Estimating the speed-crash relationship has long been a focus area of interest in roadway safety analysis. Because of many confounding factors that may influence both speeds and crashes, the relationship cannot be appropriately established without considering the corresponding roadway characteristics and accounting for their effects on speeds and crashes. Texas A&M Transportation Institute researchers Eun Sug Park, Kay Fitzpatrick, Subasish Das and Raul Avelar recently published a paper assessing the relationship among roadway characteristics, operating speed and crashes for city streets.
