| Abstract | Dynamic traffic flow map is one of the focuses of recent researches on ITS, but it is limited by the locations and numbers of traffic detectors. This paper presents a method for traffic flow map using the data received from the GPS mobile terminals equipped vehicles. Firstly, a vehicle real-time monitoring GPS system is given. Secondly, a map-matching method was proposed, which eliminated ineffective data by observing the vehicles status and calculated link time cost of each probe vehicle and the average speed. The equation of speed-flow relationship established by observing traffic data, especially the general one established in conditions of any traffic roads under any traffic burden conditions. Thirdly, it developed a dynamic traffic flow map arithmetic based on the results above and successfully solved the questions: data collecting, traffic barrier-free conditions processing and traffic flow map calculating. Finally, the results of simulation experiment indicate that the methods are effective and practical. It can be used as a new real time network method to control the traffic signal, which is different from the traffic signal controlled method that depends on the timer or road linear controller 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.
