... The 21 candidate case studies included incident management programs and policies, work zone management activities, ATM applications from international examples, and nonurban case studies that focused on weather and freight operations. Several criteria were established to guide the assessment and narrow the 21 candidate case studies down to 10 for further evaluation; however, a formal scoring process ultimately was not implemented.

... Once an effective modeling tool was identified, it was important to look at the key elements within the process and determine how these elements would be used to map business processes from transportation agencies. Process Model Approaches and Notations Considered A consistent approach to process diagram is needed to present the case studies and demonstrate that the actions or activities result in a specific or desired outcome.
