The Detroit metro area has seen its population decimated in recent years, but the need for transit hasn't gone away.
"On certain lines, ridership has skyrocketed," said Tiffany Draper, a transportation planner with the Southeast Michigan Council of Governments. "But overall, ridership has been pretty steady."
Figures from the American Community Survey show a 30% increase in commuting by transit between 2006 and 2008 in the Detroit metro area, though Draper says the boost was likely a reaction to rising oil prices.
