MODCOMP Awarded Contract by Virginia Department of Transportation -- Traffic Control System Replacement for the Hampton Roads Bridge Tunnel

July 6, 1998, Ft. Lauderdale, FL -- MODCOMP, Inc., a subsidiary of CSP Inc. (NASDAQ: CSPI), announces that the company has been awarded a contract in excess of $800,000 by the Virginia Department of Transportation (VDOT) to upgrade and retrofit the Hampton Roads Bridge Tunnel traffic control system. MODCOMP will integrate, install, test and startup the new system at the traffic control center located on the North Island of the Hampton Roads Bridge Tunnel. Completion of the project is expected by early 1999.

The new traffic control system will replace the existing TOMAC application software package and the map board display system in the control room. All of the functions of the existing package will continue to be performed but will operate on a Microsoft Windows NT server-based network. MODCOMP's solution includes custom interfacing to existing systems allowing VDOT to retain part of their original investment.

"We are planning to provide an almost seamless transition from the existing system to the new system," stated Michael Duvall, MODCOMP Manager, Process Control and Data Acquisition Sales and Marketing. "This cut-over technique will bypass the traditional down time for system replacement, which is important for any continuous operation."

"We determined that a non-proprietary SCADA installation would provide the most easily upgradeable, lowest cost solution," stated Morris Pearson, VDOT Project Engineer. "Although we examined proposals from competitive companies, MODCOMP provided us with a very comprehensive proposal and the lowest cost solution."

Traffic monitoring and controlling features also will be enhanced. The system will detect and report traffic incidents and respond to traffic emergencies. Through an interactive computer environment, operators can control traffic signs and signals and obtain various effectiveness and status reports. Operator displays provide multiple screens for each mode of operation.

"Overall, the traffic control system will be optimized to achieve maximum speed of execution for the symmetrical multiprocessor CPU configuration of the servers," continued Duvall. "The system's design minimizes network bandwidth utilization, provides real-time traffic control system displays, enables bi-directional data communications and controls of all traffic control devices." The system will provide once per second map board updates and high-speed (40 times per second) data acquisition scanning of all loop detectors.

The new system consists of a 100 Mb Ethernet LAN of networked Intel Pentium¨-based computers functioning as operator workstations, central database servers, loop detection, field communications, map board control and a Graphical Traffic Information System WAN server. Database servers will run Microsoft's SQL Server and will function in a primary/secondary mode of operation.The servers will maintain synchronized databases and will provide hot backup capability.

The new traffic control system also will include Intellution's FIX and Paradym-31 COTS (commercial off the shelf) enabler software products. Together, these packages will be used for the SCADA portion of the project. The Loop Detector computer system will be constructed using Intellution Paradym-31 that schedules I/O scans of up to 10,000 times per second, allowing accurate scanning of the loop detectors data every 25 milliseconds. The data will then be processed to check for chatter, generate volume, occupancy, and speed for one second data and 15 second totals.

The servers will receive and store traffic control system state change commands from operator workstations, send the current state command for each traffic control device, accumulate traffic data for each control device, store and execute a minimum of 150 traffic control plans, and support the compilation and generation of historical reports.
