| Abstract | In the daily life, people often repeat regular routes in certain periods. Predicting personal future routes using this information helps to achieve many goals, including improving the quality of intelligent transportation systems (ITSs) and location-based services (LBSs) for individuals. In this paper, a novel system is developed to predict the personal future routes based on the continuous route patterns extracted in advance. The proposed approach predicts a person's future route through the use of a probabilistic tree model built from his / her route patterns. The route patterns are extracted from personal history of movement using a new mining algorithm, continuous route pattern mining (CRPM), which based on PrefixSpan. Furthermore, the separated system architecture guarantees the safety of personal privacy while greatly reducing the computational load on mobile devices. An evaluation using a corpus of real routes from 17 persons demonstrates the effectiveness of the system. Using only a month recorded trips data, our system can get an average correct rate of about 74.3% in one step predicting. In route prediction, the average Levenshtein distance between the real trips and predicting results produced by our system is about 30% shorter than that produced by the basic Markov method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
