President Joko “Jokowi” Widodo launched the Greater Jakarta light rapid transit (LRT) on Monday, heralding the beginning of its service connecting Jakarta and two satellite cities as part of efforts to alleviate chronic traffic in the capital and the worsening air pollution.

The new LRT network spans 42 kilometers and its trains stop at 18 stations along two lines. The Bekasi Line starts at Jatimulya Station in Bekasi, West Java, and the Cibubur Line from Harjamukti Station in Depok, also in West Java. Both lines end at Dukuh Atas Station in Central Jakarta.

“We hope that people will flock in crowds and switch their commute to the LRT [so that] traffic congestion can be avoided and pollution can be reduced,” said Jokowi.

Jakarta has consistently ranked among the top 10 most polluted cities in the world since May, according to data from Swiss air quality technology company IQAir.

The Greater Jakarta LRT’s coming into force will thereby complete the government’s series of mass transportation projects, which includes the Jakarta MRT, the Commuter Line train, TransJakarta buses and the airport-bound trains – all of which have already been in operation for years.

These projects aim to encourage people to start moving away from their personal vehicles, Jokowi said, adding that the number of daily public transportation users had yet to reach the ideal target.
