SOME NOTES ON: "WHAT TASKS IS A TRAFFIC CONFLICTS TECHNIQUE INTENDED FOR?"

Road safety can be measured by means of accident analysis. Another measuring method is the conflicts technique. In this article the validity of the conflicts technique is related to the reliability of the two measuring methods. A decision procedure is given for deciding between the two methods when the accident history is incomplete. The alternative of combining both methods is described. An example is given of a decision procedure between the criterion variables traffic volume and accident counts. /TRRL/
