| Abstract | Current and future in-vehicle personal assistant systems stand to benefit from knowledge of the level of familiarity that the driver has with different parts of the current route. Such systems could use this information to adapt driving directions to be more succinct, understandable and personalized. However accumulating evidence of familiarity by direct experience alone could take many months and still be incomplete. Instead, we propose building predictive models of driver familiarity with road networks by generalizing intelligently from a small sample of data. Inspired by psychology studies that suggest a variety of cognitive models of route familiarity in humans, we present an ensemble of familiarity models using different machine learning methods on GPS time series data collected during normal driving by a volunteer pool of 22 drivers from San Francisco Bay area. We validate the models' predictions through an extensive questionnaire administered to the subjects about route familiarity and need for directions along select routes. Our results indicate that a significant component of driver familiarity can be predicted from unobtrusively collected driving data. We conclude with a proposed approach for integrating such models with a generator of driving directions. |

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.
