As the commitment to improve highway safety emerged in the late 1960s and the philosophy of safer roadsides and clear zones took hold nationally there were maintenance issues that challenged the highway engineer to find a practical solution. Prominent among these issues were (a) tirepavement available friction, (b) influence of potholes and road surface roughness, (c) water accumulations, and (d) influence of pavement edge drop-offs. These issues were important because these conditions can never be completely eliminated in all roadways all the time. Thus it was important to be able to prioritize treatment of these conditions so that with limited funds the highest influence on safety could be achieved. This need was addressed by the Transportation Research Board (TRB) Surface PropertiesVehicle Interaction (AFD90) Committee. This committee set up a task group on Roadway Surface Discontinuities and Safety. That group was active from 1980 until the publication of TRBs first state of the art report in 1983. That report, The Influence of Roadway Surface Discontinuities on Safety, was the culmination of the task groups work.
