Studying WWD on Central Florida Expressways • Research study conducted by the
University of Central Florida (UCF) • Involved examination of: • Crash statistics • Citations • Reported WWD activity • Telephone survey of CFX customers
• Based on results of telephone survey: • Estimated that only 10% of drivers who see WWD activity call 911 • WWD driving activity may be under-reported • Data collection required to determine the full extent of the problem
Studying WWD on Central Florida Expressways • Study recommended a pilot deployment of WWD
countermeasures equipment • Pilot deployment will: • Test RRFB countermeasures • Collect data to help CFX determine the extent of WWD activity at
the pilot locations

Mainline Detection Equipment • Leveraging existing Wavetronix HD
sensors on mainline • 10 test locations to be equipped with Click 512! units to enable WWD detection • WWD detection data to be logged with vendor software, eventual goal is to use SunGuide

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
