Speed cameras turn up trumps on toll

History Dutch company Gatsometer BV, founded by the 1950s rally driver Maurice Gatsonides, invented the first road-rule enforcement cameras. Gatsonides wished to better monitor his speed around the corners of a race track and came up with the device in order to improve his time around the circuit. The company developed the first radar for use with road traffic, and is the world's largest supplier of speed camera systems. Because of this, in some countries all makes of speed cameras are sometimes generically referred to as "Gatsos".  The first systems introduced in the late 1960s used film cameras to take their pictures. From the late 1990s, digital cameras began to be introduced. Digital cameras can be fitted with a modem or other electronic interface to transfer images to a central processing location automatically, so they have advantages over film cameras in speed of issuing fines, and operational monitoring. However, film-based systems still provide superior image quality in the variety of lighting conditions encountered on roads, do not suffer from pixelation, and are required by courts in some jurisdictions (due to the ease with which digital images may be modified). New film-based systems are still being sold, but digital pictures are providing the greater versatility (although not yet superior image quality) due to ease of data transmission. Verification and system testing In the UK, every speed camera must be calibrated and certified before the images from it are acceptable to the court, including the cameras used in police vehicles. Several speeding prosecutions have failed in the UK due to out of date calibration certificates. The pictures taken by road-rule enforcement cameras may need to be viewed by a person, and judged to be satisfactory or not, before any infringement notice or ticket is issued. This step is known as verification, and may be a legal requirement in specific jurisdictions. Verifiers typically must check some or all of the following depending on the jurisdiction: 1. that there is no sign of interference with the vehicle detector by objects other than the alleged speeding vehicle 2. that the licence plate is unambiguously readable according to a legal standard 3. that the make and model of vehicle matches that recorded by the licensing authority for the number plate 4. that the appearance of the driver in the images is adequate in some way - for example, that it matches the picture on the driving licence of the vehicle's registered owner. Generally, cameras must undergo approval testing and operational testing to ensure that they function adequately. In the United States, it is common for all installation, operation, and verification procedures to be carried out by private companies that in some states receive payment based on the number of infringements they issue, and often under no testing regime whatsoever. How the death rate has fallen Road traffic collisions are an important cause of death and disability worldwide. Every year around the world 1.2 million people are killed and up to 50 million are injured or disabled as a result of road traffic collisions.1 Morbidity from road traffic collisions is expected to increase in future years, and it is estimated that road traffic collisions will move from ninth to third place in the global burden of disease ranking, as measured in disability adjusted life years. Measures to reduce traffic speed are considered essential to reducing casualties on the road. Speed cameras are increasingly used to help to reduce traffic speeds in the belief that this will reduce road traffic collisions and casualties, and an expansion in the use of speed cameras is under way in many countries. Published research consistently shows the effectiveness of speed cameras in preventing road traffic collisions and injuries. Actuality in china In recent years, china is enlarging the infrastructure investment above all the highway construction. Management of the modern traffic demand is more and more pressing. The Ministry of Public Security has put forward: Speeding capture system is being required. CCD speed camera will capture the speeding goal, then it will simulate the digital image through the data acquisition system and sent to a PC Image signal processing, providing the evidence to the law enforcement departments Due to the Beijing 2008 Olympic Games, China's road construction are unprecedented prosperity and development. At the same time, speed camera industry in China will also develop thriving.
