With 20 million vehicles on the streets each day, and with far less pavement than in big cities like New York, Singapore and Tokyo, traffic in Jakarta is terrible. Deden Rukmana, who teaches urban planning at Savannah State University, says the population of the world’s sixth largest metropolis has been growing so fast that the city can’t keep up.

“In 2000, they had 20 million and in 2010 up to 28 million. There is a study showing that Jakarta will have total traffic gridlock by 2014,” he said.

To reduce the number of cars on the road, lawmakers have designated several main arteries as what they call “Three in One zones.” During the morning and afternoon rush, you can’t drive there unless you have at least three people on board. That’s why, near the entrances to the zones, men, women and children line up – raising their index finger – offering to rent themselves to commuters in a hurry.
