OpenTimeTable (OTT) allows multifold illustrations of operational data and the computation of corresponding key indicators. By means of statistical analyses the user is enabled to draw conclusions on possible enhancements of the timetable. For example reoccurring delay propagations become evident and planning parameters can be monitored for their in-field suitability. Beside the evaluation of real world data, OTT can also be applied to illustrate simulation results achieved by LUKS® and can though accompany the whole planning process of timetables. OTT requires no infrastructure data but solely recorded or simulated traffic data.

The first version of OTT was developed by a collaboration of Swiss Federal Railways SBB and ETH Zurich. In 2007 Swiss Federal Railways SBB reprogrammed OTT in Java and is continuously adding new functionalities. Since 2012 VIA-Con acts as distribution partner to enable the use of OTT to other companies.

OTT is applied by more than 100 users at Swiss Federal Railways SBB. Furthermore, OTT was introduced at German DB Netz AG, Austrian Railways ÖBB and Israel Railways.

Graphical Timetable
  • Visualisation of train runs in a time-distance diagram

  • Big variety of display options (planned path, daily runs, median, cover, etc.)

  • Colored median according to a deviation from planned path

  • Customisable color schemes

  • Details of displayed trains are listed in the Raw Data Browser

Graphical timetable diagram
Corridor Analyser
  • Provides the identification of route sections with peculiarities

  • Highlighting of deviating trains in a time-distance diagram

  • 10 analytical criteria for selection (departure delay, arrival delay, dwell time excess, etc.)

  • Threshold values can be set individually per analytical criterion

  • Details of threshold exceeding trains are listed per analytical criterion in the Corridor Analyser Data Browser

Corridor analysis
Statistical Analysis
  • Various aspects of traffic data can be statistically evaluated and displayed in diagrams

  • 6 analysis criteria and 2 combined criteria are offered (arrival delays, departure delays, dwell times, journey times, etc.)

  • 3 diagram types are available (histogram, boxplot and lines)

  • 14 evaluation categories are available (time, stations, traintype, trainfamily, trainnumber, track, etc.)

Connection Diagram
  • Check of connection quality in stations

  • Determination of success rate of fetching connection trains within a defined connection time and a defined connection window

  • Evaluation of single arriving trains or a complete station

  • Details of success rates of all arriving trains of a station are gathered in a list

Connection diagram
Track Occupancy Diagram
  • Check of planned and actual track occupations in stations

  • Visualisation of track occupations over time in a histogram per track

  • Occupation ratio indicates how often a track was occupied during a time interval

  • Occupations of different track numbers can be merged in one diagram

  • Color of histogram bars selectable by train types, occupation ratio or number of trains
