This study assesses the potential passenger preference of the High-Speed Train infrastructure, which connects Jakarta - Bandung. The study aims to understand the potential HST passenger travel characteristics, which is important in predicting the HST demand. This study conducts a roadside interview using a stated preference methodology for several transport modes passenger serving Jakarta-Bandung, namely; private vehicle, train, intercity bus and paratransit. Moreover, the study extends in observing the short trip passenger preference. The analysis defines that the preferred fares are 300.000 (20 USD), which is increased compared to 2016 studies. The forecasting results of the demand for fast trains based on the probability of modal transfers amounted to 54,764 passengers per day with details of the number of trips Jakarta-Bandung was 27,005 while the Bandung-Jakarta trip was 27,759. The results for a significant difference between the total daily trips of Bandung-Jakarta and Jakarta-Bandung have already been seen since the initial statistical analysis where according to survey data, people who travelled Bandung-Jakarta were more elastic compared to Jakarta-Bandung trips. This finding shows clearly that the passenger traffic vehicle capitulates with the current road traffic highway conditions. Note that they are more uncertainty in condition on road traffic in comparison to the railway passenger. In more details, sensitivity analysis indicates that the passenger from Jakarta is more comfortable to shift using the HST compared to the passenger from Bandung. There is an indication that the Jakarta people have a higher value of time as they have a higher preference to shift toward faster transport mode compared to Bandung people. This information is also useful for operation policy, including ticketing differentiation based on the travel time period and travel origin-destination.
