Indonesian President Joko Widodo inaugurated the country's first mass rapid transit (MRT) system on 24th March. The aim is to ease the traffic congestion in the capital Jakarta. He also presided over a groundbreaking ceremony to mark the beginning of the second phase which is planned for completion by 2024. Passengers can ride for free until the end of the month. Jakarta is one of the top three traffic-congested cities in the world, according to a traffic index developed by the navigation systems company TomTom.
