BlinkerChevron Curve Warning System

Intelligent Warning Systems

Applications: Two-lane, 55 mph Curves • High  -speed, Multi-lane Expressway Curves • Dangerous Horizontal Highway Curves

BlinkerChevron Curve Warning System and the BlinkerBeam® wireless communication, BlinkSync™ synchro-nization and chevrons function dynamically to warn and guide motorists through a dangerous curve once activated; by directing the chevrons to flash sequentially – delivering the “pull-through” effect. The system flash pattern and timing are easily programmed wirelessly from the Windows-based software using a PC or laptop, enabling the user to tailor the flash sequence to match the speed of traffic and the size of the curve.

Features

  • Reduce Speed-Related Crashes
  • Reduce Head-On and Cross-Median Crashes
  • Prevent/Mitigate Roadway Departure Crashes
  • Green, Solar Power – Zero Electrical Costs
  • Delineates Curve
  • Install Anywhere

Federal Highway Administration Evaluation

A Federal Highway Administration evaluation project found that a solar-powered traffic signage system reduces vehicle speed and crashes on horizontal curves, where the crash rate is triple that of other highway segments.

More than a quarter of fatal crashes occur at horizontal curves, and the majority of curve-related crashes involve roadway departure because of speeding or driver error.

The team conducted a speed analysis to determine the safety benefits of the system:

Intelligent Warning Systems

The system was effective at reducing vehicle speeds during all data collection periods from one to 24 months after installation, which suggests that drivers don’t get used to the system and begin to ignore it over time.

More drivers traveled at or slightly below the speed limit after the system was installed, but the largest reduction was in drivers exceeding the speed limit by 20 or more miles per hour.

Higher decreases were found at the point of curvature, which suggests that drivers respond to the system and reduce their speed before entering the curve.
