Summary:

Researchers studied the effects of the Twin Cities’ Metro Transit Green Line light rail transit on automobile traffic on parallel and adjacent roadways. Using annual average daily traffic data from before and after the Green Line’s opening in 2014, researchers showed that the light rail transit line decreased automobile traffic on nearby roads as light rail ridership increased each year. In addition, a 2016 Metro Transit on-board survey of nearly 2,000 park-and-ride users guided researchers in developing a model to assist planners in effective design and placement of park-and-ride facilities.
