This article describes efforts by various state departments of transportation to make work zones safer for construction workers while preventing gridlock. More than 1,000 people were killed in work zone accidents in 2002, and more than 40,000 were injured. The Arkansas Department of Transportation (DOT) uses a virtual traffic operation center based in Connecticut to provide real-time traffic photos on line for motorists to learn road conditions. Michigan �s DOT is experimenting with a system of five trailers set up 1,500 feet apart to force drivers to merge in a systematic and safe way instead of rushing ahead to the merge point. The Illinois DOT is experimenting with automatic flagging equipment, which allows a flagger to turn the sign from stop to slow from a remote and safe location. The article also describes work zone intrusion devices such as alarms that transmit loud noises to warn drivers when two lanes are tapering to one.
