“…A linha preta corresponde à função de correlação do consumo de combustível e velocidades para os ônibus convencionais proposta. Contudo, estudos experimentais (ANTUNES, 2009;FREY et al, 2007;SIMÕES;CUNHA, 2006) indicam que é preciso existir uma correlação mais universal que contemple as velocidades mais elevadas, mas especialmente as velocidades abaixo de 15 km/h (Figura 2). A equação (1) representa a correlação de consumo para todas as condições de velocidades, proposta pelo estudo, para ICB.…”

O crescimento das emissões de poluentes no setor transportes, fruto do incremento da frota de veículos em circulação no país, motivou sobremaneira a elaboração deste trabalho, que se propôs a comparar o consumo de combustível, consumo de energia e emissão de CO2 equivalente de duas tecnologias alternativas ao uso de combustíveis não renováveis – os ônibus híbridos e elétricos. Foram propostos sete cenários nas rotas do Gama, Ceilândia, Sobradinho, Taguatinga e Jardim Botânico. O estudo propôs três métodos de cálculo que podem ser utilizados para ônibus urbanos. Quanto aos resultados constatou-se que, em termos de emissão de CO2, o ônibus elétrico tem um potencial poluidor 64,7% menor do que o ônibus movido a diesel. O ônibus híbrido tem o potencial de emitir 23,9% menos CO2 e consumir 18,8% menos combustível que o convencional. Os resultados mostraram que não houve diferença entre a inserção de novas tecnologias em rotas fora do horário de pico. A partir dos resultados, discute-se a importância da priorização de fontes renováveis na matriz energética brasileira, com vista a uma maior utilização de combustíveis alternativos.

“…Due to the high volumes of vehicles in urban areas a vast body of mobility research has been developed to measure and evaluate the pollutants exhaust emissions from vehicles (Boriboonsomsin et al, 2012, Song et al, 2013. As the reduction and estimation of these emissions will led to a better quality of life in urban areas.…”

Abstract. In developing countries, metropolitan cities, due to their economic activities, attract an increasing amount of commuters on a daily basis. This has led to major freeways and roads experiencing high levels of congestion and consequently high pollution levels. In 2020, due to a global pandemic of an outbreak of Corona Virus (COVID-19), the national government declared a national shutdown with only essential traffic being allowed to operate. Given the scenario of the national lock-down this allows for the statistical analysis of the impact of essential traffic on the overall transportation system. Consequently the aim of the paper was to assess the congestion and CO2 emission impact of essential traffic for the City of Johannesburg. Using an exploratory approach, we monitored and collected traffic congestion data from the Tomtom traffic index for the metropolitan city of Johannesburg, South Africa. We develop a relationship between congestion and pollution to visualise the daily variations in pollution and congestion levels. We demonstrate this by comparing variations in congestion levels in two epochs, viz the period without movement restrictions and the period whereby movement is restricted. The results reveal essential traffic on the congestion index to be below 22 percent for both weekends and weekdays. A scenario common only during weekends in 2019. Whilst for the emission index, CO2 levels are approximately less than 45 percent throughout the week. The paper concludes the investment into mining and analysing traffic data has a significantly role for future mobility planning in both the developed and developing world and, more generally, improving the quality of commuting trips in the city.

It was found that the heavy metal concentrations and their ecological risk indices decreased exponentially with increased roadside distance, with a moderate level of ecological risk within a 10 m roadside distance.…”
