ADVANCE FOR USE MONDAY, OCT. 1, 2012 AND THEREAFTER - In this Wednesday, Aug. 15, 2012 photo, traffic backs up along a busy road in Lagos, Nigeria. In the metropolis of 17.5 million, which is predicted to overtake Cairo as Africa's most populous city in 2015, the traffic jams that Nigerians call "go-slows" can strike at any moment.
