Based on collected data of 45 European demonstration projects for new propulsion systems and transport concepts within the project urban transport options for propulsion systems and instruments for analysis (UTOPIA), an analysis is performed with regard to factors that can be related to the success of these demonstration projects. Success rates are distinguished with respect to technical, economic, mobility and environmental aspects, and with respect to specific project objectives. Correlation between project characteristics and success items are used to formulate hypotheses, which are tested in a multivariate Logit analysis. The results show that the success of demonstration projects for new propulsion systems and transport concepts is positively affected by the use of more developed technologies, the use of transport modes that are independent of transport chains, using them at short distances, involving manufacturers as partners within the project and by a lack of governmental, political and environmental barriers for the introduction of the demonstrated new transport concepts. In addition the results show a trade-off between environmental and technical success. (Author/publisher)
