Road Safety
Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, horse riders, and passengers of on-road public transport (mainly buses and trams). Best practices in modern road safety strategy: As sustainable solutions for classes of road safety have not been identified, particularly low-traffic rural and remote roads, a hierarchy of control should be applied, similar to classifications used to improve occupational safety and health. At the highest level is sustainable prevention of serious injury and death crashes, with sustainable requiring all key result areas to be considered. At the second level is real-time risk reduction, which involves providing users at severe risk with a specific warning to enable them to take mitigating action. The third level is about reducing the crash risk which involves applying the road-design standards a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Killed Or Seriously Injured
Killed or seriously injured (KSI) is a standard metric for safety policy, particularly in transportation and road safety. History ISO 39001 considers a serious injury as having an impact on the body or on the capacity of an individual. Definition United Kingdom definitions *Killed: The usual international definition, as adopted by the Vienna Convention in 1968 is 'A human casualty who dies within 30 days after the collision due to injuries received in the crash'. *Serious injury: The definition is less clear-cut and may vary more over time and in different places. The UK definition covers injury resulting in a person being detained in hospital as an in-patient, in addition all injuries causing: fractures, concussion, internal injuries, crushings, burns (excluding friction burns), severe cuts, severe general shock which require medical treatment even if this does not result in a stay in hospital as an in-patient. *Slight injury: Sprain (including neck whiplash injury), bruising o ...

Litter (vehicle)
The litter is a class of wheelless vehicles, a type of human-powered transport, for the transport of people. Smaller litters may take the form of open chairs or beds carried by two or more carriers, some being enclosed for protection from the elements. Larger litters, for example those of the Chinese emperors, may resemble small rooms upon a platform borne upon the shoulders of a dozen or more people. To most efficiently carry a litter, porters either place the carrying poles directly upon their shoulders or use a yoke to transfer the load from the carrying poles to the shoulders. Definitions A simple litter consists of a sling attached along its length to poles or stretched inside a frame. The poles or frame are carried by porters in front and behind. Such simple litters are common on battlefields and emergency situations, where terrain prohibits wheeled vehicles from carrying away the dead and wounded. Litters can also be created quickly by the lashing of poles to a chair. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Roads
Roman roads ( la, viae Romanae ; singular: ; meaning "Roman way") were physical infrastructure vital to the maintenance and development of the Roman state, and were built from about 300 BC through the expansion and consolidation of the Roman Republic and the Roman Empire. They provided efficient means for the overland movement of armies, officials, civilians, inland carriage of official communications, and trade goods. Roman roads were of several kinds, ranging from small local roads to broad, long-distance highways built to connect cities, major towns and military bases. These major roads were often stone-paved and metaled, cambered for drainage, and were flanked by footpaths, bridleways and drainage ditches. They were laid along accurately surveyed courses, and some were cut through hills, or conducted over rivers and ravines on bridgework. Sections could be supported over marshy ground on rafted or piled foundations.Corbishley, Mike: "The Roman World", page 50. Warwick Press, ...

Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy ( Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly 20% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beasts Of Burden
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or other products such as leather. The history of working animals may predate agriculture, with dogs used by our hunter-gatherer ancestors. Around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autobahn
The (; German plural ) is the federal controlled-access highway system in Germany. The official German term is (abbreviated ''BAB''), which translates as 'federal motorway'. The literal meaning of the word is 'Federal Auto(mobile) Track'. German are widely known for having no federally mandated general speed limit for some classes of vehicles. However, limits are posted and enforced in areas that are urbanised, substandard, accident-prone, or under construction. On speed-unrestricted stretches, an advisory speed limit () of applies. While driving faster is not illegal as such in the absence of a speed limit, it can cause an increased liability in the case of a collision (which mandatory auto insurance has to cover); courts have ruled that an "ideal driver" who is exempt from absolute liability for "inevitable" tort under the law would not exceed . A 2017 report by the Federal Road Research Institute reported that in 2015, 70.4% of the Autobahn network had only the advis ...

Freeways
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include '' throughway'' and ''parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arterials ...

Interstates
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, is a network of controlled-access highways that forms part of the National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico. The U.S. federal government first funded roadways through the Federal Aid Road Act of 1916, and began an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921. In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were still state-funded and maintained, however, and there was little in the way of national standards for road design. U.S. Highways could be anything from a two-lane country road to a major multi-lane freeway. After Dwight D. Eisenhower became president in 1953, his administration ...

Interrupted Time Series
Interrupted time series analysis (ITS), sometimes known as quasi-experimental time series analysis, is a method of statistical analysis involving tracking a long-term period before and after a point of intervention to assess the intervention's effects. The time series refers to the data over the period, while the interruption is the intervention, which is a controlled external influence or set of influences. Effects of the intervention are evaluated by changes in the level and slope of the time series and statistical significance of the intervention parameters. Interrupted time series design is the design of experiments based on the interrupted time series approach. The method is used in various areas of research, such as: *political science: impact of changes in laws on the behavior of people; (e.g., Effectiveness of sex offender registration policies in the United States) *economics: impact of changes in credit controls on borrowing behavior; *sociology: impact of experiments in ...
