PLATFORM aims at integrating social sustainability into infrastructure planning decision making, considering community needs, equitable accessibility and polycentric design that enhances social participation. As EU policies underline, social impacts and interests of local authorities and civil society affected by a common project should be taken into account to prevent conflicts. In this policy framework, PLATFORM fits between a strategic development and the exploration, as the awareness needs to be aroused and new methodologies and tools developed, to pursue a bottom-up driven approach. The main output will be a transnational awareness platform, developed and presented in a final meeting and exhibition (ME/EX) showing in an inclusive and interactive way project results and developed tools, i.e. didactic tools, seminars/webinars and proposals for the future, also available in a support documentation. The platform will therefore have a physical product and be a discussion virtual place.
