Emisiones vehiculares mediante modelo din?mico de sistemas en la carretera Central en la ciudad de Lima- Per? noviembre 2020

Introduction: The greatest air pollution such as total organic gases and micrometric particles is caused by the automobile fleet; this reality is shown through a system dynamics.Objective: The objective of the research was to estimate the vehicular emissions generated and released into the atmosphere in the Central Highway in the eastern part of the city of Lima, Peru.Method: The data was obtained during 35 continuous days in November and December 2020. Then a dynamic systems model was developed in the VENSIM PLE 8.2.1 software, variables of activity levels were entered such as the number of vehicles grouped in categories and factors of emission relative to speed acquired from EMEP / EEA 2019.Results: 853 670 vehicles were counted, of which category B corresponding to four-passenger light vehicles represent 59.18% of the total. The model estimated CO2 as the main gaseous agent that is emitted into the atmosphere with a total of 632982 tons, three agents present average emissions CO, HCT and NOX with 174.14, 66.57 and 41.55 ton respectively, the lowest emissions are PM10, CH4, SO2 , N2O and NH3 which generated 1.46, 0.9, 1.88, 0.15 and 0.02 tons respectively.Conclusions: The greater pollution causes category B vehicles than corresponding to four-passenger light vehicles with CO2, CO and HCT emissions, category G, which are heavy trucks greater than 16 tons and category A Motorcycles also add to these emissions to a lesser extent.
