• What does the customer want?
• High quality service
• Low tariff
• Correct travel information
• Short travel times
• No delays
• High seating probability
• High frequencies
• Many direct connections
• ...

12

• Conflicting objectives
• Short travel times require
• high speeds
• few stops
• many direct connections
• many guaranteed connections

• do not fit with high frequencies

• require long lines and many stops
• long lines are bad for the punctuality

• are bad for the punctuality as well
• inefficient utilization of the infrastructure

• Final remarks
• Timetables are evaluated along several
  dimensions
• Hence the optimal timetable does not exist
• Capacity of the infrastructure is a bottle-neck
• Every advantage has a disadvantage
• Currently, most plans are composed mainly
  manually
• Planning can be supported by mathematical models
