Freight Transport Decarbonization: A Systematic Literature Review of System Dynamics Models (original) (raw)
2015
CONTEXT South Africa's latest Greenhouse Gas Inventory indicates that in 2010 the transport sector contributed a total of 47.4 Mt CO2e in direct greenhouse gas (GHG) emissions, or 8.4% of the country's total emissions. Freight transport is thought to account for about half of the emissions from the combustion of fossil fuels. It is widely recognised that the shift from road to rail is one of the biggest opportunities for reducing GHG emissions from the freight transport sector. Along with improved and alternative vehicle technologies and fuels, it is included as a mitigation option in government's Mitigation Potential Analysis. The road to- rail shift forms part of the Department of Transport's strategic goal to deliver an efficient and integrated infrastructure network, and will in part be facilitated by government's rail re-capitalisation programme. However, a shift from road to rail is not without its challenges. It is important to also understand the degree t...

Sustainability-based review of urban freight models
Soft Computing, 2019
This paper provides a review of models and decision support systems for urban freight transport (UFT). The originality of this study is that the analysis framework has been developed to outline the progress on UFT specifically related to the sustainability issue. Accordingly, contributions regarding UFT and addressing at least one factor of sustainability have been analysed by cross-referencing categories of models with impacts on sustainability. Results from this work are supposed to help enhance research concerning operations research (OR) for sustainable UFT by pointing out gaps that need to be closed and opportunities for future research. There is also an attempt to understand what is stopping researchers from including selected sustainability factors in the optimisation models. This paper also finally proposes some developments, not only in the OR field, that are preparatory for elaborating new models or improving the existing ones.
Freight Modal Policies Toward a Sustainable Society
Scientia Iranica, 2019
Freight transport policy analysts struggle to shift truck freight movements to rail to diminish transportation externalities including environmental costs and safety issues. Therefore, policy-makers need to be aware of the consequences of their decisions beforehand. This study is mainly focused on two policies targeting fuel price and access to rail transportation. A nationwide freight mode choice model is developed for Iran, and shippers' tendency to choose rail or truck freight transportation is analyzed by considering the shipping time and cost, commodity weight, commodity type, and rail accessibility. Total fuel consumption and air pollution costs are compared in various scenarios. Based on the results, environmental transportation costs are significantly reduced as a result of the modal shift from truck to rail freight transportation, if the government reallocates the gasoline subsidy to the construction of prioritized railroads.
The Impact of Urban Freight Transport: A Definition of Sustainability from an Actor's Perspective
Transportation Planning and Technology, 2008
This paper presents a definition of sustainable urban freight transport (SUFT), based on the existing theories and concepts, and develops an indicator set that describes SUFT. The definition of SUFT makes a categorisation of actions possible which enables actors to select effective strategies towards SUFT. The indicator set consists of two levels: impact indicators Á which describe how the urban freight transport violates the principles of sustainability; and performance indicators Á which describe different categories determining the characteristics and performance of the urban transport system. A literature study analyses the characteristics determining the performance of actors in the urban freight transport chain. Knowing the current state and improvement potential of the urban freight transport system are prerequisites for defining successful strategies and implementing effective actions.
SUSTAINABLE FREIGHT TRANSPORT (REVIEW OF MARIME TRANSPORT 2012)
The importance of freight transport as a trade enabler, engine of growth and a driver of social development is widely recognized. However, the associated adverse impacts of freight transport activity on the environment, human health and climate are also cause for concern. Overall, transport consumes over 50 per cent of global liquid fossil fuels and is projected to grow by 1.4 per cent per year from 2008 to 2035 and to account for 82 per cent of the total projected increment in liquid fuel use. It is also estimated that freight in tons per kilometre will triple by 2050 and that energy demand of commercial transportation -trucks, aeroplanes, ships and trains -will rise by over 70 per cent by 2040, driven by economic growth particularly in developing countries. At the same time, the transport sector accounts for around 13 per cent of all world greenhouse gases (GHGs), of which 5.5 per cent are related to logistics (with freight transport accounting for 90 per cent of the total share). Nearly 25 per cent of global carbon dioxide (CO2) emissions are transport related and these are expected to increase by 57 per cent worldwide (or 1.7
