For the last few years, the city of Macaé has been suffering an impact on urban traffic due to increasing in number of vehicles. Between December 2010 and June 2011, for example, there was an increase of 1,974 cars (DETRAN-RJ, 2011). The oil industry caused a population growth of 159,507 inhabitants in the city between 1970 and 2010 (IBGE, 2012; TERRA e RESSIGUIER, 2011). With the increase in passenger transport demand, besides the increase in number of cars, the quantity of buses also registered a duplication of fleet between 2008 and 2011 (MELO, 2008; SIT, 2011). This study approaches a comparison between air pollutant emissions from cars and buses, the most commonly used transportation in Macaé. Despite an increase in number of cars, buses present a better cost-benefit because of pollutant per passenger-kilometer factor.
