Abstract: Managing the daily operations of Boston's Central Artery/Ted Williams Tunnel project requires integrating a variety of hi-tech systems to ensure efficient traffic flow. The Integrated Project Control System that Transdyn Controls, Inc., Pleasanton, Calif., developed for the project includes a variety of detection, messaging and security systems. These systems, the project's eyes, nose and sense of touch, are managed from a control room by a redundant computer network that prioritizes information before it reaches the operators. Upon detecting incidents, the network's expert system generates a response plan that consists of the automatic and manual actions required to correct the condition. By forging the project's vastly different control systems into a common one, the system enables the staff to approach traffic control from a high-level perspective, providing the public with a safer, more efficient, highway and tunnel.
