Abstract
In this paper traffic management strategies for disruption-caused inaccessibility of one track on double-track railway lines are analyzed. Building on previous results for polling systems with \(k_i\)-limited service discipline and non-zero switchover times heuristic rules for optimally switching the orientation of the remaining track are investigated. QoS-standards enforcing delay constraints for both orientations as well as asymmetric traffic load, e.g. resulting from differing block length in both directions, are accounted for. For a system without train priorities analytical approximations as well as simulation results for the optimal switching parameter are compared. The analysis is extended to priority systems in a simulation approach. The performance of the heuristic is tested in a case study by comparing it to the optimal solution obtained by solving the train scheduling problem for the bidirectional line segment.
