Abstract. We present a synchronous approach to real-time reactive programming in Lucid enriched with contexts as first class objects. The declarative intensional approach allows real-time reactive programs to manipulate both events and state-based representations of complex systems. We show the formal specification of the Train-Gate-Controller problem, a standard case study in real-time systems community, and formally verify the safety property.
