Wiehle-Reston East gets the most passengers overall
Wiehle-Reston East currently handles the lion's share of passengers at new Silver Line stations, partly because it's a hub for transit riders whose bus routes take them there or who use the station's large park-and-ride garage. Wiehle-Reston East's ridership base is a lot like other stations at the end of Metro lines: the overwhelming majority of its riders are inbound commuters who enter on weekday mornings and exit on weekday evenings.
Interestingly, Wiehle is also the largest single commuting destination on the Silver Line. On the average weekday during the morning peak, about 1,000 passengers exit at Wiehle, compared to about 5,000 entries. Even though Tysons Corner is a jobs hub, only about 900 people exit at that station during the same period. At the four stations in the Tysons area, there are about 2,100 combined exits during this period.
The Wiehle number is impressive because more people exit at Wiehle Avenue during the morning peak than exit from any other terminal station. Wiehle's 1,046 average exits trumps the next-best terminal, Shady Grove (with 977 average exits).
Also interestingly, Wiehle's ratio of entries to exits is the smallest of all the terminal stations (meaning it's the most tilted toward exits). At Wiehle Avenue, for every exit, there are 4.9 entries. That compares to 6.1 entries for every exit at New Carrollton, 7.3 at Greenbelt, and 7.5 at Largo.
Some of this ridership is likely due to people connecting to buses bound for Reston, Herndon, and Dulles Airport. But there are some office buildings around the station as well.
Ridership at Wiehle will likely change once Phase Two is complete: many passengers who currently arrive on buses, or take them to destinations like Reston Town Center or Dulles, will instead start boarding the Silver Line farther down the line.While it is reasonable generates more morning boardings than other SL stations because it is at the end of the line, it is pleasantly surprising that it also generates more morning exits than any other endpoint station in the system as well as major job hub Tysons. Apparently, Reston IS a destination!
