In addition to reducing congestion, public transport also plays a crucial role in improving air quality. Private vehicles are a major source of air pollution, emitting harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. These pollutants contribute to respiratory problems, cardiovascular disease, and other health issues. By encouraging the use of public transport, cities can significantly reduce their carbon footprint and create a healthier environment for their residents.
