Traffic in Tyson's Corner

Traffic is bad in this area, without doubt. It is especially bad in Tyson's Corner. An October 24 article in the Washington Post stated that the Tyson's Corner lunchtime rush “surpasses the morning rush by 24 percent.”

How did they get that statistic? See the
chart of traffic in Tyson's Corner.

You will notice that they define a lunch “rush hour” that is 25
percent longer than the morning rush hour (2 1/2 hours versus 2 hours).


However, the traffic rate (cars per hour) is almost the same. Dividing the total number of cars by the duration of the rush hour yields 9,359 cars per hour between 7 a.m. and 9 a.m., and 9,268 cars per hour between 11:30 a.m. and 2 p.m. The evening rush also has the same rate: 9,343 cars per hour between 4 p.m. and 7 p.m.
