Texas Department of Transportation Purchases USA Signal Technology's Energy-Saving, Wireless Controlled, LED Powered "Intelligent" Lane Control Signals

DALLAS, TX -- (MARKET WIRE) -- April 23, 2007 -- USA Signal Technology, Inc. (PINKSHEETS: USST) (www.usasignal.com) has received its first purchase orders from the Texas Department of Transportation for production evaluation units for field testing of its proprietary LED (Light Emitting Diode) "Intelligent/Wireless" Lane Control Signals (LCS) that utilizes the latest National Transportation Communications for Intelligent Transportation Signals (NTCIP Protocol).

Lane Control Signals are those ever-present traffic signs with illuminated colored symbols on highway bridges and overpasses. The symbols show a specific lane's traffic condition: a green arrow for a lane flowing freely, a yellow arrow or yellow "X" for a slow lane, and a Red "X" for a lane that is shut down.

USA Signal Technology developed the wireless controlled, LED-LCS system at the request of the Texas DOT to replace about 2,200 existing lane control halogen/fiber-based signals that are prone to failure and consume over 10 times the energy. The first LED-LCS signals purchased will be used for field testing.

In addition to replacing the present halogen/fiber-based signals, Texas DOT has suggested that it may install a comparable number of LED-LCS systems in cities, such as Houston, that have not yet installed halogen/fiber units due to their failure rate and high operational costs.

USA Signal Technology LED Intelligent Lane Control Signals that cost between $5,000 and $7,000 each are extremely energy efficient since they powered with only 10 watts of electricity, require almost no maintenance and offer continuous intelligent feedback to a centralized control location. In comparison, the tens of thousands of conventional Lane Control Signals now deployed across the nation are powered by an array of halogen lights through fiber optic harnesses that require 150 watts of power, are high maintenance, often unreliable and require local controllers within the unit.

What makes USA Signal Technology's LCS "intelligent," is that unlike present Signals, it is equipped with a microcontroller that provides wireless communication with a central location, redundant power supplies to function during blackouts and brown-outs, and several other advanced features highly sought by DOTs. This allows for lower installation costs and extremely less on-going maintenance expenses compared to current fiber optic-halogen Signals. Most important, because of increased reliability and the ability to alert a central controller if a particular LCS will be in need of repair, or has actually stopped functioning, highway safety is greatly enhanced.

With its own redundant power supply, separate water-tight and dust-free enclosures for the LEDs and control electronics that are convection cooled, USA Signal Technology LCS have a greatly extended operating life. For these reasons, USA Signal Technology is able to warranty its LCS for an unprecedented 5 years.

Texas is the first of many populous states that have expressed a need for USA Signal Technology's Intelligent LCS.
