Trivia thanks to Jon Lee Anderson's "Can Iran Change?" in "The New Yorker's" latest Letter from Tehran. The answer is B).
Why traffic control? The answer, inexplicably, could be eschatology. Anderson explains:
This explains Ahmadinejad's evangelizing allusions to the "promised one" when he has addressed the U.N. General Assembly. His public zeal has earned him criticism from Iranians at home ... A senior Iraqi politician who has met Ahmadinejad a number of times said that, at a meeting in Tehran two years ago, Ahmadinejad spoke about little but the Mahdi. The politician heard from others that Ahmadinejad had blueprints for a planned triumphal superhighway and reception point in Tehran, to be built for the Mahdi’s eventual arrival."
