文摘

This article sets out a procedure that enables a monetary rating of conflict-resolution scenarios for train services to be conducted by coupling simulation procedures from railway operations research with mode-choice models. Such an approach has only previously been adopted for strategic network planning. Forms of conflict resolution have hitherto had no account to the implications for end-customers.

Forming the basis for monetary ratings are the delays suffered by resolved train-running conflicts. These delays are established for given train priorities using the LUKS-S software tool and serve as input variables for mode-choice models.

Delays suffered by trains influence the mode of transport selected by the end-customer. The modal split thus computed reflects demand for the rail mode and is called upon to determine revenues. Revenues are set against variable costs to form a contribution margin per train run. Changes in the contribution margin are extrapolated by comparison with delay-free timetable conditions.

How trains are prioritised impacts on the decisions taken to resolve a conflict and hence also on the ensuing delays. Forms of conflict resolution can be rated monetarily. A conflict can thus be resolved most effectively, where the change in contribution margin is minimised.
