The ISHTAR Project (FP5 – EESD Programme) aim was to build an innovative
decision support tool for advanced urban management through the integrated
analysis of the various environmental effects of technical and non technical
The suite includes both existing and newly developed models, covering the
areas of citizens’ behaviour, transport, vehicle safety and emissions of pollutants
and noise, pollutants dispersion and noise propagation, exposure to pollutants,
noise and accident and related risk assessment, impacts on monument assessment
and a tool for the overall analysis.
These modules are integrated by a software Manager, a Suite Data Base, a
commercial GIS and a user-friendly interface.
This integration represents a
significant technical achievement.
Standard model suites normally include only a
few of these models.
The suite represents a strong enlargement of the applicability area, since with
this kind of ‘multi-impacts’ tool the user is able to analyse in an integrated and
‘coherent’ way the various aspects of ‘global’ urban policies, without having to
perform separate studies relying on different input information providing less
Beside the integration, the scientific core value of the
ISHTAR Suite is represented by a few crucial modelling developments that can
be summarized as: prediction of the effects of citizens’ reaction to postulated
measures; improvement of vehicle emission modelling; development of an urban
road safety model; a tailed estimate of pollution effects on citizens’ health based
on the spatial-temporal analysis of population, noise and pollution maps.
The high spatial and temporal flexibility in the use of the Suite maximizes the
possibility of application from local short-term actions to widespread long-term
policies, thus being of interest for different categories of users.
The suite is going to be tested in the seven cities involved in the ISHTAR
Project: Athens, Bologna, Brussels, Graz, Grenoble, Paris and Rome.
