GREATER LYON WORK
Each
partner of the project chose its own organization in order to
carry out the noise maps covering its territory. This page
presents the provisions, including GIpSynoise, taken by Greter Lyonto lead its Environmental Noise Management.
In collaboration with Acoucité, Greater Lyon chose 3 tools:
- Gipsynoise, for the development of the noise map on the
agglomeration, in accordance with the french regulation ;
- a Urban Noise Monitoring network, including 19 fixed beacons and 10
mobile beacons, for a more precise vision on degraded zones, or
presenting a inheritance, or to follow an
urban project;
- thematic and/or local survey with investigations of perception.
The use of the GIpSynoise tool highlights the following elements, those are characteristic of noise mapping achievement:
- the data necessary make noise maps are heteroclite, not complete, the
date of production of the data is often different, and especially the
format necessary to Gipsynoise is never available.
Greater
Lyon thus defined routines of transformation of the geographical data
with a tool named FME. You will find information about this tool on the
following site: http://www.safe.com/products/fme/index.php.
This tool is available in French version at http://www.veremes.com/
Generally, the following data were approximated:
- the data of road traffic are estimates resulting from software of
simulation taking of account vehicles countings, investigations
origin-destination and the road's capacities.
-In
order to be expressed in accordance with method SRMII, the data of
traffic rail were interpreted using the Recommendation of theCommission of August 6, 2003 (Official Journal of the European Union).
- the industrial noises are still in the course of treatment, within
sight of the complexity of examination of the decrees of authorization
of the 400 ICPE of Large Lyon.
The Noise Mapping Guide of the CERTU and of the European Commission were really usefull.
