Abstract [en]

With increasing traffic congestion problems in bigger cities, it is becoming more and more important to provide the traveller with correct information about all transport alternatives. When doing that, the traveller gets the opportunity to make the best decision based on the current traffic situation. Instead of traditional travel planners, where public and private transport modes are presented separately, the co-modal travel planner offers a combination. In order to make the comparison correct and fair, the travel times have to be estimated realistically and on equal basis. This master thesis focuses on how to estimate travel times in the city of Stockholm for journeys by cars, public transport, bicycles and also for walking.

An investigation of the available data on maps and travel times shows where the currently used methods are lacking. The aim has been to recommend suitable estimation methods, calculation algorithms and ways to present the travelling times in order to achieve comparability. The conclusion is that, initially, expected times must be calculated, even though the long-term goal is to develop a real time travel planner. Car travelling times are the most complex to estimate, concerning both methods. Cycling and walking are treated as unaffected by rush hour and real time updates.

Also the presentation of the travelling times is of great importance to offer a fair comparison. Clarity of which part of the travelling time that is included, highlighting of the uncertainty of estimated times and transparency of what algorithms and methods used for calculations are recommended.
