The public transit navigator system is a system that uses a combination of public transport schedule information that changes minute-by-minute in real time, and of time tables and other fixed information, to support users’ optimum route selection of public transport systems through mobile phones or PCs. Bus-Net, a public transit navigator system, was introduced to Tottori prefecture in Japan. In the transit navigator system, the user’s search information, such as the departure place and destination, the time such information was specified and search request time, is recorded as log data. This study defines prior search time as the time difference between the search request time and the specific departure or the arrival times. And then, this study verifies factors that influence the prior search time using survival analysis. The estimation results show that prior search time is influenced by the departure place and destination, the devices utilized, the weather on the day that the searches were requested, and so on. In addition, this study shows that the estimated results enabled for the prediction of prior search time corresponding to the search situation.
