Sustainable transport planning: Economical and morphological thresholds

The aim to reach net-zero GHG emissions from human activities by 2050 in Europe is a priority and with the Recovery and Resilience Plan a large amount of funding will be devolved to new infrastructures and to new sustainable transport modalities. In this framework, the car-dominant model has to be transformed into a multimodal one. In this paper, we analyze European urban transport policies and the widely spread tools used to evaluate infrastructure and mobility programs. Our goal is to propose a complementary methodology, based on the threshold concept, to assess the mobility project in the initial phase. A step-by-step methodology that filters design options against territorial (morphological and social) and economic thresholds.
