The use of simulation in rail project development

Recent population growth has combined with an increase in mode share to stretch the limits of metropolitan rail systems in Australia. Accordingly, new infrastructure and operational changes are required to provide sufficient capacity to serve future demand. The provision of additional railway capacity is expensive. Competing government pressures means there is an ongoing need to ensure that decisions on project priorities and scope are robust and demonstrate value for money. Simulation can be a cost effective way to inform decision making because it enables predictions of future capacity provision to be made without the need to physically construct infrastructure. A range of approaches are currently used by the rail industry to inform operational decisions (operational experience, analytic desktop assessment and simulation). While desktop and analytic approaches are suitable for high-level assessment of conflict and delay free scenarios, simulation approaches are able to consider a broader range of variables and issues, they can also help to provide an objective assessment of operational performance. Accordingly, this paper outlines how a combined approach to analysis can help assist the development of rail projects by providing robust results to support decision making in a timely and cost effective manner.
