Analysis of Potential Mass Public Transport Choice Using Geographic Information System (Case Study: Commuter Line Jakarta – Bogor)

Abstract

Mode choice by travellers is carried out with several considerations. The interesting point is, some public transport users have their private vehicles. No research has described how many travellers can choose the mode and how significant their shift is to mass public transportation. The aim of research was carried out by analysing the potential for selecting mass public transportation by considering the socio-demographic, economic and vehicle ownership characteristics with the variable distance, time and travel costs based on user preferences. According to the special condition, mode choice by rail-based transit mode is called KRL commuter line, bus and private vehicle at Jakarta – Bogor Corridor become research location. Research method of mode choice probability has been developed using Multinomial Logit Model (MLM) by transport cost, time travel and distance variable. A graphical descriptive approach method based on an equation model will then overlay the site to get the results of mode selection pattern using Geographical Information System (GIS). The application of the Transit-Oriented Development (TOD) concept will be more effective if there is a transit-based mass transportation mode such as Rail-based Commuter Line (KRL) as an option, besides travellers also having private vehicles. The Result of this research is described by transport cost, travel distance, and time travel based on the revealed preference survey by 324 respondents. 50% of private car travellers are influenced by trip distance, but probability decreases if time travel increases and they switch to public transport. Users consider choosing a commuter line if the walk distance to the station is about 200 meters. On the other side, increase transport costs makes some travellers choose bus mode.
