The generalized railroad crossing: a case study in formal verification of real-time systems
Constance Heitmeyer, Lynch · 1994
A new solution to the generalized railroad crossing problem, based on timed automata, invariants and simulation mappings, is presented and evaluated. The solution shows formally the correspondence between four system descriptions: an axiomatic specification, an operational specification, a discrete system implementation, and a system implementation that works with a continuous gate model.>
