Despite their wealth and modern road systems, traffic injury rates in Middle Eastern countries are generally higher than those in Western countries. The authors examined traffic injuries in Qatar during 2000-2010, a period of rapid population growth, focusing on the impact of speed control cameras installed in 2007 on overall injury rates and mortality. During the period 2000-2006, prior to camera installation, the mean (SD) vehicular injury death rate per 100,000 was 19.9±4.1. From 2007 to 2010, the mean (SD) vehicular death rates were significantly lower: 14.7±1.5 (p=0.028). Non-fatal severe injury rates also declined, but mild injury rates increased, perhaps because of increased traffic congestion and improved notification. It is possible that speed cameras decreased speeding enough to affect the death rate, without affecting overall injury rates. These data suggest that in a rapidly growing Middle Eastern country, photo enforcement (speed) cameras can be an important component of traffic control, but other measures will be required for maximum impact.
尽管中东国家拥有丰富的财富和现代化的道路系统，但交通伤害率通常高于西方国家。作者研究了 2000-2010 年期间卡塔尔的交通伤害情况，这一时期人口快速增长，重点关注 2007 年安装的速度控制摄像头对整体伤害率和死亡率的影响。在 2000-2006 年摄像头安装之前，每 10 万人的车辆伤害致死率平均（SD）为 19.9±4.1。从 2007 年到 2010 年，车辆死亡率明显下降：14.7±1.5（p=0.028）。非致命性重伤率也有所下降，但轻伤率有所上升，这可能是由于交通拥堵加剧和通知改善所致。速度摄像头可能降低了足够的速度，从而影响了死亡率，而不会影响整体伤害率。这些数据表明，在一个快速增长的中东国家，照片执法（速度）摄像头可以成为交通管制的重要组成部分，但还需要采取其他措施以达到最大效果。
