Transportation systems impact health outcomes in several ways: 1. Vehicle emissions and traffic congestion negatively impact air quality, which can lead to increased health risks like cancer, heart disease, and susceptibility to disease. 2. Lack of access to affordable and reliable public transportation makes it difficult for people to access healthcare. 3. Communities can improve health by developing equitable transportation networks that provide safe walking, biking, and public transit options for all residents to access services and enable healthy lifestyles.
