Traffic crashes have been a major cause of death or injury across the earth.  There number of people dying had been increasing from 2015 to 2019 by an average of 27%. Red Light Camera Systems (RLCS) were thus employed by United States government to help reduce major safety problems at urban and rural intersections. The introduction of the technology permits the police to remotely monitor and apply traffic signals; they may however be deter drivers knowingly engage in red light running. According to Cohn, Kakar, Perkins, Steinbach, & Edwards (2020), RLCS are very effective at reducing crashes, red light violations and other criminal offenses due to its accuracy and efficiency caused by its automatic nature.

Operational Manuals

RLCS use high level cameras to perform its functions. The most employed camera technologies apply film-based inductive loop and cameras to detect vehicles. This data received by the cameras maybe be downloaded and used for microwave or leased telephones.

A red light camera consists of components such as camera unit. Camera unit requires additional lighting for recording of images or videos. It captures key things like drivers or license plate. Video detection which is another component, involves installation of pairs of inductive loops near the intersection at an appropriate place for indication of an occurred violation. These systems are also fitted with communications link stationed at the intersection channels where processing of violations data occurs. (Shaaban & Pande,  2018).

Red Light Camera Statistics

According to a systemic study done by (Cohn, Kakar, Perkins, Steinbach, & Edwards, 2020), RLCS has significantly reduced crash outcomes. However, crash outcomes vary with the type of crash; there is a 20% total injury crash decrease, right angle crash decreased by 24% and 29% decrease in right angle injury crashed. On the opposite, however, rear end crashed increased significantly by 19%. Generally crashed reduced by the implementation of RLCS.

How RLCS works

While such systems may look sophisticated as they rely on complex systems, their functions falls back to three simple things like sensor trigger, camera and a computer. The technologies are able to detect when a motorist have moved past a point it should not have (Goldenbeld & Daniels, 2019).

On a violation event, the trigger technology is aroused and it takes a picture or video including its license plate of the flouting motorist, mapped by the induction loop following the turning red of traffic light. Sometimes the picture of the driver is also taken. Once a violation occurs, the system generates a ticket and send it to the owner of the vehicle, alternatively, an officer may review it and judge if an error occurred. Grave mistakes my make the driver loose points.

Camera Systems Examples

Working systems is easily detected by due to its color, conspicuous position and lights it emits. These systems are able to do much more than a non-working systems. They can capture images of the vehicles, place systems, perform cleaning from attacks, store and record violations data, prepare emails, answer telephone enquiries, identify vehicle registered owner, prepare monthly progress reports.


The new technology has had impacts on almost all motorists. As a criminal justice student, these kind of new developments motivate and enables ability to do more at different times although it came at a cost of others’ jobs. These technology has improved crashes and deaths making it a suitable thing to move forward with. However, technology is better with someone’s privacy although it takes more, unless manipulated, personal data is safer. This kind of application has negatively impacted implementation of state laws. The technology is not able to monitor non-significant situations that are pardonable. Lastly, the technology is a new likely to see more advancements such as speed of processing data, reduction of end crashed.
