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.
