Kurzfassung englisch:
Selecting the proper transport system for implementation in urban public transport networks is a complex field of decision-making. In order to achieve rational decision-making, different options have to be compared by uniform decision criteria.
This paper gives a brief overview of available transport systems and their characteristics. Subsequently, decision criteria, which are meant to be taken into account in the decision making process are identified. The presented transport systems are investigated for their performance regarding these criteria. Furthermore, the ideal decision making process is defined and tools for comparing different solution alternatives, whilst taking the previously defined criteria into account are investigated. These items are discussed, based on literature review and expert interviews on real and ongoing decision-making processes.
The results show that there are many decision criteria that affect third parties who are not directly involved in the decision-making process. These are known as external effects and these criteria are often non-monetary parameters. That is why multi criteria analysis turns out to be the most suitable for comparing solution alternatives since they are not dependent on solely monetary values. A comparison between target and actual decision-making processes shows, that in reality political preferences of decision makers divert actual processes from the "ideal" decision-making process.
Therefore the ideal decision-making process is defined in theory and is compared to actual decision making processes, based on two case studies in Austria. A comparison between target and actual decision-making, a discussion of the results and an answer to the posed research question conclude the paper. Finally, an outlook on future questions raised during the work on the paper is given.
