EVALUATION OF SEVERITY OF COLLISIONS WITH ROADSIDE FEATURES: DATA NEEDS, SUMMARY OF PART 3

Two issues of interest arose in these discussions. One was the need to distinguish between two types of in-the-field accident research, statistical research evoluting how well a given piece of hardware reduced injuries to occupants of a striking vehicle and clinical studies determining the failure modes of a given piece of harware once it is put in the real world. The concensus was that the former is the most important in that it alone can provide severity reduction factors to the cost/benefit analyses so desparately needed. This lack of good statistical studies generate the second major point of the discussions. The current requirements for "evaluation" of all improvements by every state in every project result in inadequate funding for a given evaluation, pitifully poor research designs and thus results of little or no value. A possible alternative approach would be to require instead are well-designed evaluation with control on comparison groups, so that each state would produce one new piece of information a year.
