Wrong Way Driving Statistics
• Wrong way collisions
• 3% of crashes on high-speed divided
highways
• Fatality rate: 12-27 times higher than other
types of accidents
• Nationally between 2004 and 2009:
• 1,566 fatal wrong way crashes on limited
access highways
• 2,139 fatalities
• Averages 260 fatal collisions nationally
• Averages 360 fatalities per year

Studying WWD on
Central Florida Expressways• Research study conducted by the
University of Central Florida (UCF)
• Phase I Study (2012 – 2013)
• Examined crash reports, citations, conducted phone survey
• Determined WWD driving activity may be under-reported
• Data collection required to determine the full extent of the problem
• Phase II Study (2014 – 2015)
• Provided research support during deployment of first pilot ramp
• Phase III Study (Under negotiation)
• Would investigate additional deployment scenarios

Parking Lot Testing
• Temporary parking lot test
conducted to verify
technology
• Tested visibility of
beacons during day and
night conditions
• Experimented with radar
detection zones in a
controlled environment

Preliminary Lessons-Learned
• Two light bars per sign (top and bottom) will be used to
improve visibility of beacons.
• Initial test only had one light bar.
• Two pair of signs will be deployed at each ramp (beacons
at the remote pair slaved to the first pair).
• Provides enhanced visibility of warning in the event the driver
passes the first sign before beacon activation

Future Considerations
• Phase III Research Study:
• Document performance of pilot system over the next year
• Explore emerging technologies for future consideration
• Deployment of sensors at additional ramps
• Incorporate lessons-learned from pilot deployment
