| Abstract | In Intelligent Transportation System, GPS has become a major source of floating car data. GPS measurement from vehicles can be collected and be further analyzed for real-time urban traffic sensing or monitoring. However, the main challenge coming to the real-time traffic estimation system is how to scale up the system easily when the number of GPS vehicle probes grows dramatically. In this paper, a scalable real-time traffic estimation system based on distributed stream processing is developed. Differing from the traditional batch- style distributed computing techniques, e.g. MapReduce, the distributed stream processing focus on not only distributed computing but also real- time and in-memory computing such that latency is reduced. We show the system architecture, data flow and some implementation experiences for estimating urban traffic using Twitter Storm, which is the open source distributed stream processing framework. The experiment results illustrate that our system can scale well and scale up easily as the input GPS data increase. It is effective and efficient for applying stream computing in real- time traffic estimation system. |

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.
