Twin Cities Noise Pollution Model
A PostGIS-based noise pollution propagation model for the Twin Cities metro area replicating European noise mapping standards for the Twin Cities. This project models combined transportation noise exposure from roads, rail, and airports across 2,380 schools and 817 census tracts. A custom distance decay function built in PostgreSQL calculates estimated noise levels at each receiver location, flagging sites that exceed the WHO 65 dB threshold for significant noise impact.
