V. Crash Data and Analysis Crash data for E. 131 st Avenue within the project limits was processed using the most recent three-year data from the Hillsborough County Crash Data Management System (CDMS). A total of 246 crashes were reported along E. 131 st Avenue from N. Nebraska Avenue to Bruce B Downs Boulevard during the three-year analysis period from 2015 to 2017. Most of these crashes occurred at the Bruce B Downs Boulevard intersection, and no fatalities were reported for the three-year analysis period. Crash locations are depicted by severity in Figure 2-7 . Appendix VI provides a summary of the crashes per year and summarizes crashes by type. The analysis indicated that 76.8 percent of the crashes occurred at intersections, whereas 23.2 percent occurred at mid-block locations. The crash analysis at the intersections included a 250-foot influence area. Crash data summaries for the intersections and a detailed crash data table are provided in A ppendix VI . Taking the 250-foot influence area at the intersections into consideration, the crash analysis segment of E. 131 st Avenue from N. Nebraska Avenue to Bruce B Downs Boulevard is 1.65 miles in length. The
actual crash rate computed is 11.701 crashes per million vehicle miles traveled (VMT). Table 2-4 summarizes the segment actual crash rates as compared to the Hillsborough County-wide average crash rate of 2.226 for similar facilities. The analysis shows the corridor segment had an actual crash rate higher than the critical crash rate, as well as the county-wide average crash rate. If a segment has an actual crash rate that is higher than the critical crash rate (i.e., safety ratio >1.0), it may indicate a safety deficiency along the corridor. Methodology for determining different crash metrics and crash rates are presented in Appendix VI . The analysis results indicate Bruce B Downs Boulevard intersection as a high crash location with an actual crash rate greater than the critical crash rate and a safety ratio greater than 1.0 as compared to similar county-wide facilities. At the study intersections, the highest crash type reported was rear-end type crashes resulting in property damage only and most occurred during daylight hours.
