79 3.3.1. Webinar Objectives The objectives of the webinar were to: • Describe current methods used to quantify and monetize TIM outcomes along with their levels of effort, complexity, and data needs as uncovered through Task 2a/b document, "Review of Traffic Incident Management Evaluation Methods." • Explain the basis behind some commonly used assumptions to estimate TIM outcomes as identified within the Task 2a/b document, "Review of Traffic Incident Management Evaluation Methods." • Share first perspective accounts of rationale behind why and with what frequency states calculate TIM outcomes, and how they use findings for internal and external communications of program value from the State Stakeholders participating in this project.
