The costs associated with crash injuries in Puerto Rico are based on the Highway Safety Manual 2010 version and the Federal Highway Administration data. They follow the crash-injury severity scale named KABCO. The model is based on a 2005 study of the Federal Highway Administration that used a 2001-dollar value that did not include Puerto Rico. However, Puerto Rico’s transportation and police agencies only use three types of crashes in their crash type distinction: fatal, injury, and property-damage-only. To adequately address road safety efforts in Puerto Rico, a crash-cost injured severity estimation was developed. This process was based on medical expenses and associated costs for each type of crash by revising the KABCO injury scale for injury-only motor vehicle crashes on Puerto Rico. A K-means cluster analysis was performed with the medical service data from traffic-related injuries to ascertain if the three-level KABCO categorization for traffic-related injuries fits the Puerto Rico data. As a result, the best cluster or group configuration that maximized the distance among groups and minimized the distance within groups was obtained.
