Noise Models

3D noise model in Rosensteinviertel, StuttgartThe Rosensteinviertel redevelopment project involves proposals to move all the train lines crossing the centre of Stuttgart underground and it has been estimated that during the construction phase, one truck every forty-five seconds will pass through the residential area to deliver materials to the site. This traffic movement will affect the people living and working in the area.

As part of the VEPs project, the Centre for Scientific and Technical Building Research (CSTB) has produced 3D noise simulations to help people visualise and understand the noise pollution associated with the construction traffic. 

 

These simulations can be viewed as either:2D noise model, Stuttgart

 

VEPs partners are currently investigating how these noise simulations can be visualised in a 3D city model available online.

About the simulations

These simulations are based on:

  • statistical information about predominant weather conditions (wind, humidity);
  • estimates for road traffic (number of vehicles per hour, average speed, percentage of trucks);
  • predictions of train traffic (number of trains per day, train types and speed).

The data is imported into MITHRAź, the noise simulation software developed by CSTB, which computes sound levels on the ground and on the facades of buildings.

These simulation results are then processed into the Enriched Virtual Environments (EVE) software platform to produce textured sound maps and to build an interactive visualisation that allows users to display different simulation results and to fly through the 3D scene.

Currently the noise simulations take two weeks to process. CSTB research is focusing on ways to speed up the simulation results.
