The paper dwells on examining and testing a mechanism for determining exposure to transport noise followed by dividing an area of a large industrial city with population exceeding 1 million people into specific zones as per health risk criteria. Noise spread was modeled with ?Ecolog-NOISE? specialized software basing on a vector map of the city and using geoinformation systems. To create a database on transport noise sources, the authors collected and analyzed data on traffic intensity on city motorways. Basing on...
