MODCOMP Delivers New, Open Architecture SCADA Traffic Control System to Virginia Tunnel Facility

State-of-the-Art System Provides Easy Upgrades, Low Cost Solution

June 21, 1999, Ft. Lauderdale, FL -- MODCOMP, Inc., a subsidiary of CSP Inc. (NASDAQ: CSPI), has delivered a new traffic control system to the Virginia Department of Transportation's (VDOT) Hampton Roads Bridge/Tunnel facility. MODCOMP provided professional services to integrate, install, test and deploy the new Supervisory Control and Data Acquisition (SCADA) traffic control system that controls approximately eleven miles of Interstate 64 through the Tidewater area. Parallel operation of the new and the existing systems allowed continuous operation, bypassing any extended downtime. Cost of the new system was under $900,000.

The new traffic control system monitors traffic flow; detects, reports, and responds to traffic emergencies. A new graphical interface (GUI) replaces a push button console style operator interface and allows all traffic control devices to be monitored and controlled. Operators can quickly respond to emergency situations by accessing a menu of traffic control plans. The system automatically responds to emergencies, and operators can control variable message signs and signals and obtain various status reports.

The state-of-the-art system, operating in a distributed network architecture and supporting multiple modes of operation, replaced a minicomputer control system. Commercial-off-the-shelf (COTS) enabler software products were used for the SCADA portion of the project. For enhanced reliability, a new map board containing all solid state indicators was installed in the control room. The new system interfaces with existing legacy signal controllers via custom intelligent modems developed by MODCOMP.

Delivery of the new system was on time and on budget with no cost overruns because of a close working relationship between MODCOMP and VDOT engineers. "This business relationship permitted technical issues to be addressed and solved quickly, keeping the project moving forward. We had the same goal in mind -- a state-of-the-art system. Working together, that's exactly what we achieved," according to Morris Pearson, VDOT project manager.

MODCOMP's use of COTS products was another factor in producing the system on time and on budget. "When we started the project, we decided not to write software that we could purchase. For modules that we had to build, we used industry standard tools and techniques," stated Frank Roark, MODCOMP's project engineer.
