This target is based on Georgia's roadway types as wel as the number of cars and trucks using the roadway system. This measure evaluates GDOTs efforts to reduce fatalities on Georgia's roads. 1000 1550 year 217) Strategic Objective Reduce the number of fatalidies by 41 each year. Road to Improvement The State did not meet the reduction target of 41, As of early March 2018, there were 1550 Fatalities in CY 2017. However, the final numbers are subject to change due to fatalites' numbers still being reported and verif ed. Unfortunately, this number remains well above the low of CY 2014. GDOT is continuing its "Drive Alert Arrive Alive' campaign into CY 2018 and has expanded the program with strategic partnerships with local media In addition, continued investment through the Highway Safety Improvement Program in both systemic and data driven projects continuing to help drive this number down Annual-Fatality Trend on Georgia's Roadways 2500 2000 1500 2013 2008 2010 2011 2012 2009 2015 2016 2018 Disclaimer: This e age 5 op bed 30 be le ea m nter et pare ae 10 a aco e own 80 E bo sen accuracy, compeeness.eaoy' or suitaany tr any parocuar alpose orns mom ason and data contared on e c art above may not as a pro er if le ea er browsers The eor a De a mere o Tens onat on me es no e resenta on o wa anties. m iec or e essea concen g me wenste.
