"A new report, released by the American Public Transportation Association, which surveys current research has found that people who live in communities with high-quality public transportation drive less, exercise more, live longer, and are generally healthier than residents of communities that lack quality public transit."
One of those studies with a 'duh' conclusion. But in this age of skepticism, every such study helps. As the study concludes, "this analysis can help transport and health professionals better coordinate their efforts to create communities where people can live long and prosper…. When all impacts are considered, improving public transit can be one of the most cost effective ways to achieve public health objectives."
