Kaban: A Tool For Analysis Of Railway Capacity
Author(s)
J. Ekman
Abstract
The capacity analysis tool Kaban aims at being efficient for examining if planned
infrastructure meets the expected need for railway capacity. Infrastructure, safety
rules, signalling and traffic are all modelled in great detail in Kaban and hence
the tool is a useful support for signalling design. The tool is also useful for finding
out which routing and what train order suits existing or planned track layout.
The idea of Kaban is that traffic patterns can be modelled as discrete event systems,
with the minimum cycle time as a capacity measure. This measure answers
the question if a certain timetable is possible at a station and tells how much
buffer time there is. Kaban also presents results on what is critical for the capacity,
aiming at explaining how to adjust to increase capacity. The GUI of Kaban
displays the infrastructure and train paths and takes care of the user interaction.
The development of Kaban is supported by the Swedish Transport Administration
(Trafikverket).
1 Introduction
Kaban aims at being a user-friendly capacity analysis tool, efficient to work with
and producing relevant and dependable results. Kaban aims in particular at supporting
signalling design, but the tool is useful also for other phases of building
and utilising the railway. The computations of capacity in Kaban are analytic. The
tool is based on the methods presented in [1] and [2].
1.1 The goal of capacity analysis
In this paper the point of view is that analysis of railway capacity is conducted
with the aim of supporting decisions on how to most efficiently build and utilise
