operating speed, and traffic conflicts were the two surrogates that have definitive links to
MVC occurrence or severity, and are included in the Synthesis.
As the road safety knowledge-base is continually growing, it is important that the
practitioner have an understanding of how to appraise new evidence and integrate the
findings with those contained herein. To this end, appendices have been provided on
evidence-based road safety, critically reviewing literature, and the proper use of safety
performance functions. In hopes that practitioners will be encouraged to conduct and
document their own research, a further appendix is provided on conducting and authoring
research.
Finally, readers should exercise caution in applying the results contained in this Synthesis
to situations under examination. Apart from the critical review for methodological flaws
in the research, readers must also consider the limitations of transferring research
conducted in one jurisdiction to another jurisdiction. Specially, differences in crash
reporting, crash severity classifications, driver populations, the vehicle fleet, road system
legislation, and design standards may limit the applicability of the reported results to the
jurisdiction in which the research was performed.
