Peltzman Effect
Risk compensation is a theory which suggests that people typically adjust their behavior in response to perceived levels of risk, becoming more careful where they sense greater risk and less careful if they feel more protected. Although usually small in comparison to the fundamental benefits of safety interventions, it may result in a lower net benefit than expected or even higher risks. "Behavioural adaptation generally does not eliminate the safety gains from programmes, but tends to reduce the size of the expected effects" By way of example, it has been observed that motorists drove closer to the vehicle in front when the vehicles were fitted with anti-lock brakes. There is also evidence that the risk compensation phenomenon could explain the failure of condom distribution programs to reverse HIV prevalence and that condoms may foster disinhibition, with people engaging in risky sex both with and without condoms. By contrast, shared space is an urban street design method wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen's University At Kingston
Queen's University at Kingston, commonly known as Queen's University or simply Queen's, is a public research university in Kingston, Ontario, Canada. Queen's holds more than of land throughout Ontario and owns Herstmonceux Castle in East Sussex, England. Queen's is organized into eight faculties and schools. The Church of Scotland established Queen's College in October 1841 via a royal charter from Queen Victoria. The first classes, intended to prepare students for the ministry, were held 7 March 1842 with 13 students and two professors. In 1869, Queen's was the first Canadian university west of the Maritime provinces to admit women. In 1883, a women's college for medical education affiliated with Queen's University was established after male staff and students reacted with hostility to the admission of women to the university's medical classes. In 1912, Queen's ended its affiliation with the Presbyterian Church, and adopted its present name. During the mid-20th century, the u ...

Run-off-road Collision
A run-off-road collision (or roadway departure) is a US term for a type of single-vehicle collision that occurs when a vehicle leaves the roadway. Causes and consequences Contributing factors can include: * loss of control due to excessive or inappropriate speed * distraction * misjudging a curve * attempting to avoid colliding with another road user or an animal. If the vehicle strikes a fixed object (an object that will move very little when struck, such as a tree, bridge structure or utility pole) or rolls over, the crash is likely to result in injuries or fatalities. 2005 statistics from the US show that run-off-road crashes resulted in 31% of fatal crashes, but were only 16% of all crashes. Run-off-road collisions where the vehicle is sliding or spinning and runs broadside into a fixed obstacle are particularly dangerous since the vehicle doors and sides provide less protection to occupants than the front of the car. Target fixation is an issue for drivers, causing them t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple-vehicle Collision
A multiple vehicle collision (colloquially known as a pile-up, multi-car collision, multi-vehicle collision, or simply a multi) is a road traffic collision involving many vehicles. Generally occurring on high-capacity and high-speed routes such as freeways, they are one of the deadliest forms of traffic collisions. The most disastrous pileups have involved more than a hundred vehicles. Terminology A chain collision can be defined as "an accident involving 3 or more vehicles in which one vehicle has only rear impact damage (i.e., the "lead" vehicle); one vehicle has only frontal damage; and all other vehicles have frontal and rear impact damage (these are the "middle" vehicles)".Report No DOT HS 807 076, THE EFFECTIVENESS OF CENTER HIGH MOUNTED STOP LAMPS, A PRELIMINARY EVALUATION, March 1987, Charles J .

Insurance Institute For Highway Safety
The Insurance Institute for Highway Safety (IIHS) is a U.S. nonprofit organization funded by auto insurance companies, established in 1959 and headquartered in Arlington, Virginia. It works to reduce the number of motor vehicle traffic collisions, and the rate of injuries and amount of property damage in the crashes that still occur. It carries out research and produces ratings for popular passenger vehicles as well as for certain consumer products such as child car booster seats. It also conducts research on road design and traffic regulations, and has been involved in promoting policy decisions. Frontal crash tests The IIHS evaluates six individual categories, assigning each a "Good", "Acceptable", "Marginal", or "Poor" rating before determining the vehicle's overall frontal impact rating. Moderate overlap frontal test The moderate overlap test (formerly frontal offset test), introduced in January 1995, differs from that of the U.S. government's National Highway Traffic ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Antilock Braking System
An anti-lock braking system (ABS) is a automobile safety, safety anti-Skid (automobile), skid Brake, braking system used on aircraft and on land motor vehicle, vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining traction (engineering), tractive contact with the road surface and allowing the driver to maintain more control over the vehicle. ABS is an automated system that uses the principles of threshold braking and cadence braking, techniques which were once practiced by skillful drivers before ABS was widespread. ABS operates at a much faster rate and more effectively than most drivers could manage. Although ABS generally offers improved vehicle control and decreases stopping distances on dry and some slippery surfaces, on loose gravel or snow-covered surfaces ABS may significantly increase braking distance, while still improving steering control. Since ABS was introduced in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxicab
A taxi, also known as a taxicab or simply a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice. This differs from public transport where the pick-up and drop-off locations are decided by the service provider, not by the customers, although demand responsive transport and share taxis provide a hybrid bus/taxi mode. There are four distinct forms of taxicab, which can be identified by slightly differing terms in different countries: * Hackney carriages, also known as public hire, hailed or street taxis, licensed for hailing throughout communities * Private hire vehicles, also known as minicabs or private hire taxis, licensed for pre-booking only * Taxibuses, also come in many variations throughout the developing countries as jitneys or jeepney, operating on pre-set routes typified by multiple stops and multiple independent passenger ...
