CBTC drives the trains and a driver still sits in the cab. Congestion on served corridors fell 34.9% a year after opening; residents beside the line did not measurably change how they travel.

Indonesia's first metro opened on 24 March 2019: 15.7 km and 13 stations from Lebak Bulus to Bundaran HI, financed by a Japanese ODA loan that the national government repays 49 percent of and Jakarta province 51 percent. CBTC signalling drives the trains automatically, but a driver stays in the cab — GoA2, not driverless. Every station has platform screen doors; fares run on JakLingko cards, bank e-money, the MyMRTJ app and NFC QRIS Tap. Daily ridership fell from 86,000 in 2019 to 19,700 in 2021, then passed 130,000 in late 2025. Phase 2A, once due in 2025, now targets Monas in 2027 and Kota in 2029.

📊 Impact

Evening-peak congestion on served corridors fell 33.6% six months and 34.9% one year after opening, measured against control corridors by difference-in-differences on Google Maps travel times; a paired two-wave panel survey found no statistically significant change in nearby residents' own vehicle use.

🎓 Lesson

Automatic train operation still needs a driver in the cab, and a line that measurably eased its own corridor did not measurably change how the people living beside it travel.
