USC today unveiled a study that concludes that folks who live within a half-mile of one of the line's stations reduced their auto travel by about 11 miles a day.
But wait, there's more:
USC says those station-adjacent neighbors also tripled the number of miles they traveled by rail. And they went from about one daily rail trip per household to three, the university found.
Lead author Marlon Boarnet of the USC Price School of Public Policy:
Los Angeles has made a large commitment to rail transit, and this study is the best evidence to date that persons near rail lines are driving less. People have been wondering if anyone will change their travel habits in the wake of more rail transit, and this says the answer is clearly yes.
The first "experimental" study of Expo's effects had USC academics following 200 families along the line both before the train opened and after, in fall 2012.
Researchers say those Angelenos living near the Expo Line reduced their own carbon emissions by 30 percent.
Exercise among those folks increased by about 9 minutes per day (because of ... walking to the train stop), the study said.
The greatest ridership was at stations that were also bus-line-adjacent, the researchers said.
The study concludes that the increased ridership confirms that development along transit lines is logical and that the investment in local light rail could be worth it:
The Expo Line is associated with travel behavior change ... This is some optimistic evidence for the rail transit investment program in Los Angeles.
