Modeling the market penetration of personal public transport information system in Hong Kong

In Hong Kong, with a multi-modal transport network, about one-fifth of the general public require to make transfer during their daily travel. In order to help passengers making decisions on travel choices, the personal Public Transport Information System (PTIS) has recently been introduced in Hong Kong. This article investigates the market penetration, or the potential demand, of the proposed personal PTIS in Hong Kong. A binary logit model was calibrated to investigate how passenger demographics and trip characteristics would affect the market penetration of the personal PTIS. In the interview survey, stated preference questions were asked for obtaining a respondent's desirability of the personal PTIS. The model results suggested that a market does exist for the personal PTIS in Hong Kong with its multi-modal transit network. Number of transfers required for completing a journey, departure time, travel time, income, and mobile telephone ownership all has significant relationships with the demand of the personal PTIS. Service charge and length of delay in receiving information also highly affect the market penetration of the personal PTIS.
