Noise Maps

Use noise maps in your concept development phase to help evaluate project alternatives.  High resolution georeferenced countour maps of transportation noise can be generated across large or small areas.   Noise values represent the effect of average daytime traffic volumes, approximated by samples from roads with similar profiles.

City Wide Estimation

Maps can be generated for areas of various size: city-wide, local area, project area, or anywhere in between.  The following is an example of a city-wide map.

Resolution
10 meter pixels

Local Area - Traffic

The noise estimation model features an ability to calculate the sound attenuation due to solid structures.   This capability helps identify "noise shadows" behind buildings and solid structures.

Local Area - Rail

Railroad noise maps can also be generated, representing the noise envionment when a train is passing.  This example shows the noise due to both light and heavy rail across the same area as the previous example.

Enables planners and project teams to be more creative in how they approach projects.  With more detailed information and early estimates, teams are able to showcase more innovation, highlight alternatives, and help differentiate your proposals.
