In Virginia…
a highway crash occurs every 4 minutes
a person is injured in a highway crash every 8 minutes
An average of 2 people dieevery day in highway crashes

VisionToward Zero Deaths
Mission• save lives and reduce crashes and injuries• data driven strategic approach• enforcement, education, engineering, and
emergency response strategies
Goalreduce deaths & severe injuries by half by 2030
Target –3 percent per year until 2016

Before-and-after Results

Where 113 highway safety-funded projectshave been deployed since 2004…
92%
Fatal Crashes
55%
Injury Crashes
Deploy Low-Cost/High-Benefit Solutions
What We Know:• Highway Safety Funding is very limited.• Severe crashes are spread out across our roadway network
As a result, we must:• Select projects based on data-driven approach• Take advantage of low cost solutions that can be deployed at
many locations (We call these SYSTEMIC projects)
For Example …
22
Example
Traditional IntersectionProject
• Rebuild IntersectionØ Move curbØ Add capacityØ Rebuild/replace signalØ Some R/W required
• Typical Cost: $2-4 Million• Typical Schedule: 2-4 years
• Typical crash reductionØ 10-15 crashes/year
23
Systemic IntersectionProject
• Deploy flashing yellowarrow at 25 intersections
• Approximate Cost: $500K• Approx. Schedule: 1 year
• Expected crash ReductionØ 36% of all left turn angle
collisionsØ Approximately 90
crashes/year
http://safety.fhwa.dot.gov/systemic/index.htm
FHWA Systemic Approach
Systemic Projects – Curve Delineation
25
Estimated Cost:à $5K/location
Estimated Crash Reduction:à 30-50% of all crashes
Estimated Schedule:à less than 1 year
Other Notes:FHWA proven safety countermeasure
Systemic Projects – Rumble Strips
26
Estimated Cost:à $7K/mile – center line RSà $12K/mile – shoulder RS
Estimated Crash Reduction:à 44-64% - center line RSà 36% - shoulder RS
Estimated Schedule:à less than 1 year
Other Notes:FHWA proven safety countermeasure
Systemic Projects – Flashing Yellow Arrow
27
Estimated Cost:à $20K/intersection
Estimated Crash Reduction:à 36 % of left turn angle crashes
Estimated Schedule:à about a year
Systemic Projects – Retroreflective TrafficSignal Backplates
28
Estimated Cost:à $5-7K/intersection
(much less if doing other work)
Estimated Crash Reduction:à 15 % of all intersection crashesà 28% of severe crashes
Estimated Schedule:à less than a year
Other Notes:FHWA’s proven safety countermeasure
Systemic Projects –Signal Timing
29
Elements:• Cycle length, split, Offset, Yellow
and Red Clearance intervals,pedestrian clearance interval,pedestrian phase selection.
Estimated Cost:à $5K/intersection
Estimated Crash Reduction:à 20-33 % of all crashes
Estimated Schedule:à less than a year
Systemic Projects – Road Diets
30
Estimated Cost:à $20-30K/mile for pavement
marking changes
Estimated Crash Reduction:à 20-47 % of all crashesà particularly rear end, angle, and
sideswipe crashesà risk reduction for peds and bikes
Estimated Schedule:à less than a year if coordinated
with resurfacing
Other Notes:FHWA proven safety countermeasure
Systemic Projects – Ped Refuge Islands
31
Estimated Cost:à $20-30K/location if no R/W needed
Estimated Crash Reduction:à 40-45 % of all crashes
Estimated Schedule:à 1-2 years
Other Notes:FHWA proven safety countermeasure
Systemic Projects – Other Ped/Bike Projects
32
Element w/ Estimated Cost:• Ped countdown SignalsØ $1200/Each
• Rectangular Rapid Flashing BeaconØ $30-40K per location
• HAWK SignalØ $90-120K per locationØ FHWA Proven Safety
Countermeasure• High-Visibility Crosswalk
Ø $5-10K/intersection
• Green Bike Lanes in conflict areasØ $20/square foot
Roadway Departure Plan
33
Roadway Departure Crash Definition
“A non-intersection crash which occurswhen a vehicle crosses an edge line or a
center line, or otherwise leaves thetraveled way.” (Source: FHWA)
34
Roadway Departure Plan
35
• Completed by FHWA
• Recommends low-cost,systemic countermeasures
• Focus on keeping vehicles onthe road
• Plan, spreadsheet and GISmaps available onOutsideVDOT Page. Accessby clicking HERE.
