Equipment Crossing

TTC Word Message Sign, EQUIPMENT CROSSING

When the normal function of the roadway is suspended, Temporary Traffic Control (TTC) planning provides for continuity of the movement of motor vehicle, bicycle, and pedestrian traffic. The primary function of TTC is to provide for the reasonably safe and efficient movement of road users through or around TTC zones while reasonably protecting workers, responders to traffic accidents and equipment.

MUTCD -Section 2C.01 Function of Warning Signs

Standard: The use of warning signs shall be based on an engineering study or on engineering judgment.

Guidance: The use of warning signs should be kept to a minimum as the unnecessary use of warning signs tends to breed disrespect for all signs. In situations where the condition or activity is seasonal or temporary, the warning sign should be removed or covered when the condition or activity does not exist.

Support: Warning signs call attention to unexpected conditions on or adjacent to a highway or street and to situations that might not be readily apparent to road users. Warning signs alert road users to conditions that might call for a reduction of speed or an action in the interest of safety and efficient traffic operations.
