| Abstract | Automatic traffic abnormality detection through visualsurveillance is one of the critical requirements for IntelligentTransportation Systems (ITS). In this paper, wepresent a novel algorithm to detect abnormal traffic eventsin crowded scenes. Our algorithm can be deployed with fewsetup steps to automatically monitor traffic status. Differentfrom other approaches, we don’t need to define region ofinterests (ROI) or tripwires nor to configure object detectionand tracking parameters. A novel object behavior descriptor- directional motion behavior descriptors are proposed.The directional motion behavior descriptors collectforeground objects’ direction and speed information from avideo sequence with normal traffic events, and then thesedescriptors are accumulated to generate a directional motionbehavior map which models the normal traffic status.During detection steps, we first extract the directional motionbehavior map from the newly observed video and thenmeasure the differences between the normal behavior mapand the new map. If new direction motion behaviors arevery different from the descriptors in the normal behaviormap, then the corresponding regions in the observed videocontain traffic abnormalities. Our proposed algorithm hasbeen tested using both synthesized and real surveillancevideos. Experimental results demonstrated that our algorithmis effective and efficient for practical real-time trafficsurveillance applications. |

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.
