JAKARTA TRANSPORT NETWORK - PLANNING AND REGULATION PROJECT. 1: MASS TRANSIT SYSTEM PROPOSALS

This paper describes a special study undertaken to investigate future levels of travel demand in and around Jakarta, Indonesia, and to identify mass transit routes and services that could meet these needs. It was clear that buses operating in mixed traffic could not meet longer-term public transport demand, and suspected that the approved upgrading of suburban rail services in the Jabotabek area would be insufficient. To reduce the study timescale, a multimodal investigation of future travel demand was required, including the identification of appropriate mass transit systems. Previous home interview survey data were used, together with direct interview data. These data were used to calibrate a 1990 travel demand model, which was used to forecast future modal travel demands under various network assumptions. The results were used to evaluate the benefits of various mass transit proposals. Exploratory transport investment studies were also developed. Mass transit technologies were reviewed, and the following transit systems were selected: (1) heavy rail, for suburban and inter-city services; (2) 100km of light rail transit for main intra-urban corridors, including 76km of converted heavy rail; (3) 114km of busways for main intra-urban corridors and feeder routes. The new proposals are estimated to cost about US$3 billion.
