This paper presents a prototype of a secure, dependable, real-time weather-responsive system. The prototype performs two operations: 1) it accesses weather information that provides near-real-time atmospheric and pavement observations and 2) it adapts signal timing in response to inclement weather. Since this real-time control system operates in a critical infrastructure, it must be designed with built-in security and survivability mechanisms. For this purpose a software architecture is presented that uses real-time monitoring to detect precedence violations and off-nominal system execution in order to provide effective contingency management. The focus of these systems is the autonomous recognition and reaction to execution patterns that have not been previously observed and thus fall outside of the known behavior. Because the described system has very similar requirements to other traffic control applications, it serves as a milestone in the development of secure and dependable real-time traffic control systems.
