Speed cameras are installed on roads to detect the vehicles that are speeding using devices like detectors connected to radar technology or sometimes road surface. Speed cameras also record when the car crosses the stop line in a red-light or when it is entering an intersection after the light turned red. A picture of the vehicle breaking the rule is taken, and the owner of the car is fined. It is also called a traffic enforcement camera.
After installing these cameras, people have become more careful with their driving due to high penalties. The cameras have reduced fatal or severe crashes to somewhat 11% to 40%. Speed camera detector UK transportation department has collected data of reduction in collisions and says over 42% of personal injuries have decreased. Wider deployment is now getting recommended due to the drastic decrease in accidents in the vicinity of the camera. Adding 1000 more cameras can save up to 200 lives per year and reduce up to 1200 more collisions to happen. The new number plate automatic recognition technology is detecting the average speed of the vehicle. This method of mass surveillance enforced by the government is increasing privacy invasion concerns for the vehicle owners.
In multi-lane situations, every lane is embedded with sensors on the surface of the road. This technology does not leave a single car by changing lanes. In the case of bus lane enforcement, the sensors on the road trigger the camera to run the number plate and record images. UK, USA, and Australia have already installed these and in fully functional condition. Anyone who enters the bus lane is penalized, and even the buses, if stopped in unwanted places, are too. The camera is mounted in an angle that it can take a picture of any vehicle in line. Apart from red-light violators, these cameras also catch texting while driving people also.
A multipurpose traffic enforcement camera comes with several other features. It includes detecting cars that violate lane occupancy requirements on congested lanes. Cameras also detect heavy vehicles that do not stick to noise pollution regulations. It is found by using compression release engine brakes. Some cameras detect vehicles that proceed through the toll-booth without paying the bill. Mobile speed cameras are also available. It does not necessarily have to be stationary to calculate speed. The calculation can be carried out with relative speed. The calibration of the speedometer of the vehicle carrying the camera has to be perfect.
Many issues arose due to the introduction of these cameras. Some countries hired private contractors to check on the over speeding detectors and paid them a commission for the number of tickets. Legal complaints were filed about this issue. Many complained that this denied the fundamental right to move freely without being under surveillance. Also, the sub-contractors overtime started exploiting their power, and this system was deemed untrustworthy and not reliable. It is also an issue when it is the owner’s liability to pay the fine no matter who is driving the car. If the owner can identify who drove it, then the driver has to pay; otherwise, it is the owner’s responsibility.
Privacy of details
If you are caught on one of these cameras, the recorded image cannot be altered or tampered. All the relevant information related to the image, including date and location, is encrypted. The image forms the necessary foundation of the case in court, along with with with an expert signed evidentiary certificates. When it comes to reliability, these cameras have varying accuracy throughout systems. Ensure this strength, accuracy, and reliability of the device should be considered.
