Rail

In the scope of environment and transport management, we help public authorities to characterize the current acoustic environment, to study various hypothesis of evolution and to identify the best possible configurations. Before implementing a project, we also achieve impact assessment studies so as to check the project compatibility with its overall environment as well as with the economical facts.

CHARACTERISATION OF THE ACOUSTIC ENVIRONMENT

Nowadays, the quality of the environment is one of the population’s major concerns. The European regulations now compel every state member to identify the noise levels on its territory.

To master noise is our profession. It is therefore logical that our first competence be to identify, characterize and illustrate it. To do so, we have :

MODELLING THE EVOLUTION OF THE ACOUSTIC ENVIRONMENT AND DECISION ANALYSIS

What socio-economical evolution will experiment the country?
Where will be located the new urban, commercial and industrial development areas?
What will be the impacts in terms of mobility and public transports?
This is just an example among the many questions to be solved by public authorities.

By modelling the various scenarios of evolution for the acoustic environment (modifications in type of rails, maximum speeds, rolling stocks …), we help them to identify the best project configuration.

As a result of a sustained research and development policy and of more than 20 years of experience in the area, our unique service offer combines :

PROJECT STUDIES: IMPACT ASSESSMENT

Before implementing a project, public authorities need to check whether the decision to create or to modify the transport infrastructure is compatible with its overall environment. The economical viability of the project must also be confirmed.

With more than 500 references in the area of transports, we smoothly integrate any multidisciplinary team and work together in order to reach the final validation of the project.

In the scope of environment and transport management, we help network managers to characterize the current acoustic environment, to study various hypothesis of evolution and to identify the best possible configurations. Before implementing a project, we also achieve impact assessment studiesw so as to check the project compatibility with the overall environment as well as with the economical facts.

With more than 500 references in the area of transports, we smoothly integrate any multidisciplinary team and work together in order to reach the final validation of the project.

In the implementation phase of the project, we work in partnership with the engineering teams for drafting the specifications requirements, as well as the drawing of details in accordance with the acoustic objectives.

We bring a significant added value thanks to our proprietary tools : modelling softwares and references databases.

Doing so, our target is to provide solutions balancing quality, cost and long-term performances.

What must be the shape of noise protections when positioned in a rail bend, in a cutting or upon a bridge?
Will it have the same effect whether it is made of wood, concrete or metal?

And what if it is transparent or opaque? For every single case, we help building contractors to find the optimum answer.

Designing noise protections is our core business. Our software MAP 4D Design® is for years the only one in the market to fully guarantee the optimisation of shape and materials of noise protections.

We also bring our unique experience in the area, acquired in particular via our role as convenor of the European Standardization Comittee for noise reducing devices (CEN TC226/WG6).
