How can building a mass transit system improve living standards in an urban area?

Building a mass transit system can significantly enhance living standards in urban areas by improving accessibility and mobility, allowing residents to reach jobs, education, and services more easily. It reduces traffic congestion and lowers pollution levels, contributing to a healthier environment. Additionally, efficient public transportation can stimulate economic development by attracting businesses and creating jobs, while also making housing more affordable by reducing the need for personal vehicles. Overall, a robust transit system fosters greater social equity by connecting underserved communities to essential resources.
