But more than mechanical wizardry (魔法) , it was computers that transformed transportation in the late 20th century. In cars, they controlled the transmission, temperature and even helped drivers apply the brakes. Advanced computer systems in air traffic control tracked 32,000 flights per day. They helped control trains and urban mass transit systems. Radar and new navigational technologies made ship travel safer. Computers hooked into satellite systems kept track of every barge, every train, every truck – and even every package in the system. J) As for the future, who knows what it holds. What is clear is that technology will continue to change transportation and transportation will continue to change our lives.
