Motorcycle Fatality Rate In U.S. By Year
This is a list of numbers of motorcycle deaths in U.S. by year from 1994 to 2014. United States motorcycle fatalities increased every year for 11 years after reaching a historic low of 2,116 fatalities in 1997, then increased to over 5,000 around 2008 and then plateaued in the 4 to 5 thousands range in the 2010s. In nine years motorcycle deaths more than doubled from the late 1990s to 2008. Despite providing less than 1% of miles driven, they made up 15% of traffic deaths in 2012. Since about 2004 over 4,000 people have died every year up to 2014 in motorcycle accidents, and in 2007 and 2008 deaths exceeded 5,000 per year. At the same time occupant deaths of other types of vehicles have decreased in the 21st century, so motorcycle accident deaths have become an increased share of all deaths and noted for being 26 times more deadly than cars. Operators of sport motorcycle models had a higher rate of death compared to other motorcycle types, and speeding was noted in roughly half ...

Gyroscope Wheel-text
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submerged submarine. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes can ...

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 yearly killing from 32,479 to nearly 38,680 (+%) in the last decade. 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. The U.S. government's National Center for Health Statistics reported 33,736 motor vehicle traffic deaths in 2014. This exceeded the number of firearm deaths, which was 33,599 in 2014. According to another U.S. government office, the National Highway Traffic Safety Administration (NHTSA), motor vehicle crashes ...

Crumple Zones
Crumple zones, crush zones, or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity (and consequently momentum) occurs from the impact during a collision by a controlled deformation; in recent years, it is also incorporated into trains and railcars. Crumple zones are designed to increase the time over which the total force from the change in momentum is applied to an occupant, as the average force applied to the occupants is inversely related to the time over which it is applied. The physics involved can be expressed by the equation: :F_\text\Delta t = m\Delta v where F is the force, t is the time, m is the mass, and v is the velocity of the body. In SI units, force is measured in Newtons, time in seconds, mass in kilograms, velocity in metres per second, and the resulting impulse is measured in newton seconds (N⋅s). Typically, crumple zones are located in the front part of the vehic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle And Motorcycle Dynamics
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today. Bicycles and motorcycles are both single-track vehicles and so their motions have many fundamental attributes in common and are fundamentally different from and more difficult to study than other wheeled vehicles such as dicycles, tricycles, and quadracycles. As with unicycles, bikes lack lateral stability when stationary, and under most circumstances can only remain upright when moving forward. Experimentation and mathematical analysis Analysis is the branch of mathematics dealing with continuous functions, limit (mathematics), limits, and related theories, such as Der ...

Lane Splitting
Lane splitting is riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. It is sometimes called whitelining, or stripe-riding. This allows riders to save time, bypassing traffic congestion, and may also be safer than stopping behind stationary vehicles. Filtering or filtering forward describes moving through traffic that is stopped, such as at a red traffic light. In the developing world In population-dense and traffic-congested urban areas, particularly in the developing world, the space between larger vehicles is filled with a wide variety of different kinds of two-wheeled vehicles, as well as pedestrians, and many other human or animal powered conveyances. In places such as Bangkok, Thailand and in Indonesia, the ability of motorcycles to take advantage of the space between cars has led to the growth of a motorcycle taxi industry. In Indonesia, the motorcycle is the most common type of vehicle. Unlike typical de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurt Report
The Hurt Report, officially ''Motorcycle Accident Cause Factors and Identification of Countermeasures'', was a motorcycle safety study conducted in the United States, initiated in 1976 and published in 1981. The report is named after its primary author, Professor Harry Hurt. Noted motorcycle journalist David L. Hough described the Hurt Report as "the most comprehensive motorcycle safety study of the 20th century." The study was initiated by the Department of Transportation's National Highway Traffic Safety Administration, which contracted with the University of Southern California Traffic Safety Center — the work was ultimately conducted by USC professor Harry Hurt. The Hurt Report findings significantly advanced the state of knowledge of the causes of motorcycle accidents, in particular pointing out the widespread problem of car drivers failing to see an approaching motorcycle and precipitating a crash by violating the motorcyclist's right-of-way. The study also provided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorcycle Safety
Motorcycle safety is the study of the risks and dangers of motorcycling, and the approaches to mitigate that risk, focusing on motorcycle design, road design and traffic rules, rider training, and the cultural attitudes of motorcyclists and other road users. Riding motorcycles on public roads carries several times the risk of riding in cars, which themselves are more risky than public conveyances like buses and trains. The human factors of motorcycle crashes are roughly equal between rider behavior and the actions of drivers sharing the roads. Technological changes, especially in the latter half of the 20th century, have made significant improvements in motorcycle safety. Serious research into motorcycle safety began in the US with the Hurt Report in 1981, followed by major studies in Europe and others. The main result of this research has been a greater emphasis on rider training and stricter licensing requirements. The US military recognized the need for their own focused motorcyc ...

Speed Wobble
Wobble, shimmy, tank-slapper, speed wobble, and even death wobble are all words and phrases used to describe a quick (4–10 Hz) oscillation of primarily just the steerable wheel(s) of a vehicle. Initially, the rest of the vehicle remains mostly unaffected, until translated into a vehicle yaw oscillation of increasing amplitude producing loss of control. Vehicles that can experience this oscillation include motorcycles and bicycles, skateboards, and, in theory, any vehicle with a single steering pivot point and a sufficient amount of freedom of the steered wheel, including that which exists on some light aircraft with tricycle gear where instability can occur at speeds of less than ; this does not include most automobiles. The initial instability occurs mostly at high speed and is similar to that experienced by shopping cart wheels and aircraft landing gear. Theory Sustained oscillation has two necessary components: an underdamped second- or higher-order system and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowsider
The lowsider or lowside is a type of motorcycle or bicycle crash usually occurring in a turn. It is caused when either the front or rear wheel slides out as a result of either too much braking into the corner, too much acceleration through or out of the corner, or too much speed carried into or through the corner for the available grip. It may also be caused by unexpected slippery or loose material (such as oil, water, dirt or gravel) on the road surface. In the United Kingdom, Canada, New Zealand and Australia it is referred to as a "lowside" rather than a "lowsider". Causes of lowsider crashes All horizontal forces occurring between the motorcycle and the road (such as accelerating, decelerating and steering) are transmitted by friction in the contact patches. There is a limited amount of force each contact patch can transmit before the tire begins to slide. Typically, the maximum force once sliding is slightly less than before sliding."Tire and Vehicle Dynamics", Hans B Pacejk ...
