Maintenance Work Zone Safety Devices Development and EvaluationAuthor/Presenter: Stout, Dale; Graham, Jerry; Fish, Joe; Hanscom, Fred
This report presents the findings of tests and evaluations of several new work zone safety devices. The prototypes of the 25 devices were designed, developed, fabricated, tested, evaluated, and refined. The devices were organized into 7 groups: barriers; warning devices; rumble strips; delineation devices; lighting devices; signs; and promising concepts. Twelve devices successfully passed the evaluation stage: salt spreader/truck mounted attenuator interface; the portable crash cushion; the ultrasonic detection alarm; the infrared intrusion alarm; the queue length detector; the portable rumble strip; the direction indicator barricade; the opposing traffic lane dividers; the snowplow blade markers; the flashing stop/slow paddle; the portable sign and stand; and the remotely driven vehicle.
