Traffic congestion is common in large cities and on important express roads, which imposes travel time delays, an excessive fossil fuel consumption, an increased environmental pollution, etc. Related to it, traffic incidents such as broken-down vehicles, accidents and flat tires intensify the traffic congestion because they generate irregular but frequent interruptions. Thus, it is necessary to implement studies that seek to minimize the impacts of incidents. Therefore, this chapter seeks to apply the MEET model (Methodologies for Estimating air pollutant Emissions from Transport) to analyze the impact of incidents on carbon dioxide (CO2) emissions on express roads. For conducting the case study tests, real data are used from approximately 2,800 incidents on Avenida Brasil, the main expressway in the Rio de Janeiro city, which were provided by the Traffic Engineering Company of the Rio de Janeiro city (CET-Rio). The results indicate that incidents increase in 22% the CO2 emissions, that the broken-down vehicles are the incidents with the greatest impact on these emissions due to their high frequencies, and that the morning and afternoon peak hours are responsible for 82.4% of the increase in CO2 emissions related to the incidents. In addition, using Kernel maps, it is possible to verify the sections with the highest incidents, as well as CO2 emissions.
