Automatic train operation systems: A survey on algorithm and performance index

This paper focuses on automatic control systems for train application. The analysis starts examining the grades of automation in train service application, and focuses on the tasks, which are typical for Automatic Train Operation (ATO) systems. After the presentation of the analytical statement of the problem, a brief survey on the more recent proposals for designing ATO systems is illustrated. The survey gives evidence to the comparison among the alternative proposals for realizing real ATO systems, in terms of algorithm and performance index.
