Résumé :

The reasons for choosing or promoting a certain way of transporting goods are dependent on a

multitude of factors. Shippers will be interested in reliable logistics and low cost, while

authorities are in general more concerned with relieving congestion and minimizing the

environmental impact of transport in general.

Historically, transport analysts have mainly focused on either economic or environmental

aspects, but have hardly ever joined the two. This thesis aims to achieve an integrated

approach to the assessment of transport, in this case focused on intermodal chains at a micro

level. This means we focus on the performance of the entire intermodal logistic chain – as a

whole – and not on the performance of each transport mode.

During the three last years, we have participated in the European funded 6th framework

project CREATING, where we have been the leader of the work package in charge of the

assessment activities.

To achieve this task, we developed an integrated assessment framework that can translate

quantitative and qualitative values into a single performance indicator.

This model is implemented in usable software, quite easily understandable by the users.

The impacts considered in the integrated assessment framework are related to various

performance areas: the economy, the environment, the logistics and the safety.

The logistics and the safety are directly taken in charge by the software while the economy

and the environment require the use of an underlying model developed by colleagues from

Delft University, working in close relation with the model developed within this thesis:

LODA stating for Logistic Optimization and Decision Aiding. The ‘Delft’ model provides

outputs related to the costs and the environmental impacts of transport chains based on

technical aspects of transport means. These outputs are directly imported in LODA to perform

the integrated evaluation.

A list of indicators is elaborated for each performance domain. After a first aggregation step,

the model provides four global indexes presenting the performance of transport projects

related to the four above-mentioned fields. These four aggregations are realized by means of a

multicriteria decision aiding method named PROMETHEE stating for Preference Ranking

Organization Method for Enrichment and Evaluation and other aggregation methods such as a

sum and an average.

Then, a final indicator provides the global performance of transport projects by aggregating

the indexes into one global score by using the PROMETHEE method. This single indicator

makes possible to rank the scenarios on the basis of the aggregated performances.

In addition, it is possible to test the robustness of the ranking on the basis of different weights.

The assessment framework developed in this thesis is demonstrated by means of cases under

evaluation in the CREATING project.

The first case covers the transport of cargo from Germany to South-Eastern Europe by road

and by intermodal scenarios featuring RORO (stating for Roll-on / Roll-off) waterborne

transport along the Danube. This case highlights the major benefits of an intermodal transport

compared to an ‘all-road’ transport regarding the pollution, the reduction of accidents as well

as the positive impacts on the costs and the logistics.


The second case revolves around the transport of biomass on a lake in the Paijanne area in

Finland. The woodchips are used as an important source of energy by a local power plant

which plans to increase its activity in the coming years. The increase demand of biomass will

generate a lot of traffic which can not be absorbed by the only road transport. So, regarding

the lake system, the waterborne transport alternative could be an efficient solution to ensure

the sustainable development of biomass transport in that area.

The third case is dedicated to the study of conditioned banana transport (temperature

controlled and kept under an atmosphere with reduced amounts of oxygen). The bananas

arrive in Antwerp, from South America, by seagoing reefer ships and have to be transported

to ripening houses in Strasbourg. This transport is currently realized by truck. The impacts of

intermodal transport alternatives are studied and show that intermodal transport can perform

better than an ‘all-road’ transport.

Finally, the integrated assessment framework is applied to the transport of chemicals over the

inland waterways in the Netherlands. This transport is currently done by single hulled ships

which need to be replaced by double hulled ships in the near future while the transport by

road could take a slight shortcut. Once again, the model demonstrates the competitiveness of

inland navigation.

The above-mentioned cases highlight the possible application of our model in real conditions

while possible further developments can be identified regarding the internalization of external

transport impacts. On the basis of the case studies, it appears that intermodal transport

represents a pertinent alternative to ‘all-road’ transport allowing a better ‘modal balancing’.
