| Abstract | Current proposals of automated traffic monitoring systems for highways require high investment in terms of installation and maintenance, especially because these systems rely on a central element which is responsible for inferring and disseminating the traffic conditions. This paper presents DTraMS (Decentralized Traffic Monitoring System), a system that monitors and disseminates traffic conditions using a decentralized infrastructure. On board units and road side units do not necessarily need to be interconnected, nor connected to a central computer. These elements exchange information to update their tables that describe the traffic conditions of each route section. Vehicles serve as data mules that disseminate the information, whereas road side units store and combine the information received from them. To validate DTraMS, a prototype was implemented using IEEE 802.11b/g and experiments were performed on the campus of Federal University of Rio de Janeiro. The comparison of the results obtained with DTraMS and data obtained with a GPS shows that DTraMS is accurate in detecting both the position of the vehicle and on estimating the road condition. |

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.
