Intelligent Transport Systems (ITS) is the concept for the construction of a Transport Infrastructure that involves a driven data, telecommunications network for consumers, roads and automobiles. Video Detection is most widespread used in the Intelligent Transportation System (ITS) as it plays a key role in Transportation System. Dynamic modifications of background images due to environment, lightening, shadows make it inconvenient in detecting and tracking moving vehicles from the videos. Therefore, the moving background objects, brightness variation and vehicle adhesion create several challenges in the detection of moving vehicle. To minimize the problem, automatic moving vehicle detection is discussed in this thesis. This chapter consists of background of ITS system, Moving Vehicle System, Tracking Algorithms and applications. It also discusses the problems in Vehicle Detection System, followed by the Research Objective and Thesis Organization.
