The Day and Night Curve Warning and Guidance Solution
Applications: Two-lane, 55 mph Curves • High-speed, Multi-lane Expressway
Curves • Dangerous Horizontal Highway Curves
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.

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:
