Improving highway safety through speed management

根据世界卫生组织(WHO)的数据，每年全球范围内的交通碰撞导致120万人死亡。到2020年，道路交通伤害预计将成为全球疾病负担的第三大贡献者。除了造成社会痛苦和痛苦外，交通碰撞还会造成巨大的经济成本。2004年加拿大交通事故造成的社会损失估计为627亿美元。虽然自1970年S以来，发达国家的交通安全状况不断改善，但数据显示，在过去的十年里，死亡人数相对持平。加拿大也不例外，在2000年以前，死亡人数一直在稳步下降。另一方面，自2000年以来，与交通有关的死亡人数一直在2004年的最低2 430人和2006年的最高2 610人之间波动。

According to the World Health Organization (WHO), worldwide traffic collisions cause the death of 1.2 million people every year. By 2020, road traffic injuries are predicted to become the third largest contributor to the global burden of disease. In addition to the social pain and suffering they produce, traffic collisions cause significant economic costs. Social costs resulting from traffic collisions in Canada in 2004 were estimated at $62.7 billion. While continuous improvements in traffic safety have been recorded in the developed countries since 1970's, data show that the numbers of fatalities have relatively flattened over the past decade. Canada is no exception, where the number of fatalities had steadily decreased over time until the year 2000. On the other hand, the number of traffic related fatalities since 2000 has been fluctuating between a minimum of 2,430 in 2004 and a maximum of 2,610 in 2006.
