*- The generalized peak hour directional volumes for Florida's rural areas have a limit of 3-lane divided roadways, hence capacity of 1-lane is added to 3-lane divided roadways for the capacity analysis for 4-lane rural roadways.
Predictive Safety
The Crash Reduction Factors (CRF) developed by FDOT were applied to proposed improvements in the study area. FDOT Safety Office Crash Reduction Analysis Safety Hub (CRASH) program is a safety improvement tools used by FDOT to conduct benefit-cost analyses and calculate CRF (https://fdotwww.blob.core.windows.net/sitefinity/docs/default-source/roadway/qa/tools/crfguide.pdf?sfvrsn=2e360f88_2). The improvement in the Build Alternative decreases the total crashes by 13%. However, the improvement increases sideswipe, fixed-object, wrong-way and pedestrian crashes.
