Implementing low carbon public transport in Jakarta


TransJakarta, Jakarta’s Bus Rapid Transit (BRT) system, currently carries 330,000 passengers per day. However many potential riders are still forced to use less fuel-efficient means of transport such as private cars, motorcycles and taxis because there is no public alternative available close by. Nevertheless, BRT ridership could be expanded significantly through the introduction of ‘trunk/feeder’ and feeder services to TransJakarta, in a package with optimization and improvements of the operational system, physical design in the trunk system and the supply network for compressed natural gas (CNG).

Some feeder routes have been identified with huge potential to maximise ridership, increase shifting from private motor vehicle as well as boost private investment. However many of the specifics of how these services will interact with the trunk system and how the use of CNG buses can be expanded were still to be addressed at the time of the project.



To improve TransJakarta services by introducing ‘trunk/feeder’ and feeder services and related modifications to the existing trunk system with the technical specifications for CNG buses and the implementation of one pilot trunk/feeder route with CNG buses.

Main Activities

  • Capture and model the travel patterns of newly created demand from the proposed feeder service
  • Develop detailed, site-specific proposals for physical and operational design modifications to the existing system required to cope with the increased demand
  • Develop technical specifications for trunk/feeder buses
  • Implement at least one trunk/feeder route as a pilot project, using CNG wherever possible.
  • Create roll-out plan to introduce the remaining feeder and trunk/feeder routes.

Expected Impact

  • Increased BRT ridership of 500,000 passengers per day or more, without worsening bottlenecks at transfer points and terminals
  • Long-term target of 1,200,000 per day once all feeder and trunk/feeder routes are implemented
  • Fuel savings of 130 million litres petrol and 35 million litres diesel annually, from passenger shifting to public transport and fuel conversion from diesel to CNG.
  • Reduction of 146,055 tonnes of CO2 by 2013.  Increased reductions over time, with a total 1,870,593 tonnes reduction over 10 years
  • Minimising the need for operating subsidies for Public Transport once all routes are operational
  • Leverage investment of over $US 40 million per year in cleaner buses and new infrastructure
