Good point Hive account@solarguy! Noise can be prevented! The main responsible agency to prevent traffic noise is the City Administration and the Federal Administration. So, it is local responsibility and national responsibility. However, corruption lobbying and the deterioration of governance morals prevent them from acting on the issue. They will act on the privileged basis if the issue of noise is affecting them directly. Ex. If the President or Governor or someone of importance visits a town, they will manage and re-direct traffic so they will not be bothered. We are living now in 2016 under a Republican and Democrat's corruption, not only on the noise issue but in many parts of the government. It is time for the people to act!
