This paper introduces the architecture of a large scale distributed computing system for the Area-wide Real-time Traffic Control system (ARTC). In the ARTC system, signal controllers coordinate with each other through the communication network for real-time adaptive traffic control. For reliable service, the ARTC system is designed to be fault-tolerant at the I/O component level, processor level, and the network level. A modular system architecture is proposed for the ARTC signal controllers to support fault-tolerant design strategies. A flexible, cost-effective networking strategy is presented to support different level network redundancy. In order to estimate the expected service quality of the ARTC control system and to study the reliabilty impacts of signal controller failure rate, the repair efficiency, and the degree of system redundancy, an analytical model is developed.
