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 • ...
Conflicting objectives • Short travel times require: • high speeds • few stops • many direct connections • many guaranteed connections • do not fit with high frequencies • requirelonglines 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 • . . . .
