The idea was born from desperation, not ambition. In 2001, Governor Sutiyoso proposed four mass transit options for Jakarta: an MRT, a monorail, a bus rapid transit system, and water transport. The MRT would have been ideal, but Indonesia had just lost investor confidence after the fall of Suharto's regime in 1998, and no foreign lender would fund a subway in a country still stabilizing. The monorail broke ground in 2004 and was permanently canceled a decade later. Water transport remained a concept on paper. That left the bus -- the one option that did not require foreign investment, the one that could be built with concrete lane dividers instead of tunnels. On January 15, 2004, TransJakarta's first corridor opened between Blok M and Kota. It was free for two weeks. Then it started charging 3,500 rupiah -- about twenty-seven cents -- per ride. Twenty years later, the fare has not changed.
The blueprint came from the other side of the Pacific. Bogota's TransMilenio, which opened in 2000, had demonstrated that dedicated bus lanes with elevated boarding platforms and prepaid fares could move passengers at near-metro speeds without the cost of rail. Jakarta's version was designed by PT Pamintori Cipta, a local transportation consultancy, with support from the Institute for Transportation and Development Policy, USAID, and the University of Indonesia's Center for Transportation Studies. The concept was straightforward: pour concrete barriers on existing roads to create exclusive bus lanes, build elevated shelters so passengers board at platform height, and run articulated buses on compressed natural gas. The first corridor followed Jalan Sudirman and Jalan Thamrin, the central north-south axis of the city, running 12.9 kilometers through some of Jakarta's most congested traffic. Within its first year, it carried 14.9 million passengers -- roughly 42,000 per day.
Expansion came in waves. Corridors 2 and 3 opened in January 2006. Four more followed in 2007. By 2011, the system had eleven corridors, late-night AMARI services running past midnight, and feeder routes threading into neighborhoods the trunk lines could not reach. Corridor 13, which opened in August 2017, was the system's first elevated route, running on a dedicated overpass above street-level traffic -- a tacit admission that even dedicated bus lanes are vulnerable to the motorcycles and cars that routinely invade them. The system now stretches 251.2 kilometers, making it the longest BRT network in the world. Beyond the fourteen main corridors, TransJakarta operates seventeen cross-corridor BRT routes, fifty-seven non-BRT feeder routes, ninety-six Mikrotrans micro-bus routes, and a free double-decker tourist service called Bus Wisata. The fare remains a flat 3,500 rupiah per trip.
Between 2011 and 2015, ridership stagnated. Private vehicles kept invading the bus lanes, travel times increased, and aging buses broke down with discouraging regularity. A depot maintenance backlog and compressed-natural-gas fuel problems -- buses consuming nearly twice the fuel specified -- compounded the frustration. Then the numbers began climbing again. New feeder routes, the integration of informal angkot minibuses into the Mikrotrans network, and bus fleet replacements reversed the decline. By 2018, the system was carrying 730,000 passengers daily, up from 331,000 three years earlier. On February 4, 2020, TransJakarta crossed the one-million-rider mark for the first time. COVID-19 briefly collapsed ridership, but by June 2023 the system had recovered and passed the million mark again. The annual average in 2024 exceeded one million daily riders, making TransJakarta one of the highest-volume BRT systems on the planet.
TransJakarta has made deliberate efforts to serve populations that public transit systems often neglect. In April 2016, women-only buses painted pink were introduced on Corridor 1, staffed entirely by female drivers and onboard officers -- a response to sexual harassment reports on overcrowded buses. The system aims to recruit women for thirty percent of its driver positions. The TJ Card, introduced in 2018, provides free rides for seniors over sixty, disabled passengers, low-income households, teachers, mosque caretakers, and residents of the remote Thousand Islands Regency. Royaltrans, a premium service launched for satellite-city commuters, offers guaranteed seating, Wi-Fi, USB charging, and onboard entertainment -- no standing allowed. Disabled-friendly buses serve selected routes, with ramps at stations designed for wheelchair access, though the long slopes of older elevated walkways remain a complaint.
The system's future is electric. TransJakarta began testing battery-powered buses on the Bundaran Senayan-to-Monas route in September 2019 and has committed to converting fifty percent of its fleet to electric by 2027, with full electrification by 2030. Seventeen transit-oriented development hubs are under construction to knit TransJakarta together with the MRT, the LRT, the commuter rail, and the airport rail link. The most ambitious is the Dukuh Atas hub, which will integrate seven transport systems under one roof. Station revitalization, launched in 2022, is replacing the old aluminum-and-glass shelters with open-air concrete designs and adding restrooms, prayer rooms, and commercial spaces. The transformation is not smooth -- the closure of the critical Harmoni interchange for MRT construction in 2023 forced painful rerouting that tested rider patience. But the concrete barriers that seemed like a stopgap in 2004 have proven more durable than anyone expected. TransJakarta was supposed to hold the city together until the subway arrived. Two decades on, it has become the backbone of Jakarta's transit network, and the subway is learning to integrate with it rather than replace it.
TransJakarta's corridors span the greater Jakarta metropolitan area, centered approximately at 6.2S, 106.85E. From altitude, the dedicated bus lanes are visible as narrow corridors separated by concrete barriers along major thoroughfares, particularly Jalan Sudirman and Jalan Thamrin running north-south through central Jakarta. The elevated Corridor 13 route is visible as a raised guideway in the western part of the city. Soekarno-Hatta International Airport (WIII) lies approximately 20 km northwest. Halim Perdanakusuma Airport (WIHH) is about 12 km southeast.
