Based on a review of State SHSPs, FHWA identified the eight SHSP emphasis areas common across most States. These emphasis areas are used in the HSIP online reporting tool for categorizing HSIP projects. Figure 20 presents the number of HSIP projects categorized by SHSP emphasis area. For consistency and national reporting purposes, state-defined SHSP emphasis areas were assigned to these emphasis areas, where possible.
About 40 percent of the projects were categorized as "Roadway Departure" (33 percent in 2014 and 42 percent in 2015), 29 percent were categorized as "Intersections" (27 percent in 2014 and 31 percent in 2015), 13 percent categorized as "Unknown/Other" (26 percent in 2014 and 14 percent in 2015). Examples of other categories used by the States include: "Highway infrastructure", "Railroad", and "Lighting".
