45 chapter four Injury Data analysIs IntroDuctIon This chapter provides detailed findings from the analysis of injuries and fatalities that occur at highway work sites. Specifically, the data analysis aimed to quantify and compare injury and fatality incidence rates according to injury type, severity, project type, and other related characteristics.

46 Owing to the methodology used to obtain data by the IIF program, the data are separated into two primary categories: fatal occupational injuries and nonfatal occupational injuries and illnesses. The injury and fatality records in each of these two categories contain the same general information except that the fatality records are coded more specifically in terms of the type of industry.

From page 46... ...
47 When these values are explored on a state-by-state level, individual state DOTs can determine how the fatality rates for these specific demographics align with available employment demographics in the highway, street, and bridge construction industry in that state. Discrepancies between the two, particularly in demographic divisions for which the fatality rate is higher, can indicate areas where state safety efforts might be focused.

54 All of these figures show the limitations of these data in terms of nationwide investigation of worker fatalities in highway work sites. States that have their own FACE program do not necessarily conduct reports relating to highway work zones at the same frequency.

59 the website can cross tabulate these 1,400 incidents with any of the recorded metrics about the incidents. This analysis can include such information as crash severity, incident type, or information about the environment in which the incident occurred, such as location, weather, or time of day (VTTI 2016)
