A traffic collision, also known as a motor vehicle collision (MVC), traffic accident, motor vehicle accident, car accident, automobile accident, road traffic collision, road traffic accident, wreck, car crash, or car smash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other stationary obstruction, such as a tree or utility pole. Traffic collisions may result in injury, death and property damage. A number of factors contribute to the risk of collision, including vehicle design, speed of operation, road design, road environment, and driver skill, impairment due to alcohol or drugs, and behavior, notably speeding and racing. Worldwide, motor vehicle collisions lead to death and disability as well as financial costs to both society and the individuals involved. Road injuries resulted in 1.4 million deaths in 2013, up from 1.1 million deaths in 1990. About 68,000 of these occurred in children less than five years old.〔 Almost all high-income countries have decreasing death rates, while the majority of low-income countries having increasing death rates due to traffic collisions. Middle-income countries have the highest rate with 20 deaths per 100,000 inhabitants, 80% of all road fatalities by only 52% of all vehicles. While the death rate in Africa is the highest (24.1 per 100,000 inhabitants), the lowest rate is to be found in Europe (10.3). ==Terminology== Traffic collisions can be classified by general type. Types of collision include head-on, road departure, rear-end, side collisions, and rollovers. Many different terms are commonly used to describe vehicle collisions. The World Health Organization use the term ''road traffic injury'',〔(【引用サイトリンク】title=WHO | World report on road traffic injury prevention )〕 while the U.S. Census Bureau uses the term ''motor vehicle accidents (MVA),''〔(【引用サイトリンク】title=The 2009 Statistical Abstract: Motor Vehicle Accidents and Fatalities )〕 and Transport Canada uses the term "motor vehicle traffic collision" (MVTC).〔(【引用サイトリンク】title=Statistics and Data - Road and Motor Vehicle Safety - Road Transportation - Transport Canada )〕 Other common terms include ''auto accident'', ''car accident'', ''car crash'', ''car smash'', ''car wreck'', ''motor vehicle collision'' (''MVC''), ''personal injury collision (''PIC''), ''road accident'', ''road traffic accident (''RTA''), ''road traffic collision (''RTC''), ''road traffic incident (''RTI''), ''road traffic accident'' and later ''road traffic collision'', as well as more unofficial terms including ''smash-up'', ''pile-up'', and ''fender bender''. Some organizations have begun to avoid the term "accident". Although auto collisions are rare in terms of the number of vehicles on the road and the distance they travel, addressing the contributing factors can reduce their likelihood. For example, proper signage can decrease driver error and thereby reduce crash frequency by a third or more. That is why these organizations prefer the term "collision" to "accident". In the UK the term "incident" is displacing "accident" in official and quasi-official use.〔https://trafficscotland.org/currentincidents/〕〔http://www.bbc.co.uk/travel/8714914/incidents/road〕 Historically in the United States, use of terms other than "accidents" had been criticized for holding back safety improvements, based on the idea that a culture of blame may discourage the involved parties from fully disclosing the facts, and thus frustrate attempts to address the real root causes. ==Signs and symptoms== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Traffic collision」の詳細全文を読む スポンサード リンク
