In recent years, there has been an increased focus on Traffic Incident Management (TIM) and incorporation of the Incident Command System (ICS) to reduce traffic congestion on the nation's Interstates. In fact, studies show that for every minute a freeway lane is blocked due to an incident, there is a corresponding time of four minutes of travel delay, and the likelihood of a secondary crash increases by 2.8% for every minute that the primary incident remains a hazard. Efficiencies resulting from adoption of coordinated multi-agency response through ICS can reduce the impact of nonrecurrent traffic congestion caused by traffic incidents on major roadways. This project investigated the effectiveness of multi-stakeholder agency coordinated ICS strategies for managing traffic incidents by considering their potential impacts in reducing incident duration. Between 2012 and 2013, there were 129 fatal incidents recorded on SC Interstates. Roughly half of the fatal incident recovery times (dispatch of response to incident cleared) were in excess of six hours, with maximum recovery times well over 12 hours. These clearance and recovery times are significantly higher than those in other states. States which have implemented enhanced ICS and TIM procedures are consistently achieving major incident clearance times of one and a half hours or less. After analyzing the current state-of-practice in South Carolina, and national best practices, the potential areas for improvement in incident response were identified. The TIM areas most in need of improvement were response and clearance strategies, with major gaps noted in towing, coroner, HAZMAT, and crash investigation procedures. |
