An Example for the Functionality of LinTim
Using a small example, we show the possible usage of the available functions in LinTim.
As a problem instance we use a small network, consisting of 8 stations and 8 connections - the so-called Public Transportation Network
. This can additionally be adapted by using stop location algorithms.
Calculating the Line-Concept
For this network lines
are established that satisfy passenger demands with as low
costs as possible.
Calculating the Timetable
The thus created network becomes rolled out to a time-expanded graph, the Event-Activity-Network
. A periodic timetable
can now be calculated.
Calculating the Vehicle Schedule
The created timetable can afterwards be rolled out to the whole day such that we can create a vehicle schedule. For this,
the different routes of the vehicles are determined, i.e., the specific lines each vehicle has to cover.
The computed timetable (including the vehicle schedule) is then tested for its robustness against delays. In order to do so, random delays are created and the timetable gets
adjusted. Which stations are especially susceptible to delays? The red color indicates where we have to expect trouble!
