Sustentabilidade na última milha da distribuição postal em áreas urbanas mediante adoção de triciclos elétricos

The demand for transport services around the world is a phenomenon that is directly related to the urbanization process progresses. However, the intensive use of vehicles accentuates problems related to the last mile deliveries and pollutant emissions. This study aims to assess the sustainability obtained using electric tricycles in the postal delivery of Rio de Janeiro. Results indicates a 27.86% reduction in total transport costs, as well as reductions in monthly emissions of atmospheric pollutants per route by 10.11 g of CO; 32.78 g of NO X ; 0.02 g of RCHO; 0.7 g NMHC; and 0.33 g MP, while monthly reductions of CO 2 eq emissions per route are 21.01 kg. Regarding the social aspects, the heart rate of the postman is constant throughout the operation, while, in the traditional intermodal distribution, there was a greater variation of the heart rate during the entire delivery process.
