L'évaluation socio-économique des infrastructures de transport : enrichir les approches du développement territorial
2007
International audience; Dans les années récentes, en France, le processus décisionnel en matière de grands équipements a sensiblement évolué, débouchant sur des réponses institutionnelles en termes de procédures adaptées. Ceci a eu pour conséquence d'accroître l'exigence informationnelle destinée à alimenter les débats, éclairer les problématiques abordées, leur donner un contenu le plus objectivé possible. L'une des principales thématiques systématiquement abordées dans le cadre de ces procédures participatives, est celle du développement territorial, dont l'importance en fait un des éléments essentiels de l'acceptabilité sociale. Les enseignements des observatoires socio-économiques autor…
Cultivating a ‘Digital Jungle’ : Toward a Hybrid Governance Perspective on Infrastructure Evolution
2020
Digital infrastructures (DIs) evolve rather than following planned development trajectories. We know this phenomenon as drift, that is, infrastructures drift from management control. Infrastructure drift has motivated research into infrastructure governance recognizing two governance approaches: top-down and bottom-up. Yet, what happens if an organization engaging in its digital transformation expands its DI following top-down governance while simultaneously introducing elements of bottomup governance? We study how an industrial manufacturer expanded its DI for collaboration top-down while also giving employees leeway for bottom-up governance. As a result, it found that its digital collabor…

LCA of Different Construction Choices for a Double-Track Railway Line for Sustainability Evaluations
2023
The international commitment to achieve carbon neutrality in the next few decades has oriented human activities towards the preservation of natural and non-renewable resources. In this context, a great research effort has been devoted to the search for sustainable solutions for the infrastructure construction sector, based on a thorough assessment of the environmental impact (EI). In this regards, Life Cycle Assessment (LCA) is considered one of the main components of Environmental Impact Assessment (EIA) and, for a comprehensive analysis, all the costs incurred by stakeholders during the useful life of the infrastructure should also be taken into account, applying the Life Cycle Cost (LCC)…
Aree verdi storiche e alberi monumentali: stimolo per un'efficace pianificazione delle infrastrutture verdi
2020
This study is based on the assumption that existing urban green areas can play a significant role in giving a boost to the effective development of linear infrastructures when conceived as green-blue corridors, capable to significantly affect in the production of the ecosystem services within the urban environment. The first phase of analysis, necessary to frame the case study, identified in the city of Palermo (Italy), the research focused on the ecological and social aspects of urban green, investigating its current values and potentials. The existing private and public parks and gardens have been combined with major areas of ecological relevance, whereas the monumental trees connect gree…
