N2  - Speed is a key risk factor in road safety. The objective of this study is to investigate the relationship between speed characteristics and accident at urban signalized intersections. Accident prediction models are used for this purpose. Accident and speed data are collected at 65 urban signalized intersections. The speed-accident relationship is analyzed based on the developed models. It is found that both mean speed and speed standard deviation are positively correlated to accident frequency. Furthermore, the impact of mean speed and speed standard deviation on property damage only accidents is higher than on injury and fatal accidents. <br><br>KEYWORDS: Mean speed; Speed standard deviation; Accident frequency; Accident prediction model<p />
