Janette Sadik-Khan, New York City Transportation Commissioner
An urban visionary who cuts through the gridlock.
Clarification, Aug. 9, 2011: In an ill-used figure of speech, this article originally noted that Sadik-Khan's job is to, "Keep the traffic moving and the trains running." Technically, the job of NYC transportation commissioner does not involve any trains. That job falls to the MTA. (Return to the sentence.)
