Intermodal Terminal Subsystem Technology Selection Using Integrated Fuzzy MCDM Model
Intermodal transportation is the use of multiple modes of transportation, which can lead to
greater sustainability by reducing environmental impact and traffic congestion and increasing the
efficiency of supply chains. One of the preconditions for efficient intermodal transport is the efficient
intermodal terminal (IT). ITs allow for the smooth and efficient handling of cargo, thus reducing the
time, cost, and environmental impact of transportation. Adequate selection of subsystem technologies
can significantly improve the efficiency and productivity of an IT, ultimately leading to cost savings
for businesses and a more efficient and sustainable transportation system. Accordingly, this paper
aims to establish a framework for the evaluation and selection of appropriate technologies for IT
subsystems. To solve the defined problem, an innovative hybrid multi-criteria decision making
(MCDM) model, which combines the fuzzy factor relationship (FFARE) and the fuzzy combinative
distance-based assessment (FCODAS) methods, is developed in this paper. The FFARE method
is used for obtaining criteria weights, while the FCODAS method is used for evaluation and a
final ranking of the alternatives. The established framework and the model are tested on a real-life
case study, evaluating and selecting the handling technology for a planned IT. The study defines
12 potential variants of handling equipment based on their techno-operational characteristics and
evaluates them using 16 criteria. The results indicate that the best handling technology variant is
the one that uses a rail-mounted gantry crane for trans-shipment and a reach stacker for horizontal
transport and storage. The results also point to the conclusion that instead of choosing equipment
for each process separately, it is important to think about the combination of different handling
technologies that can work together to complete a series of handling cycle processes. The main
contributions of this paper are the development of a new hybrid model and the establishment of
a framework for the selection of appropriate IT subsystem technologies along with a set of unique
criteria for their evaluation and selection
How to monitor sustainable mobility in cities? Literature review in the frame of creating a set of sustainable mobility indicators
The role of sustainable mobility and its impact on society and the environment is evident and recognized worldwide. Nevertheless, although there is a growing number of measures and projects that deal with sustainable mobility issues, it is not so easy to compare their results and, so far, there is no globally applicable set of tools and indicators that ensure holistic evaluation and facilitate replicability of the best practices. In this paper, based on the extensive literature review, we give a systematic overview of relevant and scientifically sound indicators that cover different aspects of sustainable mobility that are applicable in different social and economic contexts around the world. Overall, 22 sustainable mobility indicators have been selected and an overview of the applied measures described across the literature review has been presented
Challenges and barriers for a sustainable transport system – exploring the potential to enact change
This report is divided into three parts; the first part summarizes the results from a workshopconducted within the TRANSFORuMproject. The second part presents the results of interviewscarried out with different experts discussing the different goals and their perceptionsof what might prevent or delay appropriate implementation. The third part is based on a literature reviewdiscussing how to overcome or remove the various barriersand challenges. The overall aim ofthe studies presented in this report is to identify barriers but also to present necessary steps which need to be takenin order to help achieving the goals.The term "Barrier" relates to something which prevents some form of progress or movement, while "Challenge" can be something difficult but also something which is regarded as stimulating; or an opportunity
