In Georgia, the HERO motorist assistance patrol program and NaviGAtor incident management activities saved more than 187 million dollars yielding a benefit-to-cost ratio of 4.4:1.
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 benefits above and the value of HERO motorist assistance resulted in a cost savings of more than 187 million dollars, which was used to calculate a benefit-to-cost ratio of 4.4:1. These productivity benefits are summarized in the table below.
