There is one inescapable reason that a regional mass-transit system will not succeed in the Indianapolis area.
“Put simply, mass transit needs mass – i.e. density.” And we don’t have it.
The quotation comes from two experts in urban transit: Erick Guerra and Robert Cervero of the University of California at Berkeley. They studied 59 rapid bus transit, light-rail and heavy-rail systems in 19 metropolitan areas. Their lesson: For mass transit to be cost-effective, job density and residential density must be high along the way.
