  1. Quantitative Methods to Evaluate Timetable Attractiveness RAILZürich 2009 Bernd Schittenhelm, Technical University of Denmark & Rail Net Denmark

  2. Motivation • Development of a multi-criteria timetable attractiveness objective function - e.g. to use for timetable generation • Quantitative methods for fast evaluation of and easy comparison of candidate timetables

  3. Outline Present quantitative evaluation methods for the following attractiveness parameters • Timetable structure • Timetable complexity • Travel time • Transfers • Punctuality & reliability ----------------------------------- • Timetable Attractiveness Index • Conclusion & further research

  4. Timetable structure

  5. Timetable structure [Source: Liebchen 2006]

  6. Timetable structure

  7. Timetable structure

  8. Timetable complexity Timetable complexity is characterized by the existing interdependencies in a given timetable

  9. Timetable complexity

  10. Timetable complexity

  11. Timetable complexity

  12. Travel time

  13. Travel time

  14. Train transfers p = minimal interchange time h = minimal headway d = planned dwell time p = h + d

  15. Punctuality & reliability

  16. Timetable Attractiveness Index

  17. Conclusion & further research • Preliminary quantitative evaluations methods for the following timetabling issues - Timetable structure - Timetable complexity - Travel time - Transfers - Punctuality and reliability • Quantitative evaluation indexes need further research / refinement to improve each index individually and the general timetable attractiveness index e.g. identification of preferred national timetable structure by conducting interviews and implement results in a multi-criteria analysis • Creation of a multi-criteria objective function for timetable generation
