Collaboration between TRB, AASHTO, and FHWA Knowledge Transfer Workshop – June, 2013 Implementation Planning Workshop – October, 2013

Implementation plan targeted for FY2014 Deployment Strategy – parallel process: 1- Begin the development tasks that are identified through the IPW. 2- Identify potential agencies to implement the guide as a pilot and begin the implementation efforts.

Lessons learned from the pilot will be addressed through the development tasks.
