The earliest traffic sign recognition systems relied purely on pre-loaded GPS data, usually from the inbuilt satellite navigation system, to display the speed limit within the central infotainment display or instrument cluster.

Camera-based systems are constantly monitoring the road, so any changes to the speed limit or other signs are relayed almost instantly.Â

The first car to be available with a camera based TSR system which could actively read speed signs was the Opel Insignia in 2008.

The Opel system used a front-facing camera to read and temporarily display the posted speed limit within the monochrome instrument cluster. Similar technology was subsequently featured on the BMW 7 Series and Mercedes-Benz S-Class.Â

The GPS system would be used to determine the location of the car, and then cross-referenced with the relevant speed limit information stored in the car’s internal map database.   Â

Much interest in the technology of the body cameras comes from a growing problem that the United States has been having a major problem with police violence. Though some might argue that the wearing of body cameras violate privacy, in fact the use of the cameras will minimize violence, show accountability, and a human side of policing. These body cameras would help serve by providing video evidence that can be referenced and use anytime allegations are made against police officers and criminals alike. The use of these body cameras are somewhat in the evaluation and study stages, but they are quickly becoming the standard in some police departments across the United States. These cameras would not only serve to provide video evidence, but it provide accountability. The ideal policy for the cams is that they stay on and continue recording throughout police officers shifts, which would help eliminate any possibility of doing something that would not be used as evidence later on and help them evade the recording of abuse committed while on duty.

Pre-loaded maps are updatable, which may partially resolve this issue. However, these pure GPS systems would be unable to detect speed limits on variable speed signs (as commonly found on motorways) or temporary signs in the event of roadworks, for example.   Â

Once this information has been determined, it’s usually displayed as a graphic within the instrument cluster, making it easy to see what the current speed limit is.Â

Police body cameras are becoming more common in major cities around the us, and are meant to lower aggression and complaints brought upon the department's. Though the cameras are only becoming a big topic there have been many studies and debates in whether or not the cameras should be mandatory for all departments. The main and most talked about disadvantage of the cameras is the questions it raises about privacy of cops and the public. On the other hand one of the upsides are how much they will help in court cases by lowering costs and time spent. When in court the cameras can either show is it is a case of police brutality or if the cop handled the situation properly.

Police body worn cameras are recording devices used by the officers when they are on patrol, which are used for the deterrence of excessive use of force (Ariel et al. 510). The body cameras present a different frontier in the prevention of excessive force since they record the real images the police are watching. The devices are now advocated as useful tools for policing the force. The Department of Internal Affairs often relies on its footage to understand the circumstances surrounding the usage of the excessive force or a complaint on the police behavior. The tools, which are an extension of dashboard cameras, are often worn on the chest and can present the point of view of the officer as they are patrolling or tacking a criminal.

At a basic level, TSR systems are able to show the local speed limit on a particular road. Depending on the manufacturer, more advanced systems may also be able to detect other traffic signs such as ‘Stop’, ‘Give Way’, ‘Wrong Way’ and ‘No Entry’ signs and similarly display these within the instrument cluster.Â

Rather than a disparate collection of technologies, modern vehicles treat safety systems as part of an integrated whole, and TSR technology is no exception. If a car features TSR and adaptive cruise control, these will often work together seamlessly.

“The San Diego Police Department says that since officers began wearing body cameras nearly three years ago, there have been significant decreases in misconduct allegations and high-level uses of force” (Garrick 1). Along with reducing use of high level force by 16.4% (Garrick 1), body cameras can help prevent serious crime from happening or creating excessive tension. As Rachel Idowu said, “At some point, Boston could have a Ferguson [a killing at the hands of police]. Let’s put the cameras on to prevent that from happening. Rather than be reactive, let’s be proactive” (Marcelo 2). Body cameras also help maintain order by reducing the number of allegations made. According to a report done in San Diego, misconduct allegations decreased by 43.1% from 2013 to 2016 and more serious allegations went down 47.4 %. (Garrick 1). All of these factors are due to police body cameras, which help maintain order in

A forward-facing camera is connected to an onboard computer and constantly feeds it live video. The computer employs computer vision algorithms and other image recognition technologies such as Optical Character Recognition (similar to how certain software can detect text from a document) to detect the shape and content of a traffic sign.

With today’s advanced technology, police body cameras have proven to be very useful. They are crucial in putting an end to unnecessary police misconduct. In 2012, the Rialto Police Department in California implemented police body cameras and recorded the outcome. The results showed that “the number of complaints filed against officers fell by 88 percent compared with the previous 12 months. Use of force by officers fell by almost 60 percent over the same period” (Lovett). Without a doubt, police body cameras do the trick to prevent potentially dangerous situations from occurring. As William A. Farrar, the Rialto police chief once stated, “When you put a camera on a police officer, they tend to behave a little better, follow the rules a little better. And if a citizen knows the officer is wearing a camera, chances are the citizen will behave a little better.” I strongly agree with this statement because if the interaction between the officer and the citizen is being recorded, neither of the two will want to behave badly. The citizen knows that their bad behavior could result in consequences and the officer knows that their misconduct could result in punishment or even the loss of their job. The cameras record every detail that can be looked back on if there was a complaint filed against the officer that was wearing it. Clearly, police body

It is said that once a police-citizen interaction occurs, where they are both aware that they are being filmed, they will try to put on their best behavior. One of the key findings from a study published in the Journal of Experimental Criminology is that officers who did not wear body-worn cameras conducted both more arrest and more “stop and frisks” than officers who did wear the body-worn cameras (Kelsh, 2016). This indicates that officers are more cautious and risk averse when wearing body-worn cameras, this due to the fact that they thought more carefully about criminal policy and

Strictly speaking, these systems are not traffic sign recognition systems as they don’t actively look for and ‘recognise’ the surrounding speed limit and traffic signs.Â

With so many incidents occurring between law enforcement and civilians, it’s about time we have our officers wear body cameras. Law enforcement wants to use body cameras, many politicians are in favor for them, Civil-rights groups are advocating them, and communities that already have a strong police presence in their neighborhoods are requesting that the police get cameras now. With the uproar of law enforcement and the death of many black American’s, body cameras can be very useful. There is always that missing link when trying to put these horrible moments back together. Far too many times we end up with the suspect dead and only get one side of the story. With the use of body cameras, we can now get more insight on the events that happen (Boyd, 2015).

The body camera has become a popular choice amongst police departments worldwide. The situation of the scenario, and if the officer or suspect acted in the right can be determined from past footage. The cause of the body camera has been the allegations against officers for how they acted in certain situations, as well as for how the suspect acted during the callout. The effect has been officers being terminated due to lack of integrity or situational awareness, as well as officer safety. Suspects have also been convicted of false accusations against a police officer, as well as crimes presented in court, from fights, to officer involved shootings. The body worn camera has benefited both police officers and the general public.

For the past several years the push for police to wear body cameras has greatly increased. Body cameras are small video and audio recorders that can be worn by police officers to capture all encounters the officers have with citizens. Large cities and counties across the nation have been testing body cameras among several police departments to see if they can actually improve the way police and citizens interact with one another. Over the course of the past several years evidence has shown that the tests seem to be rather successful. Evidence has proved that in many cases the body cameras have made a significant impact on how some police officers deal with certain situations and behave toward citizens. Even the citizens who know they are being recorded have either changed the way they interact with the police or will not make false accusations or false complaints toward officers. In Rialto, California in 2012, the test of body cameras showed a decrease in officers using force and complaints of police brutality (BloombergView). When officers are aware that they are on camera they tend to follow the rules more. The same can be said about citizens, when the officers tell them they are being recorded, they change their behavior and sometimes begin to act more rational. Currently, the relationship between the police and citizens is rough. Citizens have trust issues with many officers, and officers are now scared that they may become targets of police hatred. Hopefully, with the

As with all camera-based active safety technology, weather remains a problem. If road signs are obscured by heavy fog or other adverse conditions, they are unlikely to be detected by the camera and won’t be displayed in the instrument cluster.Â

In February 2012, the Rialto California police department started supplying their officers with cameras they could clip on to their uniforms. At any given time, about half of their active duty officers wore these cameras. They found, in a twelve month period, that the department overall "had an 88 percent decline in the number of complaints filed against the officers". (Stross, R. 2013, April 6). They also had a 60 percent decline in the use of force by officers. They also found that officers wearing a camera were half as likely to use force as oppose to officers not wearing one. This is clear evidence that police wearing body cameras is a good

Camera-based TSR systems available today use the same fundamental principles as the Opel system, but have evolved to detect different types of traffic signs in addition to speed limits.

Certain TSR systems may get confused with time-based or moving signs, such as for school zones or on the back of buses. With school zones, the TSR system may be able to detect the speed limit, but not realise whether the posted speed limit is correct based on the time of day.

Within recent years there has been much controversy surrounding police officers and whether or not they should be wearing body cameras to document their everyday interactions with the public. While the use of body cameras may seem to invade the public or police privacy. Police-worn body cameras will be beneficial to law enforcement and civilians all over the world. Police must be equipped with body cameras to alleviate any doubt in the effectiveness of officers. Law enforcement worn body cameras would enhance the trust of the public by keeping both the officers and the citizens accountable for their actions, providing evidence, and helping protect them from false accusations, while protecting privacy

Their reliance on pre-loaded information means there’s a risk they’ll display incorrect information if a road has its speed limit changed, or if the provider of the map database (which is often a third party such as TomTom, Garmin, or HERE) originally input incorrect information.

Body Cameras The attention towards the use of body-worn cameras had risen as a result of the increase in the use of violence by police officers against civilians in the past three to four years. During this increase, media has played a large role, airing videos of the incidents and of the protest that followed such incidents. However, most of the videos shown were filmed by bystanders, and only contain fragments of the incident, which can be taken out of context (CNN, 2015). In order to provide a decrease in the use of violence and to have an efficient way to capture visual evidence, police officers should consider using body-worn cameras. Although body-worn cameras already being a well-supported topic, there are still some unanswered questions such as when should a police officer turn their body-worn camera on or off (Kelsh, 2016). However, there is already an answer to this question, although it might differ per police department, and that is a good policy on body-worn cameras. There are many policies where the police officers are encouraged to only turn on their body-worn cameras when they are among the public (Baum, 2015). Failure to do so could land police officers in a great deal of …show more content…

In some cases, the incidents were captured on camera and in other instances they weren’t. Body-worn cameras are the public’s popular choice to potentially be the solution to preventing officer-involved shootings. These devices can help by reducing police use-of-force, reducing citizen complaints against officers, increasing transparency and accountability, and increasing the likeliness of prosecution of guilty officers. There has been a lot of talk about implementing body-worn cameras in the media. In addition to the United States, there has been talk about their implementation in the United Kingdom as well. The College of Policing in England and Wales suggests that body-worn cameras will help to restore the public’s confidence in justice regarding police misconduct (Ariel, Farrar, & Sutherland, 2015). Despite these great promises, a lot more research needs to be done on body-worn

Body cameras in policing are still new, but more and more agencies are beginning to implement this technology into their line of work. At first police officers were very hesitant to wear these body cameras because they were afraid they would infringe themselves and give away their own privacy. Later, as body cameras were beginning to see more use in the work place, officers began to realize that these very own body cameras that they once thought would only cause themselves harm would actual prove to be useful in a variety of situations. Some of these situations can be citizen complaints, to even backing up an officers use of force. Body cameras can be the one sole thing that can give

In the high-tech age we live in, and where the use of smart phones can capture and record live actions and moments, many of these moments are now being captured by on-duty police officers who are using body mounted cameras to record incidents as they occur. The cameras, that these officers are utilizing, are small devices that are no more than two inches long and can be easily installed onto the officer’s glasses. The recording device is then attached to the officer’s uniform and is placed in an obscured location. The use of these body cameras are still under scrutiny but are quickly becoming standard uniform equipment in law enforcement departments throughout the United States.
