OBSERVATIONS
Agencies own and certify a large number of devices Many agencies use their own procedures & facilities Most agencies do not accept other agencies’ certification Some agencies apparently do not certify Perceived value of certification is credibility, technical
validity Perceived value for both network & project work Travel authorization, distance, & cost are potential barriers
to regional certification facilities Survey results may change post MAP-21

RECOMMENDATIONS
1. Update Survey Attempt equal or better response Refine and add small number of questions Author is willing to do Fall 2013
2. Supply results to stakeholders Respondents (states and provinces) RPUG Profile Quality Pooled Fund Study FHWA AASHTO
3. Explore interest of potential “centers”4. Identify “owner” for certification follow-up
