The use of noise maps of the city for selection of management decisions about the regulation of road traffic
The important problem is protection of population from high noise. This problem was discussed in the article. Also in the article was showed the necessity of the noise maps of the city for making correct management decisions is proved. There are presented data on the change in the number of vehicles on the territory of the European Union and Russia, information about noise levels in the territories along the roads in the cities of Russia, the algorithm for generating noise maps of the city. There were estimated noise levels generated by vehicles, in the Central part of the city of St. Petersburg for two scenarios: first on the basis of field studies on the composition and intensity traffic, second - on forecast of limiting vehicle traffic. Conclusion: restriction of movement of vehicles can reduce impact, noise, and values of the maximum concentrations near streets with restricted movement, but at the same time can increase the negative impact of the near streets, where will be redistributed transport stream. The decrease in the maximum ground level concentrations and levels of noise for such a big city like St. Petersburg will contribute to complex of environmental measures: improving fuel, classes environmental performance of vehicles, the development of the road network with traffic organization based estimate of environmental consequences of the proposed activities.
