Train Scheduling and Simulation
Abstract
In this report we will discuss some
aspects of Train Scheduling and Simulation. Pre- vious work is limited to
scheduling of trains on sections having atmost two lines. We will discuss the
algorithm that was used to schedule trains on two-lines.
We will discuss the
changes made to the algorithm to simulate train-scheduling on three-line
section. This report describes the work done to make effective use of the third line in scheduling of the trains. The changes in
algorithm are required in such a way that they may be extensible to sections
having any number of lines. We will also discuss my work on handling test
cases.
The previous work done in this regard is
capable of doing fairly detailed simulations of trains; it models tracks,
signals and signalling protocols, locomotives and their dynamics
characteristics (i.e. acceleration/velocity that they are capable of). It is
able to give a graphical output of the various locations of trains at various
points of time. It provides information regarding the block occupancies and
loop occupancies.
It is related to scheduling of trains on one-line section.
The single line is used in both directions, namely up and down directions. The
previous application can also handle train scheduling on sections having two-lines.
Each line is reserved for one particular direction, namely the up direction and
the down direction. The trains are scheduled on rst-come-rst-serve basis. This strategy is not the optimal strategy since it gives no
consideration to the pipeline effect.
Project Specifications
The application was to be further developed to
be able to schedule the trains on a three-line section. The three-line section comprises of two dedicated railway lines: one reserved
for up direction and other for down direction. The third line can be used in
both the direction. We need to understand how to use this third line.
We need to be able to
determine the direction in which the third line needs to be used during the
various intervals of time. Test cases for 3-line sections were to
be designed and tested. Scheduling strategies for effective use of the third line were to be determined.
