A study performed by USC reaffirms what transit advocates have said all along: Providing quality rail transportation reduces vehicle usage and pollution. The study specifically looked at car use before and after the opening of the Expo Line to Culver City. Of note, those who live within half a mile of a station reduced their driving by 40%, traveled 10 to 12 miles less per day and increased transit use threefold. Access to transit also increased physical activity by adding time spent walking to stations. In turn, these same individuals reduced their carbon emissions by 30%. While it is not reasonable to expect the majority of Southern Californians to be within an earshot of a rail station, the study demonstrates that better transit can improve people’s lives in tangible ways.
