The management of the traffic noise within the Metropolitan District of Quito has
been tried indirectly, only as an indicator of air pollution control. However, studies have
forgotten the evaluation of human health effects and the magnitude of the polluting
agent in the city. The increase of vehicles of 12% annually has saturated the roads, and
the traffic noise is more in an urban zone at the District. For this reason, the present
project had the objective of designing statistical models of traffic noise in DMQ with
historical data from 2009-2015, and its subsequent verification with data from the
Environment Secretary of the DMQ to 2019, applying simple and multiple linear
regression analysis. A database and an analysis of the behavior of noise in recent years
carried out, influenced by the traffic flow in the city, establishing a relationship between
the number of vehicles and the equivalent noise. Finally, the validation and evaluation
of the models performed employing confidence intervals and least squares regression
by calculating the correlation coefficient of these models and validating them through
the analysis of variances (ANOVA) that allowed determining the magnitude of the
relationship between the variables and the effectiveness of the model. The result from
the investigation determined the noise maintains a variant tendency, which is related
to the number of vehicles circulating in the streets of Quito as well as the speed of the
same ones. It’s evident that during the day the noise frequently changes until six o’clock
in the evening and from seven o’clock at night, the noise decreases as a function of the
diminution of the vehicles. For that reason, the simple linear regression models, as well
as the zonal and integral multiple models, adjust to the conditions of the urban area
South, Center, and North of the Metropolitan District of Quito.
