proposed safety improvements rather than projects that would increase capacity. To determine specific problem locations, the study team evaluated CDMS crash data collected from 2014 to 2018 (see Figures 11 and 12). Key observations: Within the study area, Gibsonton Drive/Boyette Road between I-75 and Balm Riverview Road, is identified as one of the County’s top high crash corridors. Gibsonton Drive/Boyette Road, between I-75 and Balm Riverview Road, is a high crash area during both AM and PM peak period. The US 301 and I-75 intersections with Gibsonton Drive have high crash occurrences in both the AM and PM periods. Several intersections along Gibsonton Drive and US 301 have high crash occurrences in the PM period. US 41, I-75 and US 301 have higher rates of crashes in the PM period compared to the AM period. US 41 intersections with Riverview Drive, Gibsonton Drive and Symmes Road have high crash occurrences during the PM period. CRASH LOCATION BY TYPE The study team also used the CDMS crash data from 2014 to 2018 to evaluate the types of crashes and where they occurred within the study area. Figures 13 and 14 show crash locations by type for AM and PM peak periods. Key observations in the AM peak period: A high frequency of rear end crashes occurred along Gibsonton Drive between Prevatt Street and US 301, and along US 301, I-75 and US 41.
The majority of crashes within the Gibsonton area are rear-end crashes. They are concentrated along Gibsonton Drive/Boyette Road, I-75, US 41 and US 301. This is not surprising given the area has a limited secondary roadway network forcing motorists to travel on these major arterials that carry the bulk of the volume. In addition, portions of these roadways allow for higher speeds followed by sudden and abrupt stops due to long queuing at intersections, contributing to high frequencies of rear-end crashes. CRASH HOT SPOTS Plan Hillsborough’s Vision Zero Plan was prepared in 2017 by the Hillsborough MPO, in partnership with Hillsborough County; the Cities of Tampa, Temple Terrace, and Plant City; and the Florida Department of Transportation (FDOT) in support of reduced fatalities and serious injuries on roadways. Figure 10 shows Hillsborough County’s top 20 corridors and crash spots with the highest number of severe injury crashes per mile between 2014 and 2018. The top 20 corridors with severe injury crashes are represented by black lines along the roads. The Gibsonton Drive/Boyette Road from I-75 to Balm Riverview Road segment ranks 2nd on the Top 20 Severe Crash Corridors identified in the Safe Streets Now, Vision Zero, Action Plan. There’s an ongoing effort by the Hillsborough MPO, conducting a Speed Management Study. Based on the Managing Speed on Hillsborough’s High Injury Network study draft the top 20 High Injury Network (HIN) corridors were assessed with regards to posted speed and context class and found that the posted speed on the Gibsonton Drive/Boyette Road from I-75 to Balm Riverview Road segment was 10 MPH over national practice. The study also developed a top 20 priority matrix, where the Gibsonton Drive/Boyette Road segment scored medium priority. In addition to the speed management study, a Vision Zero Corridor study on Gibsonton Drive was recently completed that
