World Health Organization (WHO) - transport health impacts

The World Health Organization (WHO) highlights how transportation affects health by influencing air quality, safety, and physical activity. Badly maintained vehicles and congested roads release pollutants that can cause respiratory and cardiovascular problems. Traffic accidents are a leading cause of injury and death worldwide. Additionally, reliance on motorized transport reduces physical activity, contributing to obesity and related diseases. Improving transportation systems—such as promoting cleaner fuels, better safety measures, and active travel options—can significantly enhance public health and reduce preventable illnesses and injuries.
