Timed Automata Semantics of Spatial-Temporal Consistency Language STeC

Intelligent Transportation Systems (ITS) are a class of quickly evolving modern safety-critical embedded systems. Dealing with their growing complexity demands a high-level formal modeling language along with adequate verification techniques. STeC has recently been introduced as a process algebra that deals natively with both spatial and temporal properties. Even though STeC has the right expressive power, it does not provide a direct tooled support for verification. We propose to encode STeC specifications as Timed Automata to provide such a support and we illustrate our transformation strategy on a simple example.
