The Crash Costs for Highway Safety Analysis Tool assist engineers, planners, designers, analysts, researchers, and managers involved with highway safety analysis and highway safety management with performing crash cost calculations. Crash cost calculations include translating, converting, weighting, adjusting, or updating existing crash costs. The costs rare based on two injury scales: Maximim Appreviated Injury Scale (MAIS) and the KABCO scale, in which K = fatal injury, A = suspected serious injury, B = suspected minor injury, C = possible injury, and O = property damage only.
