Riding the TransJakarta Bus
Evaluation of TransJakarta Bus. By Damantoro & Harya Setyaka Dillon

TransJakarta Busway accounts for 240 thousand ridership a day. While the figure is well below the standard of TransMillenio in Bogota of 1.4 million, ridership has increased by 25% since 2007. TransJakarta Busway is the largest BRT network in Asia which runs along 8 corridors of 120 KMs, serviced by 335 compressed natural gas (CNG) buses and 91 diesel buses. It is estimated that by 2008, the system had reduced carbon dioxide by 32, 310 tons per year and nitrous oxide by 386 tons per year.


Increased TransJakarta ridership and reduced passenger subsidy

Anticipating increased demand and recognizing the need to provide high quality mass transit, BLU TransJakarta has committed to expanding its infrastructure and improving service. The new corridor which was open on February 21st 2009 after missing several deadlines, was met with 11.000 enthusiastic passengers. Two more corridors are expected to start operation by the end of this year. Having grown from 13 KMs when the first corridor was launched in 2005, TransJakarta Busway is undoubtedly the fastest growing BRT network.

Albeit the network growth TransJakarta faces complaints from the passengers mostly relating to convenience, safety and speed. "Why it takes so long for the bus to come. I have been waiting more than 15 minutes here" said a pregnant passenger who was waiting in the Harmoni Central station.

The four main areas of concern are long queues for passengers to board, lack of passenger information, insufficient bus frequency and the condition of stations.
Long queuing times and insufficient bus frequency are caused by design and operational problems. Buses spend 13.3 to 30.3 percent of their travel time at traffic lights. Delays at intersections and the absence of an operational control system also leads to buses bunching, resulting in irregular intervals between buses where buses failed to arrive for a while, and then suddenly 3 to 4 buses will arrive simultaneously.

It can be concluded that expansion of the system needs to be equally complemented by strong attention to the level of service provided by the system. Only then, will TransJakarta help transform the city’s image of infamous congestion into famous, world-class example of progressive mobility for its citizens.
