Traffic jam in Indonesia's capital of Jakarta cost the city at least 28.1 trillion rupiah (about 3 billion U.S. dollars) each year, a senior official said here on Thursday.

"The greatest loss, amounting to 10.7 trillion rupiah (about 1. 1 billion U.S. dollars) per year, is related to fuel," Transportation Ministry Inpector General Iskandar Abubakar said during a discussion on mass transportation systems in Jakarta.

The notorious traffic congestion also inflicts losses of at least 9.7 trillion rupiah (about 1 billion U.S. dollars) in lost productivity, while losses related to health reached 5.8 trillion rupiah (about 650.2 million U.S. dollars) and public transportation owners suffered 1.9 trillion rupiah (about 219 million U.S. dollars) in losses, the tempointeraktif.com reported.

As of last December there were more than 11 million vehicles in Jakarta, comprising 9 million motorbikes, 3 million cars, and 63, 000 public transportation vehicles.
