Curve Warning & Guidance Solutions

Across the world, traffic accidents, injuries and deaths on curves are disproportionately higher than on other road types. The average accident rate for horizontal curves is about three times the average accident rate for straight segments. Poor visibility, excessive speed and lane deviations are just a few contributing factors to head-on crashes, roadway departure and roll-overs.

SEL Road SignThe day and night curve warning & guidance solution

Wireless communication, SELSync™ synchronization & 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.
