EVALUATION OF SEVERITY OF COLLISIONS WITH ROADSIDE FEATURES: DATA NEEDS. SUMMARY OF PART 2

In support of benefit/cost analysis procedures of roadside safety programs, the seven presenters in this session outlined data needs and limitations associated with current data acquisition methods using computer simulation and physical testing. From the standpoint of physical testing and analysis, data needs for cost-benefit analysis procedures have been assessed. Whereas considerable information pertaining to a specific appurtenance hardware items can be acquired before the item is introduced into actual service, it is recognized that extensive in-service evaluation including numerous collision cases is necessary to develop sufficient input to the cost-benefit equation.
