Sustainable transport planning: Economical and morphological thresholds

Abstract

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 modality. In this framework the car-dominant model has to be transformed in a multimodal one. In this paper we analyse European urban transport policies and the widely spread tools used to evaluate infrastructure and mobility programmes. 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.
