Round robin exercise on road transportation data

This paper presents a round robin exercise recently undertaken under the auspices of the Transportation Stresses working group of the Committee of European Environmental Engineering Societies (CEEES). The concept of the CEEES road transportation round robin exercise arose from a survey initiated in 1989. That survey polled some 33 European agencies and found that no general consensus existed as to how improved road transportation test severities could be derived. A round robin exercise was suggested as one method by which the range of methodologies in use could be determined. As well as identifying the range of methods in use for the assessment of road transportation dynamic data, the round robin exercise was also intended to quantify any variations arising from the use of different methodologies. The intent was that each participant should utilize what ever method they considered appropriate. To this end the requirements for active participation were set so as not to influence the participant's choice of approach. In practice this meant imposing relatively few constraints. As a consequence some limitations arose in the quantitative comparisons. Reprinted with permission from the Journal of the IES, July/August 1993, Institute of Environmental Sciences.
