In Georgia, the Navigator incident management program reduced secondary crashes from an expected 676 to 210 in the twelve months ending April 2004.
The benefits of the NaviGAtor incident management program were determined during a before-and-after study that analyzed twelve months of data (i.e., May 2003 to April 2004) from incident logs. The "before" conditions were estimated by analyzing incident information when a HERO could not respond, analyzing incidents that occurred outside of the NaviGAtor coverage area, and using public safety dispatch logs and personnel surveys to predict incident timelines when no NaviGAtor resources were employed. By comparing "before" conditions with "after" conditions when NaviGAtor incident management strategies were utilized, the benefits were determined in four areas: safety, mobility, energy and environment, and productivity.
The incident management program reduced secondary crashes in the NaviGAtor coverage area by 69 percent. It was estimated that the secondary crash rate was reduced from 676 to 210 crashes annually.
This study determined the benefits of the incident management program only. It did not quantify all of the benefits of the NaviGAtor system.
