable method of predicting modal split is required. Research in the past has concentrated on the development of modal split models based on generalised costs. These fail to explain adequately the prevalence of road freight in the UK. From surveys of freight managers within industry, it is clear that models to date rely too heavily on the economic cost factor and too little on behavioural factors (Jeffs 1985). This paper derives from a recent study of freight transport modal choice from the standpoint of the transport decision-maker within the firm. It attempts to shed light on the actual parameters which should be incorporated into a modal split model. Many variables appear to exert an influence on modal choice decision-making process. However, it is possible to categorise them into six main groups, namely: customer-requirements; product-characteristics; company structure/organisation; government interventions; available transport facilities; and perceptions of the decision-maker him/herself. It is the interactions and inter-relationships between these which ultimately determine freight modal split. This study has shown that the relationship between the outcome of the transport decision process and the values of particular determinants of modal split is not straight-forward, due to the complexity and variety of interactions involved. Perhaps one of the main reasons for researchers' failure hitherto to develop a successful modal-split model has been the preoccupation with techniques that rely on the development of common metric (e.g. generalised cost), which has led to the exclusion of some important explanatory variables along quite different dimensions. Another important issue concerns the appropriate level of aggregation. In order not to reduce the explanatory power of the key variables, it is important to work at a disaggregate level, although this does make substantial demands on data. The use of factor analysis enables both the aggregation of information without loss of behavioural reality and the specification of variables in terms of a common metric. In conclusion, freight transport has usually been examined within too narrow a framework. It must be placed firmly within the context of the total industrial process. The demand for freight transport is directly influenced by the level, composition and geographical distribution of production and consumption activities. Freight flows are complex and so it is highly unlikely that a universal mode-choice model can ever be developed. Future research should, therefore, be directed towards developing partial models in response to specific needs of those involved in decision-taking in the freight sector.  相似文献

In the process of rapid development and urbanization in Beijing, identifying the potential factors of carbon emissions in the transportation sector is an important prerequisite to controlling carbon emissions. Based on the expanded Kaya identity, we built a multivariate generalized Fisher index (GFI) decomposition model to measure the influence of the energy structure, energy intensity, output value of per unit traffic turnover, transportation intensity, economic growth and population size on carbon emissions from 1995 to 2012 in the transportation sector of Beijing. Compared to most methods used in previous studies, the GFI model possesses the advantage of eliminating decomposition residuals, which enables it to display better decomposition characteristics (Ang et al., 2004). The results show: (i) The primary positive drivers of carbon emissions in the transportation sector include the economic growth, energy intensity and population size. The cumulative contribution of economic growth to transportation carbon emissions reaches 334.5%. (ii) The negative drivers are the transportation intensity and energy structure, while the transportation intensity is the main factor that restrains transportation carbon emissions. The energy structure displays a certain inhibition effect, but its inhibition is not obvious. (iii) The contribution rate of the output value of per unit traffic turnover on transportation carbon emissions appears as a flat “M”. To suppress the growth of carbon emissions in transportation further, the government of Beijing should take the measures of promoting the development of new energy vehicles, limiting private vehicles’ increase and promoting public transportation, evacuating non-core functions of Beijing and continuingly controlling population size.  相似文献

This paper explores the long-run impacts of gross domestic product, exchange rate, and transport costs on bilateral air and ocean freight flows between the US and China. The study employs a cointegration framework by using export and import data over the period of 2003:Q1-2014:Q2. Results show that gross domestic product is the key determinant of bilateral freight flows, indicating that real income of a trading partner is a driving force of the bilateral freight flows between the US and China. In examining the sensitivities of the bilateral trade flows, air freight flows are found to be more responsive to a real income change than ocean freight flows. The bilateral exchange rate is a significant factor affecting the freight flows from China to the US, suggesting that a US dollar appreciation against the Chinese yuan increases the inflows of Chinese commodities to the US. The impacts of the bilateral exchange rate and transport cost are found to vary at industry and commodity levels. These findings support the importance of employing disaggregate data in the bilateral freight flow analysis.  相似文献

Over the last couple of decades there has been a trend in Western Europe and North America towards making the railway industry more able to compete successfully with road for freight haulage through deregulation and/or structural change. This trend has been drive, partly, by a concern to produce more commercially viable railway industries, but also by concerns to reduce the environmental impacts of road haulage through modal shift. The latter in particular has led to the development of public policies supportive of rail freight, particularly at the national or international levels. This paper reports on qualitative research that analysed public policy aimed at promoting rail freight in Britain but, unusually, the focus was on local rather than national policy. The research was an investigation of the approach of local authorities to the encouragement of rail freight as evidenced through their Local Transport Plans. The paper concludes that in Britain there has been a significant amount of local policymaking for rail freight and that although national policy matters are of overriding importance, the role of local policy is significant and can be developed further.  相似文献

The main line of the State Railway of Thailand to serve the Northeastern region of the Kingdom was built in 1900 to the town of Korat and subsequently extended to its northern extremity at the Laos border. The Friendship Highway, a modern highway parallel to the railway and serving the same transportation corridor, was completed in 1958 as far as Korat. In 1965 the northern extension of the Friendship Highway was opened to Nong Khai, the northern terminus of the railway.The effect of the nearby and parallel highway on freight traffic - for upland crops, vegetables, rice, kenaf, and forest products - is shown in terms of tonnages dispatched by the railway and in relation to the production of those commodities. Passenger traffic originating on the Northeastern railway line is analysed. Statistics indicating the shift in modal split between road and rail, for both freight and passengers in the Kingdom, are presented for a six-year period. An estimate of the loss in revenue for the Korat-Nong Khai segment of the railway has been made for both originating passengers and certain classes of freight traffic. Clearly demonstrated is the unceasing trend toward road haulage of freight and the use of highway buses by intercity passengers. This paper is intended to draw attention to the magnitude of the problem rather than to suggest definitive solutions.  相似文献

Improving the knowledge of demand evolution over time is a key aspect in the evaluation of transport policies and in forecasting future investment needs. It becomes even more critical for the case of toll roads, which in recent decades has become an increasingly common device to fund road projects. However, literature regarding demand elasticity estimates in toll roads is sparse and leaves some important aspects to be analyzed in greater detail. In particular, previous research on traffic analysis does not often disaggregate heavy vehicle demand from the total volume, so that the specific behavioral patterns of this traffic segment are not taken into account. Furthermore, GDP is the main socioeconomic variable most commonly chosen to explain road freight traffic growth over time. This paper seeks to determine the variables that better explain the evolution of heavy vehicle demand in toll roads over time. To that end, we present a dynamic panel data methodology aimed at identifying the key socioeconomic variables that explain the behavior of road freight traffic throughout the years. The results show that, despite the usual practice, GDP may not constitute a suitable explanatory variable for heavy vehicle demand. Rather, considering only the GDP of those sectors with a high impact on transport demand, such as construction or industry, leads to more consistent results. The methodology is applied to Spanish toll roads for the 1990–2011 period. This is an interesting case in the international context, as road freight demand has experienced an even greater reduction in Spain than elsewhere, since the beginning of the economic crisis in 2008.  相似文献

Abstract

Under the ongoing influence of globalisation, supply chains have changed significantly. New logistics and manufacturing systems have emerged, causing longer transport distances and increasing transport emissions. The existing research into the sustainability impacts of freight transport has largely viewed it as being a macro-level economic and political phenomenon and has ignored the interdependencies amongst micro-level economic actors, including firms and businesses in the private sector. In this paper, we presume that the lack of conceptualisation of freight transport in relation to wider institutional contexts and firm behaviour results in the lack of a holistic approach to understanding freight governance in the face of globalisation. We argue for the use of institutional economic geography lenses to elucidate the distribution networks of emerging logistics and manufacturing practices and its implications for freight transport. We illustrate our argument through a broad look at the European logistics and manufacturing practices and global production.  相似文献

In 1994/95, the Australian rail freight task was approximately 100 billion tonne kilometres (btkm). This freight task included some 37 btkm for the haulage of iron ore in Western Australia, 28 btkm for coal haulage in Queensland and New South Wales and about 16 btkm for interstate rail freight. This paper mainly concerns how improvements can be made to the efficiency and competitiveness of interstate rail freight services through the upgrading of sections of mainline track that currently have severe speed‐weight restrictions. Recent improvements in rail freight efficiency are discussed, with emphasis on two indicators: average unit revenues (cents per net tonne km), and average energy efficiency (net tonne km per MJ). Rail freight efficiency is high for the Western Australia iron‐ore operations, Queensland coal operations and Adelaide‐Perth general freight operations. However, between Australia's three largest cities of Melbourne, Sydney and Brisbane, some 36% of the mainline track fails to meet basic fast freight train standards with a ruling grade of 1 in 66 and no curve radius less than 800 m. The contraints on efficient rail freight operations imposed by severe terrain, and how the effects of terrain may be reduced by improved track alignment, are discussed. Some economically warranted rail track investment measures are outlined, including those identified for a National Transport Planning Taskforce. These measures have the potential to reduce liquid fuel use by over 250 million litres a year. Factors affecting competitive neutrality between road and rail freight that are outside of the present scope of Australia's National Competition Policy are broadly considered. These factors include the extensive upgrading of the National Highway System with full Federal funding, and low levels of road cost recovery from heavy trucks operating over long distances.  相似文献

Abstract

A phenomenon new to the Polish situation—the deregulation of rail transport—is presented. Despite its primarily legal nature, deregulation also implies various economic, socio‐political and spatial consequences. The relatively short period over which partial deregulation of public transport in Poland has been in effect (i.e. since 2000) ensures that the issue has not been taken up by Polish geographers as a research field. However, it has been of interest to Polish economists. Deregulation is a phenomenon of primary importance, with direct implications for the character, quality, type, intensity and spatial differentiation of transport (including freight and passenger traffic) within the market economy. This paper, therefore, presents the impact of the recent changes in the legal system (as regards deregulation) on the current pattern of railway connections of the major carriers. As the majority of these originate beyond the Polskie Koleje Państwowe (Polish State Railways) Group, they can be said to be independent of the main former state carrier.  相似文献

The circular and functional economies are being presented in the literature as potential strategies for future sustainable societies. In terms of the consequences for supply chains, they will promote a much more dispersed and diversified, local and network based usage of goods than the current economy, which is comparatively linear, concentrated, long distance oriented and scale economy based. A gap in the literature is the assessment of the effects of these systems on freight transport flows. In our paper, we present a first attempt at estimating this impact using freight transport scenario building and quantitative modelling. In order to translate the main parameters that characterize these systems into factors determining freight transportation volumes, we develop a framework based on a typology of goods categories describing functional and spatial proximity between producers and consumers. In order to simulate changes in the economy, we develop scenarios for the shifting of goods from one category to another and, additionally, include internalization policies that should guide their realization. We calculate the impacts on freight flows using a new interregional transport model for France that includes distribution chains and produces estimates of external costs of transport. Our results show that circular and functional economies could lead to a 2–5% reduction of air pollutant emissions and up to a 14–26% reduction if combined with the internalization of external costs. The scenario with ongoing mass production for differentiated demand is found to lead to a 5% increase of environmental impacts compared to the baseline.  相似文献
