102 Chapter 5 Conclusions and Future Research 5.1 Conclusions Throughout the research period, compatibility between vehicles and roadside hardware systems was investigated. Findings of the project indicated that the performance of roadside systems during typical crash configurations varied greatly according to the overall characteristics of the impacting vehicle class.

103 effect of these improvements would lead to reduced fatality counts for a given impact condition when compared with crash outcomes for impacts involving earlier model vehicles. Based on the analysis of guardrail, concrete median barrier and small to medium pole impacts involving each of the investigated vehicle classes (i.e.
