Abstract
Tomorrow's train traffic systems must be able to handle more frequent traffic, higher speeds and different companies operating on the same infrastructure. Improving train traffic control can be a cost-efficient way to improve punctuality and increase utilization of rail infra-structure. The main objective of this paper is to describe a new control strategy, and a prototype system derived from basic research. By shifting the control paradigm to a high-level control strategy, many of today's problems can be avoided. The main goal for the traffic controllers will be to ensure that there always exists a valid plan for the train traffic. This plan can be executed by an automated system.
