Abstract
Secondary crashes resulting from traffic queues are a significant national safety concern. Traffic Incident Management (TIM), which involves coordinated multi-agency response to roadway incidents, is widely recognized as an effective approach to mitigating these crashes. This study aimed to develop a library of after-action case studies to support TIM training and evaluate current practices. Leveraging connected vehicle data alongside crash reports, camera footage, and dispatch audio, the research compiled 267 comprehensive after-action review reports for incidents across Indiana from June 2020 to March 2025. These reports, indexed by key attributes such as date, location, and incident type, form what is believed to be the most extensive archive of TIM case studies in the U.S. Key recommendations emphasize the value of integrating camera imagery, connected vehicle data, and dispatch audio to enhance responder training, promote peer learning, and improve situational awareness. This resource serves as both a training tool and a model for developing future TIM documentation nationwide.
