Sensitivity Test of the STEM Method Modified to Prioritize the Allocation of Traffic Path Capacity

Abstract

CTU in Prague Faculty of Transportation Sciences, Department of Transport Systems, deals in its research with the issue of allocating the capacity of a railway transport path. The capacity of any transport route is a limiting element in terms of its functionality. It is not always possible to meet all requirements and the allocator has to decide how to allocate capacity, so that it is as efficient as possible and achieves as many societal benefits as possible. The research team deals with this issue by using a modified STEM (Step Method) method for its research, which is a tool for linear optimization. The article presents the use of this method on the railway line Plzeň - Žatec in the Czech Republic. It deals with its sensitivity while changing the parameter of the number of passengers in the individual segments of the passenger rail transport. There are many requirements for the allocation of railway capacity, but the infrastructure is not able to satisfy all of them. The article presents a simulation of three variants of the number of passengers expected in regional expresses. This represents the possibility of allocating capacity to different train segments in situations when the infrastructure cannot satisfy all requirements for railway capacity allocation.
