India has been experiencing an alarming rise in pedestrian deaths and injuries. Automated traffic enforcement is, therefore, the need of the hour as it can effectively reduce such untoward incidents. Radar based system can play a key role in traffic monitoring. Over the years, it has established itself as an excellent technical solution in the global transportation sector. Currently, the use of radar-based speed enforcement cameras for congestion management and speed enforcement is also gaining traction in India.
What are Radar-based Speed Violation Detection Cameras?
Radar-based speed violation detection cameras or traffic enforcement cameras use real-time 4D imaging radar-based systems that are crucial for preventing traffic fatalities caused by reckless drivers. Speed Violation Detection systems use such cameras based on radar that are changing the way people drive on roads and highways. These systems leverage radar technology to collect relevant information from the images of traffic offenders. Based on their application, speed enforcement cameras are also known by other names, such as road safety cameras, photo radar, or red light cameras.
Radar-based speed enforcement cameras with 4D imaging are powered by HD technology. These devices are exclusively developed to assess speed, as well as the direction and range of driving. These can also measure the vertical/horizontal angle, shadows, radial speed, as well as other characteristics of different static and moving targets.
Uses of Radar-based speed enforcement cameras
Radar technology has numerous applications in transportation. This technology helps predict congestion and can also reroute traffic in real-time. To ensure smooth movement of traffic, red light patterns and timing can also be changed in real-time using this technology. Research in past has highlighted the relationship between speeding and increased frequency in severity of traffic crashes. Evidence exist suggesting that speed camera operations can be an effective tool for law enforcement authorities for reducing such mishaps. They can track and take pictures of speeding vehicles, besides taking proper action against the traffic violators. Last but not the least, if the maximum speed exceeds the legal limits, a challan is issued to the offender.
Useful Features of Radar-based Speed Enforcement Cameras
Radar-based speed detection cameras have a user-friendly interface (GUI). These systems are easy to use, and a single system can cover up to four lanes. Some of these cameras can also detect several automobiles in various lanes and work in all-weather situations. These speed enforcement devices can also be used for monitoring objects within a certain range or for providing information such as vehicle density, vehicle count, categorization, queue duration, and so on.
he major characteristic of the Radar-based Speed Violation Detection System used by the cameras, is that it is easy to maintain. This highly scalable system can operate under any climate conditions, including rain, fog, dust, cloud, darkness, and so on, without requiring any cleaning. The system is known for its precision, as it can easily identify and distinguish between shadows and a motorist or vehicle. It also has the potential to identify moving and halted vehicles seamlessly. Additionally, it can also track drivers who text while driving, putting their lives as well as the lives of others in jeopardy.
How does it Work?
Radar-based speed enforcement cameras come with speed detection sensors. They consist of 4D radar, an ANPR camera or lane video recorder, an IR Illuminator, a central server and a communication network. The ANPR camera is used for reading number plates and collecting visual evidence accurately. In simple words, while the radar measures speed, lane video cameras track the license plate of the violating vehicle. The integrated radar sensor and cameras then send the collected data to the Local Central Processor for live streaming of real-time feeds and traffic violations, and also for streamlining vehicular traffic.
The system is further driven by AI technology, which helps estimate traffic congestion and modifies flow patterns through red light management. Radar Detection of Speed Violations Cameras can evaluate speed based on differences in radio wave frequency. It can compute an actual speed based on two reference points. Additionally, information about stolen, listed, or missing vehicles, can also be generated using this system.
Considering the potential of automated enforcement systems for reducing traffic crashes and fatalities, speed enforcement authorities nowadays rely on such systems. Radar-based speed enforcement cameras have become indispensable in modern times for enforcing speed restrictions on roads and highways. Such technologically advanced devices not only improve highway safety by slowing down vehicles, but also reduce traffic congestion and make a significant contribution to urban mobility safety.
