MapNoise

GIS-based Traffic Noise Prediction

MapNoise is an advanced GIS application for performing calculations of road traffic noise using digital maps as data input for performing the noise propagation calculations.

Noise propagation is being calculated in accordance with the common Nordic Prediction Method for Road Traffic Noise. MapNoise calculates the equivalent sound pressure levels (LAeq) as well as maximum sound pressure levels (LAmax).

MapNoise may be utilised for calculating the sound pressure levels at ground levels and at the front of buildings at any level.

MapNoise Capabilities

MapNoise is a powerful tool with the following capabilities:

It can extract all information required for the Prediction model from a digital map containing contours, road centrelines, buildings and noise screens. This ensures that all calculations are carried out using the same data source.

The calculations are carried out quickly and efficiently and with a high level of detail, including screening and reflection effects of terrain, buildings in one or several storeys and noise screens.

The model results are instantly visualised on maps.

Noise Propagation - Terrain and Reflections

MapNoise can even deal with noise propagation in complicated terrains. A model of any terrain can be created automatically based on digital contour lines, level points etc. This makes it possible to include screening and reflections from the terrain in the calculations.

MapNoise- fields of application

MapNoise is beneficial for

EIA and SEA studies

General planning, mapping and policy making

Infrastructure planning

Assessments of environmental effect of different planning and mitigation measures

Local physical planning e.g. to secure that noise limits will be respected in residential areas

Environmental indicators concerning sustainability

Design of noise screens
