FEASIBILITY OF DETERMINING THE INCREMENTAL EFFECTIVENESS OF ACCIDENT COUNTERMEASURES. FINAL REPORT

This report documents the development of a generalized methodology for determining the incremental effects of accident countermeasures employed individually and in groups. Two basic experimental designs are presented, and each is illustrated in an experimental plan for two groupings of countermeasures in two common highway situations. An assessment is made of the feasibility of implementing the methodology with respect to practicality, reliability, validity, time, cost, and expected benefit. The study concludes that while the methodology can produce incremental effects for many countermeasure groups in the more common highway situations, there are some serious disadvantages in terms of practicality, time, and cost.
