Abstract

The paper follows a distributed approach to railway-traffic control in large areas. Control is viewed as a resource-allocation task, and a simple priority- comparison mechanism rules local decision making. The paper addresses stability issues from a formal perspective. First, a mathematical analysis demonstrates the intrinsic method's stability in a continuous-time and continuous-space approximation. Then, in a finite-connectivity and discrete- time-discrete model, the paper shows how to enhance local-level stability by distributed implementations of deadlock-avoidance algorithms. 1 Introduction Centralized strategies generally support classical approaches to railway-traffic control by concentrating status information and decision-makin
