Impact of Introducing Medium-Speed Rail on Low-Cost Carrier Air Transport Demand for Jakarta-Semarang

Population growth in Jabodetabek (Jakarta, Bogor, Depok, Tangerang, and Bekasi) and Kedungsepur (Kendal, Demak, Ungaran, Semarang, Salatiga, and Purwodadi) Area has led to the increase of travel demand within and between these two areas. The population of the two areas reaches 33.7 million people or about 25% of the population on java island. The increase in travel demand between these two areas needs to be accommodated by a complementary transport mode that connects them, one of the options is to build a medium-speel railway network. The study analyses the effect of mediumspeed railway operation on low-cost carrier air passenger travel demands of the Jakarta - Semarang route including influential travel attributes through literature review and systematic. Stated preference is used for data collection and the logit binomial model has used the modeling method. Various independent variables, such as monthly income, age, gender, occupation, level of education, trip purpose, and travel mode to airport, are considered in the model development. The result shows that monthly income and transport mode to access the airport has a significant influence on passenger mode choice. Further and in-depth research is needed, including certainty of train speed so that it can compete with airplane travel time, other attributes that affect the choices offered and reflect the needs of service users so that the resulting model is closer to reality and other behaviors will be different when this model is used for passenger full-service carrier aircraft.
