Worst traffic I've been in lately was in Accra, the capital of Ghana (west Africa). This is a city of 2 million plus, with a poorly developed road system and infrastructure, and an abundance of barely-running minibuses, taxis, trucks and private cars. It is not uncommon for downtown workers who live on the outskirts to leave home at 5 or 5:30 am to be at work by 9, such is the level of congestion.
