This report documents the process used to test and refine the National Traffic Incident Management (TIM) Responder Training curriculum originally developed through SHRP 2 Project L12 so that it could be implemented. The improvement process involved hundreds of responders in four states: Florida, Montana, Tennessee, and Virginia. Over the life of the project, the train-the-trainer course was delivered to a multidisciplinary group of TIM trainers with the results observed by a panel of experts. Between deliveries, hundreds of improvements were made to the course materials. Once the project was completed, the revised curriculum was delivered to the Federal Highway Administration, U.S. Department of Transportation. The course is now being rolled out on a nationwide basis, making this one of the first products of the SHRP 2 program to be implemented.
