Park-n-Rail will be a godsend to these cities suffering with lower subway ridership. We estimate that the first Park-n-Rail location at the intersection of I-270 and I-370 in Maryland will increase Metro ridership by at least 33,000 one way trips per day or 66,000 round trips.

With an approximate fare of $14.00 round trip, total revenues will be at least $462,000 per day or $120 million per year. When 4 additional Park-n-Rail stations go on line in the Washington DC area in later years, revenue will increase substantially.
