TraffiCalm’s Sequential Chevrons have become an ideal MUTCD Compliant solution being deployed on roads and highways that have the potential for accidental and / or catastrophic vehicle lane departures.

Most curve-related accidents and fatal crashes involve single vehicles leaving the roadway and striking fixed obstacles.  The greatest number of fatalities don’t necessarily occur on highways but rather occur on rural county or urban conventional roads.

Our Sequential Chevron System is engineered to give drivers a higher level of visual guidance when approaching these curves.  This is being successfully accomplished through an Effective 30° Angularity.

Multiple Chevrons signs in a single location are configured in a single wireless network and flash sequentially in the direction of traffic.
