To better understand whether and where Bus Rapid Transit (BRT) could work in the region, the Barr Foundation convened the Greater Boston BRT Study Group. Made up of diverse stakeholders and transit experts from across the city, the BRT Study Group partnered with the Institute for Transportation & Development Policy to investigate the possibilities for implementing BRT throughout the metropolitan area. The report presents the results of the group's analysis, and further explores how BRT at its highest standard could improve mobility, equity, and sustainability for residents, commuters, and visitors.
