One piece of the sprawl solution...

...continues to develop in the D.C. area:

Metrorail ridership grew faster among District residents in the past five years than among residents of any other jurisdiction in the transit agency's service area, according to a rail passenger survey.

Residents of the District -- where 40 of 86 stations are located -- took an estimated 192,503 trips on a typical weekday last spring, up 17 percent from five years before. By comparison, riders living in Montgomery and Prince George's counties took 249,856 trips, up 8 percent, and residents of Metro's five Virginia jurisdictions logged 190,740 trips, a 4 percent increase.
