N2  - This study evaluated the effectiveness of speed cameras in reducing the number of road crashes on a freeway from Abu Dhabi to Al Ain in the Emirate of Abu Dhabi. Crash data was collected for three years before the introduction of speed cameras and three years subsequently. The data was analyzed  using "Before and After with Comparison Group" method. The common problems in 'before and after' studies such as regression to mean, maturation, and migration, were minimized through dividing the road into several sections. The road sections of approximately similar lengths and in close proximity to one another were compared.     This study has found that speed cameras were effective in reducing the number of crashes on the Abu Dhabi to Al Ain road. Furthermore, it  was found that the effectiveness of speed cameras was more on sections where the intensity of cameras was high. The study recommends that the deployment of more speed cameras in the Emirate of Abu Dhabi would help in improving the road safety.<p />
