11 FHWA Nine Proven Safety Countermeasures You are encouraged to use FHWA resources as you develop your projects. * * * * 11

12 Lane Departure Countermeasures Curve safety, rural two-lane roadways, run-off-road crashes 12

13 Where are roundabouts appropriate? Roundabouts are not an appropriate treatment for all intersections, but may be particularly advantageous at intersections with/near: High-crash rate or a higher severity of crashes intersection/bike/ped Complex geometry (skew, 4+ legs, driveways) Freeway interchanges Closely spaced intersections Three-legs with high left turning volumes Transit corridors Bike/Pedestrian Volumes Transition to a lower speed zone Up to 65% crash reduction compared to conventional signalized* New statewide requirement: 2 roundabouts per district in FDOT 5 Year Work Program 13

14 Where are road diets appropriate? On most corridors, eliminating travel lanes is not recommended. Road diets should only be considered on corridors with a combination of the following characteristics: High-crash rate or a high severity of crashes Mode split imbalance: High volumes of bikes/peds Excess capacity Surrounding land use and roadway design do not match Right-of-way is constrained Excessive speeding Close proximity to schools Pedestrian generators Transit emphasis corridors 30-50% crash reduction depending on configuration 14

15 Where are road diets appropriate? On most corridors, eliminating travel lanes is not recommended. When considering a road diet to improve safety, you should take note of impacts to surrounding area & adjacent facilities: Things to look for! Long-term traffic generators Will the nature of planned/new development generate new demand for motor vehicle capacity? Long-term land use vision Will the nature of planned/new development generate new bicycle/ pedestrian activity? Network connectivity Can displaced traffic be accommodated on alternate routes? How will this impact regional connectivity? Is there community support? 15

16 Where are road diets appropriate? Nebraska Avenue Road Diet Project SR 45 (state highway system) Before: 4 lane undivided After: 2 lane with Two-way left-turn lane & bike lanes 16

17 Where are road diets appropriate? Nebraska Avenue Road Diet Project SR 45 (state highway system) Post-evaluation Overall reduction in Crash frequency (-68%) Crash rates (-61%) Crash severity (-45%) Traffic dispersion no significant trend Reduction or steady volumes on all parallel adjacent routes (US 41/Florida Ave, I-275, 15 th Street, 22 nd Street) Other concurrent factors influencing route choice & historical volumes: i.e. interstate construction, regional economic trends 17

18 Mid-block crossings Volume: A 3-day pedestrian count must be submitted with every new mid-block crossing proposal. All new marked crosswalks shall comply with the minimum requirements in FDOT Traffic Engineering Manual Section 3.8*. This should be the first step in any study. Placement: Is there an adjacent intersection with marked crosswalks? All intersections are legal crosswalks, whether marked on unmarked. Florida Statutes Always consider marking an adjacent unmarked crosswalk before you introduce a new mid-block crosswalk on a corridor. Configuration: 4 lanes or greater? Consider a raised median and a full pedestrian signal*. Rectangular Rapid Flashing Beacon (RRFB) 18

19 Traffic Control at pedestrian crosswalks Pedestrian Hybrid Beacon/ HAWK The HAWK is currently being evaluated in Tallahassee to determine effectiveness over a traditional traffic signal. We currently do not have a standard for HAWK signals in Florida. When proposing a new crosswalk, consider an RRFB or a full traffic signal. All traffic control devices shall comply with the minimum requirements in FDOT Traffic Engineering Manual Section 3.8*. 19
