| Abstract | A joint effort of Diesel Kiki Co., Ltd. and Navigation Technologies Corp. has now (March 1990) succeeded in building and demonstrating a working prototype in-vehicle Route Guidance System (RGS) called NAVMATE*, which is now being tested in the San Francisco Bay Area. The NAVMATE RGS is a completely self-contained hardware / software / database system which incorporates the following major subsystems: ¿ Path Planning - Generates optimum routes in the road network, between the vehicle's present location (or a specified origin) and a specified destination, using a modified A* algorithm ¿ Vehicle Positioning - Determines the location of the vehicle as it travels, within very tight tolerances, using map matched dead reckoning ¿ Route Guidance - Presents real-time instructions to the driver for following the generated route This self-contained RGS contrasts sharply with some systems now being tested and marketed in Europe which employ centrally controlled traffic management infrastructures to provide approximate driving directions to equipped vehicles via two-way infrared beacons. This paper presents: (1) a functional and operational overview of an RGS from the viewpoint of the user (driver), (2) describes NAVMATE in terms of its principal hardware and software subsystems, and (3) describes NAVMATE characteristics and performance including current testing activities and their preliminary results. |

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.
