Abstract:
The emergence of new flexible passenger transport services enabled by technological advancements can have substantial impacts on efficiency and sustainability of public transport systems. Socio-economic appraisal methods of transport investments have developed during last decades, and especially CBA is proven to provide robust method for ranking alternative large conventional transport investments such as rail and road projects. However, there is much more uncertainty with potential impacts of new flexible passenger transport serves such as the automated demand responsive transport services, which can be seen as disruptive technologies on the transport markets. For addressing this uncertainty, we studied governance practices for using CBA and other economic appraisal methods in public decision making in the European Union with a special focus on Germany. We identified and analysed the most uncertain and challenging impacts of the new flexible transport services, which require better consideration in current evaluation methods and practices. The results point out challenges and opportunities for reaching the gap between current appraisal practices and the latest knowledge on the potential impacts of new flexible passenger transport services.
