NHTSA
The National Highway Traffic Safety Administration (NHTSA ) is an agency of the U.S. federal government, part of the Department of Transportation, focused on automobile safety regulations. NHTSA is charged with writing and enforcing Federal Motor Vehicle Safety Standards (FMVSS), regulations for motor vehicle theft resistance, and fuel economy, as part of the Corporate Average Fuel Economy (CAFE) system. FMVSS 209 was the first standard to become effective on March 1, 1967. NHTSA licenses vehicle manufacturers and importers, allows or blocks the import of vehicles and safety-regulated vehicle parts, administers the vehicle identification number (VIN) system, develops the crash test dummies used in U.S. safety testing as well as the test protocols themselves, and provides vehicle insurance cost information. The agency has asserted preemptive regulatory authority over greenhouse gas emissions, but this has been disputed by state regulatory agencies such as the Califo ...

Transportation Safety In The United States
Transportation safety in the United States encompasses safety of transportation in the United States, including Traffic collision, automobile crashes, Aviation accidents and incidents, airplane crashes, Train wreck, rail crashes, and other mass transit incidents, although the most fatalities are generated by road incidents annually killing 32,479 people in 2011 to over 42,000 people in 2022. The number of deaths per passenger-mile on commercial airlines in the United States between 2000 and 2010 was about 0.2 deaths per 10 billion passenger-miles. For driving, the rate was 150 per 10 billion vehicle-miles: 750 times higher per mile than for flying in a commercial airplane. For a person who drives a million miles in a lifetime (somewhat above average) this amounts to a 1.5% chance of death. There is a considerable and growing gap between the United States and other comparable countries in terms of roadway deaths, with the United States having higher death rates. In 2014, tw ...

Seat Belts
A seat belt, also known as a safety belt or spelled seatbelt, is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic collision by reducing the force of secondary impacts with interior strike hazards, by keeping occupants positioned correctly for maximum effectiveness of the airbag (if equipped), and by preventing occupants being ejected from the vehicle in a crash or if the vehicle rolls over. When in motion, the driver and passengers are traveling at the same speed as the vehicle. If the vehicle suddenly halts or crashes, the occupants continue at the same speed the vehicle was going before it stopped. A seat belt applies an opposing force to the driver and passengers to prevent them from falling out or making contact with the interior of the car (especially preventing contact with, or going ...

Crash Test Dummy
A crash test dummy, or simply dummy, is a full-scale Anthropomorphism, anthropomorphic test device (ATD) that simulates the dimensions, weight proportions and articulation of the human body during a traffic collision. Dummies are used by researchers, automobile and aircraft manufacturers to predict the injuries a person might sustain in a crash. Modern dummies are usually instrumented to record data such as velocity of impact, crushing force, bending, folding, or torque of the body, and deceleration rates during a collision. Prior to the development of crash test dummies, automobile companies tested using human Cadaver, cadavers, animals and live volunteers. Cadavers have been used to modify different parts of a car, such as the seatbelt. This type of testing may provide more realistic test results than using a dummy, but it raises ethical dilemmas because human cadavers and animals are not able to consent to research studies. Animal testing is not prevalent today. Computational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Car Safety
Automotive safety is the study and practice of automotive design, construction, equipment and regulation to minimize the occurrence and consequences of traffic collisions involving motor vehicles. Road traffic safety more broadly includes roadway design. One of the first formal academic studies into improving motor vehicle safety was by Cornell Aeronautical Laboratory of Buffalo, New York. The main conclusion of their extensive report is the crucial importance of seat belts and padded dashboards. However, the primary vector of traffic-related deaths and injuries is the disproportionate mass and velocity of an automobile compared to that of the predominant victim, the pedestrian. According to the World Health Organization (WHO), 80% of cars sold in the world are not compliant with main safety standards. Only 40 countries have adopted the full set of the seven most important regulations for car safety. In the United States, a pedestrian is injured by a motor vehicle every 8 mi ...

Ford Explorer
The Ford Explorer is a range of Sport utility vehicle, SUVs manufactured by Ford Motor Company since the 1991 model year. The first five-door SUV produced by Ford, the Explorer, was introduced as a replacement for the three-door Ford Bronco II, Bronco II. As with the Ford Ranger, the model line derives its name from a trim package previously offered on Ford F-Series pickup trucks. As of 2020, the Explorer became the best-selling SUV in the American market. Currently in its sixth generation, the Explorer has featured a five-door wagon body style since its 1991 introduction. During the first two generations, the model line included a three-door wagon (directly replacing the Bronco II). The Ford Explorer Sport Trac is a crew-cab mid-size pickup derived from the second-generation Explorer. The fifth and sixth generations of the Explorer have been produced as the Ford Police Interceptor Utility (replacing both the Ford Crown Victoria Police Interceptor and the Ford Police Intercepto ...

Fatality Analysis Reporting System
Fatality Analysis Reporting System (FARS) was created in the United States by the National Highway Traffic Safety Administration (NHTSA) to provide an overall measure of highway safety, to help suggest solutions, and to help provide an objective basis to evaluate the effectiveness of motor vehicle safety standards and highway safety programs. FARS contains data on a census of fatal traffic crashes within the 50 states, the District of Columbia, and Puerto Rico. To be included in FARS, a crash must involve a motor vehicle traveling on a trafficway customarily open to the public and result in the death of a person (occupant of a vehicle or a non-occupant) within 30 days of the crash. FARS has been operational since 1975 and has collected information on over 989,451 motor vehicle fatalities and collects information on over 100 different coded data elements that characterizes the crash, the vehicle, and the people involved. FARS is vital to the mission of NHTSA to reduce the number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Stability Control
Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology that improves a car handling, vehicle's stability by detecting and reducing loss of Traction (engineering), traction (skid (automobile), skidding). When ESC detects loss of steering control, it automatically applies the brakes to help steer the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer. Some ESC systems also reduce engine power until control is regained. ESC does not improve a vehicle's cornering performance; instead, it helps reduce the chance of the driver losing control of the vehicle on a slippery road. According to the U.S. National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety in 2004 and 2006, one-third of fatal accidents could be ...

Audi 100
The Audi 100 and Audi 200 (and sometimes called Audi 5000 in North America) are primarily mid-size/executive cars manufactured and marketed by the Audi division of the Volkswagen Group. The car was made from 1968 to 1997 across four generations (C1–C4), with a two-door model available in the first and second generation (C1-C2), and a five-door model available in the last three generations (C2–C4).They also made an 100 Avant in the 1970s. In 1982, the third generation Audi 100 achieved a remarkably low (for its time) drag coefficient of 0.30, featuring flush greenhouse sides with unique sliding window mountings. The C2 and C3 models of the Audi 100 were marketed in North America as the Audi 5000 from 1978 to 1988, and in South Africa as the Audi 500. In 1993, the models were mildly restyled, and renamed the Audi A6 series in conjunction with a general new Audi naming scheme, until they were replaced by a new generation of A6, internally code-named C5, in 1997. The Audi 100's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Traffic And Motor Vehicle Safety Act
The National Traffic and Motor Vehicle Safety Act was enacted in the United States in 1966 to empower the federal government to set and administer new safety standards for motor vehicles and road traffic safety. The Act was the first mandatory federal safety standards for motor vehicles. The Act created the National Highway Safety Bureau (now National Highway Traffic Safety Administration). The Act was one of a number of initiatives by the government in response to increasing number of cars and associated fatalities and injuries on the road following a period when the number of people killed on the road had increased 6-fold and the number of vehicles was up 11-fold since 1925. The reduction of the rate of death attributable to motor-vehicle crashes in the United States represents the successful public health response to a great technologic advance of the 20th century—the motorization of the United States. History Systematic motor-vehicle safety efforts began during the 1960s. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unsafe At Any Speed
''Unsafe at Any Speed: The Designed-In Dangers of the American Automobile'' is a non-fiction book by consumer advocate Ralph Nader, first published in 1965. Its central theme is that car manufacturers resisted the introduction of safety features (such as seat belts), and that they were generally reluctant to spend money on improving safety. The work contains substantial references and material from industry insiders. It was a best seller in non-fiction in 1966. The book resulted in the creation of the United States Department of Transportation in 1966 and the predecessor agencies of the National Highway Traffic Safety Administration in 1970. Theme ''Unsafe at Any Speeds critique of the Chevrolet Corvair received widespread attention. It also dealt with the use of tires and tire pressure being based on comfort rather than on safety, and the automobile industry disregarding technically based criticism. A 1972 National Highway Traffic Safety Administration report disputed Nader's al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Economy In Automobiles
The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of the volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since the importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses ( wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
