More than 1.25 million people are killed and up to 50 million are injured on the world’s roads every year (World Bank, 2019).
At the same time, transportation produces emissions that contribute to air pollution and climate change. Its infrastructure has serious impacts on ecosystems. Transport accounts for about 64% of global oil consumption, 27% of all energy use, and 23% of the world’s energy-related carbon dioxide (CO2) emissions. Each year, almost 185,000 deaths can be directly attributed to vehicular pollution. More than 1.25 million people are killed and up to 50 million are injured on the world’s roads every year (World Bank, 2019).
