Book excerpt: This evaluation of the second Strategic Highway Research Program (SHRP2) Traffic Incident Management (TIM) Responder Training Program focuses on three areas: the dissemination of TIM trainings and concepts across the country, responder and agency adoption of SHRP2 TIM concepts, and improvements in key TIM performance metrics. From 2012 to 2015, SHRP2 TIM trainings reached over 150,000 emergency responders—representing a variety of responder disciplines—across the country. Responders and agency supervisors reported that SHRP2 TIM concepts improved on-scene safety and that these concepts were straightforward to apply. To identify improvements in TIM metrics that resulted from the trainings, the evaluation team focused on Metropolitan Phoenix and Eastern Tennessee as case studies. In Metropolitan Phoenix, the evaluators found that SHRP2 TIM trainings contributed to decreases in secondary crashes that involved emergency responders. In both Metropolitan Phoenix and Eastern Tennessee, TIM trainings contributed to reductions in roadway- and incident-clearance times.
