Quixote develops and manufactures highway safety products. As of February 4, 2010, Quixote Corp. was acquired by Trinity Industries Inc. Quixote Corporation, through its subsidiaries, develops, manufactures, and markets highway and transportation safety products to protect, direct, and inform motorists and highway workers in the United States and internationally. It operates through two segments, Protect and Direct, and Inform. The Protect and Direct segment offers energy-absorbing products, such as crash cushions, truck-mounted attenuators, sand-filled barrels, and water-filled barriers; and directing and guiding products, including flexible post delineators and glare screen systems. These products absorb and dissipate the force of impact in collisions between vehicles and fixed roadside objects, as well as prevent crashes and help control the flow of traffic by directing or guiding. The Inform segment provides advanced sensing products, which measure distance, count, and classify vehicles; weather sensing systems; computerized highway advisory radio transmitting systems; and other transportation equipment. These products offer information to prevent collisions from occurring and to ease traffic congestion. The company sells its products through its direct sales force and a distribution network to customers in the highway construction and safety business, local governments, airports, state and municipal departments of transportation, and other governmental transportation agencies. The company was formerly known as Energy Absorption Systems, Inc. and changed its name to Quixote Corporation in June 1980. Quixote Corporation was founded in 1969 and is based in Chicago, Illinois.
