Guardrail Need paper by Wolford and Sicking

State KS
Description Text

I have been reading Transportation Research Record 1599, Guardrail Need, Embankments and Culverts which was written by Dan Wolford and Dean Sicking and have found it extremely useful.  I am interested in running a similar analysis using updated accident costs and RSAP to put together similar charts for use by our local County and City partners.  Would it be possible to get the matrix of site situations used for this report?  We would like to use it as starting point for our analysis and add to it.


Please do not hesitate to call if you have any questions.


Thank you in advance for any assistance you can provide.

I have dug into the materials associated with that paper. The original research report has more detail and is attached. Let me know if that helps any.


I have not been able to locate the actual matrix of sites used in the modeling yet. I will have a student do some digging and let you know if we find anything.
