FATAL TRAFFIC CRASH FACTOR: MOTOR VEHICLE SPEED Traffic crashes where speed was considered a factor for Hawaii County is in line with the State of Hawaii, however both are significantly higher than the national average, as 41% of Hawaii Island's fatal traffic crashes involved excessive vehicle speed (see Figure 9). The majority of these speed-related traffic crashes occurred on roads with a posted speed limit of 35 mph or less which is lower than the national average (see Figure 10). This data is misleading as faster motor vehicle speeds can be correlated with a higher likelihood of a pedestrian dying if hit. Map 4 identifies the location of speed-related fatal traffic crashes. Communities of concern, roadway ownership, and the location of available police stations and hospitals have been delineated as well ` ISLAND FATAL TRAFFIC CRASHES Speed-Related Non-Speed-Related YEAR Traffic Collisions Traffic Collisions Speed-Related Traffic Collisions 2013 Hawaii Island 2014 2015 State of Hawaii 2016 42% 2017 Nationwide 2018 27% 0 5 10 15 20 25 30 35 Number of All Fatal Traffic Collisions OF . . .
