摘要
En 中文
Human tracking and prediction are pervasive nowadays. It is possible to integrate multi-source human tracking data and location based social media data, which includes spatial data, temporal data, and textual data, to make human-mobility prediction and over-crowded station detection, and then to plan convenient bus/subway routes for passengers. This study is useful in many real applications, including convenient travel route recommendation and location based services in general. We face two challenges in this study: (1) how to use multi-source human tracking data to model probabilistic transfer cost between different bus/subway lines practically, and (2) how to compute convenient bus/subway routes efficiently. To overcome these challenges, we define a set of probabilistic spatial metrics and propose a travel-time threshold and a transfer-cost threshold convenient route planning queries. A series of optimization techniques are developed to enhance the query efficiency. We also conduct extensive experiments to verify the performance of the proposed algorithms. (C) 2017 Elsevier B.V.
