Red Light Violation Identification System
Smart Transport iRIDS (Intelligent Red Light Violation Identification System) is a state-of-the-art device that captures

images and videos of red light violations with the help of vehicle sensors, cameras, and controller
hardware installed at busy road intersections.

Unlike the other red light violation devices, iRIDS will provide vehicle and traffic signal in a single image.
Not only the stills, the iRIDS also given video footage of violations. A three-second video and three
progressive snapshots recorded by iRIDS will be enough to catch red light jumpers. It also helps

enforcement agencies in giving proof that could not be challenged in court.

In iRIDS, the sensor, camera and controller work in a loop configuration. The sensor will detect vehicle
presence from loops and trigger camera, which capture image of violated vehicles. It also capture image
of the number plate.

Using RTO database connectivity, the iRIDS could issue ticket with vehicle owners name and address.

Area Traffic Control System (CoSiCoSt)

Area Traffic Control Systems (ATCS) are traffic responsive systems that use data from vehicle
detectors and optimize traffic signal settings to reduce vehicle delays and stops. The system operates
in a closed loop, evaluating the real time demand and properly updating network signal timings.

C-DAC developed a Composite Signal Control Strategy (CoSiCoSt) for distributed network model that
address all typical Indian road conditions. Strategies are built into the system to guard against
network failure, power failure etc.

Major building blocks of ATCS:
Traffic Signal Controller
Vehicle Detectors
Communication Network
Application Software
Central Control Station
