Transportation

In general, San Francisco public transportation seems well-developed, and the  San Francisco Department of Public Health has addressed essential considerations such as noise annoyance, vehicle-pedestrian collisions, and mortality attributable to air pollution, using inputs such as traffic volumes and population changes. My personal experience of using public transport is rather low because I have a foot injury and have always preferred a car. Otherwise, my foot becomes swollen due to standing and hurts. I understand that my behaviors do not contribute to the improvement of the air quality. However, I have recently decided to try biking and will do as soon as I get a bicycle. What concerns me still is that there are many hills in my are and in the city, so I am not sure how I will cope with it. Nevertheless, it worth trying!
