Long-run impacts of policy packages on mobility in Belgium
While generating many economic benefits, transport also causes many problems with congestion, accidents and environmental costs being the most relevant ones. These problems called for government intervention in order to achieve a more sustainable transport system. LIMOBEL aimed to help the government in its decision process, taking into account different objectives.
The aim of LIMOBEL was to develop a fully operational modelling tool to study the impact of transport policies on the economy and on emissions in order to help the government to make choices when it is faced with different objectives.
LIMOBEL builds upon existing models, extending these models and linking them together.
The first model is the PLANET developed at the Federal Planning Bureau (FPB), a medium-term and long-term projection model for freight and passenger transport demand in Belgium.
The second model is NODUS, a multimodal freight network model developed at Group Transport & Mobility (GTM).
The third model is the environmental impact assessment model developed at VITO (Vlaamse Instelling voor Technologisch Onderzoek) to determine the emissions of various air pollutants and greenhouse gases by different vehicle types and to calculate the social costs of these emissions using the impact pathway methodology.
A first result of the project was the identification of the main links between the different model components.
Secondly, it was possible to determine the basic set-up of the long-term economic model.
Thirdly, work was undertaken to obtain an updated and more realistic network model.
The result is a better insight in the components of the generalised costs for passenger and freight transport, the introduction of the line concept for rail transport and an update of the network. Finally, the methodology for the environmental impact assessment model was developed further.
The end product of LIMOBEL consisted in:
- (i) a fully operational modelling tool and
- (ii) a set of cost-benefit analyses of alternative policy packages.
