To: Sully- who wrote (74145 ) 9/16/2009 1:03:49 PM From: Sully- Respond to of 90947 The 9/12 Crowd Estimates By: Mark Hemingway The Corner Yesterday, I posted a letter from a transportation planner: <<< The Obama inauguration saw around 1.1 million Metrorail trips, compared to a normal winter Saturday of around 150,000-150,000 (source: Metro website). Assuming this group rides Metro at the rates of other political demonstrators, Fourth of July celebration riders, and run of the mill tourists, I'd guess you'll get around 40%+/- arrived/departed by subway. Therefore, if there were 150,000 9-12'ers PLUS the normal tourist loads, there should be around 420,000-430,000 Metrorail riders reported for the 12th—compared to about 300,000 typical riders on a Summer/Early Fall Saturday in D.C.,; if there were 250,000 9-12'rs, Metrorail ridership would have been around 500,000 that day. >>> Today, Mary Katherine Ham tweeted the ridership numbers from the DC metro: <<< Got Metro ridership #s for 9/12 from Taryn McNeil at Metro: Rail: 437,624 and Bus: 236,347. >>> And according to Mary Katherine Ham, here's the average metro ridership this summer: <<< Average Saturday Metro #s for this summer: Rail hovers around 225-250K; Bus around 150K. >>> NB: That's significantly lower than the 300k the transportation planner was assuming. Obviously, there are many more factors to take into consideration, but I think it's safe to say the crowd easily topped 200k. UPDATE -- a reader makes a good point: <<< I see the the transportation planner adjusted for seasonal variations, which is good, but in his comparison to Obama's Inauguration, I don't see him mention anything about how I-395, the GW parkway, and every bridge from Virginia were closed that day. If you wanted to get into the District for any purpose, including work, you had to take the Metro, a taxi, or a limo. Not so for 9/12. >>> corner.nationalreview.com
