Bus rapid transit (BRT) needs space, not just for buses to run quickly and reliably, but for stations, supportive multimodal infrastructure, stormwater treatment and other features. This space is never easy to come by, especially in “legacy cities,” where road rights-of-way were first established for carts and wagons and hundreds of years of urban development has risen up around them. Hear how three major metro areas are developing BRT in constrained, historic, urban corridors. How are they negotiating priorities and allocating limited dollars? What’s the decision-making approach when space is tight and everyone's needs and wants can’t be met? How is future mobility finding a path?
