VIOLATION DETECTION & CAPTURING IN TRAFFIC LIGHT: With the growth of the urbanization, industrialization and population, there has been a tremendous growth in the traffic. With growth in traffic, there is occurrence of bundle of problems too; these problems include traffic jams, accidents and traffic rule violation at the heavy traffic signals. This in turn has an adverse effect on the economy of the country as well as the loss of lives. So problem given above will become worst in the future . In 1868, the traffic lights only installed in London and today these have installed in most cities around the world . Today traffic light violation is one of the most common and serious problem which results in the collision of millions of vehicles at the traffic light signals every year, to that manual monitoring of violations solely by human resources to checkmate offenders and violators in order to bring them to book and face the law becomes difficult. A traffic light violation occurs when a vehicle try to cross the intersection at the red traffic light .
The main types of Traffic Violations are ‘Moving Violations’ and ‘Non-Moving Traffic Violations’. Driving offences involving fatalities are ‘dangerous driving’ and ‘careless or inconsiderate driving’. A moving violation can only be issued if the car is in motion. So to give the punishment to the drivers of these vehicles, we must identify the vehicle that violates the traffic light signals.
Nowadays, Traffic control and management system is important so as to have a safer and much reliable system on roads. To control traffic violations adequately includes tracing, capturing and identifying of offender’s vehicle using advanced technology of automated device or computers with little or no manual/human aid. Some of the advanced technology which are used for traffic controls and management includes Closed Circuit Tele Vision (CCTV) cameras, also known as surveillance cameras, RFID, digital image processing and GPRS. The most common, mostly used and applied in the world today is the CCTV technology. CCTV also known as video surveillance is the use of video camera to transmit signals to a specific place, on a limited set of monitors. It differs from broadcast televisions in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP) or mesh wired or wireless links. Though video telephony is seldom called “CCTV” one where it is an important tools. These system is widely used around the world for surveillance .
VIOLATION DETECTION & CAPTURING IN TRAFFIC LIGHT: The first CCTV system was installed by siemens AG at Test stand Vii in Peenemunde Nazi Germany in 1942, for observing the launch of V-2 rockets. The earliest video surveillance system involved constant monitoring because there was no way to record and store information. The development of reel-reel media enabled the recording of surveillance footage. These system required magnetic tapes to be changed manually which was a time consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take-up reel. Due to these shortcomings, video surveillance was not widespread .
Recently CCTV technology has been enhanced with shift towards internet based products and system, and other technological development.
The surveillance cameras are installed at the main traffic junctions in the city and has been designed to complement the already existing manual mechanism to check violations. The system has a number of limitation like blurring image due to motion blur, poor image resolution because the vehicle’s plate is too far away, poor lighting, different object obscuring the plate [1,2].
