2 Distributed Resource Allocation Model and Protocol

The distributed railway signalling can increase networks capacity (as trains could run closer), improve systems agility to delays and possibly reduce repair costs. On the other hand, an increased system complexity and a safety-critical (SIL4) nature requires the highest level of safety assurance. In order to apply formal methods one must clearly state system requirements and specifications. In the following subsections we describe an abstract model of the distributed railway system and its requirements as well as the of the distributed protocol, which guarantees the safety and liveness of the distributed system.
