Embedding “roadside equipment” into environmental assessment of transportation system: the case of safety barriers
2015
The work arises from the consideration that the environmental impact of a road cannot be limited to the analysis of its constituent materials, even if correctly analyzed in their life cycle. In fact, a given road not only consists of the pavement and subgrade, but also includes several different components and accessories (e.g. road marking, drainages, safety barriers, etc.) that contribute to set a road infrastructure in operative conditions. As a matter of fact, only limited attention has been paid in the scientific literature to roadside components, unlike pavement and traffic flow. In the present work, the environmental burden of one of these components, i.e. the safety barrier, has bee…
Liikenneinfrastruktuurihankkeiden rakentamisaikaiset vaikutukset työllisyyteen
2022
Hankkeen tavoitteena on ollut määrittää tutkittuun tietoon perustuva viitekehys liikenneinfrastruktuurihankkeiden rakentamisaikaisten työllisyysvaikutusten arviointiin. Liikenneinfrastruktuurihankkeen rakentamisaikainen bruttomääräinen vaikutus työllisyyteen muodostuu suorasta työpanostarpeesta työmaalla ja välillisestä työpanostarpeesta. Välillinen työpanostarve taaksepäin syntyy rakentamisen välituotevalmistuksessa ja välillinen työpanostarve eteenpäin palkkatulojen synnyttämän kulutuskysynnän lisäyksen kautta. Nettotyöllisyysvaikutus tarkoittaa työllisyysasteen muutosta taloudessa. Silloin huomioidaan rakentamisesta johtuvan työvoiman kysynnän syrjäytysvaikutus jo olemassa oleviin työpai…
Analiza przestrzennego zróżnicowania zmian w potencjale infrastruktury transportowej w Polsce
2015
Wiele zachodzących zjawisk, ich rozwój czy kierunki zmian, uzależnionych jest od przestrzennych interakcji pomiędzy sąsiadującymi regionami. Model przestrzennej analizy shift-share (SSSA) został wprowadzony do badań przez S. Nazarę i G.J.D. Hewingsa. Przedstawia on przestrzennie zmodyfikowane stopy wzrostu (tempa zmian) poszczególnych wariantów zjawiska przez uwzględnienie temp wzrostu zjawiska w obszarach sąsiadujących. Celem artykułu jest analiza zmian struktury infrastruktury transportowej w województwach Polski w latach 2004 oraz 2014, według rodzajów infrastruktury transportowej z zastosowaniem przestrzennej dynamicznej metody przesunięć udziałów. W opracowaniu dokonano oceny tempa wzr…
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)…
Emergency Response Model as a part of the Smart Society
2021
Centralized hybrid emergency model with predictive emergency response functions is necessary when the purpose is to protect the critical infrastructure (CI). A shared common operational picture among Public Protection and Disaster Relief (PPDR) authorities means that a real-time communication link from the local level to the state-level exists. If a cyberattack would interrupt electricity transmission, telecommunication networks will discontinue operating. Cyberattack becomes physical in the urban and maritime area if an intrusion has not been detected. Hybrid threats require hybrid responses. The purpose of this qualitative research was to find out technological-related fundamental risks …
More nature in the city
2020
According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
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…
Projet urbain et Jeux Olympiques: le cas d'Athènes 2004
2005
Beyond the international sporting event they represent, Olympic Games are also a real catalyst for urban change they cause or accelerating. Indeed, they can be seen as an organizational tool, development and equipment of the host cities who have to service all Games a range of sports facilities , transport , accommodation ... that support the effective course of the global event . 2004 marks the return of the Olympic Games on the territory where they were born ; Athens hosted the first games of the third millennium . However, the Greek capital is a framework especially since this ancient city , archaeological and architectural history so rich, is also recent capital and the diachronic prove…
Bunker culturel : la régénération du patrimoine militaire urbain à Saint-Nazaire
2011
Au cours des deux dernières décennies Saint-Nazaire a relancé son développement sans se référer nécessairement aux modèles des métropoles européennes. Concentrées autour de la zone portuaire, près de la base sous-marine allemande, les nouvelles opérations urbaines ont contribué à définir un important projet touristique et culturel. La spécificité symbolique et la valorisation du patrimoine militaire ont permis à Saint-Nazaire de montrer que l’identité d’une ville pouvait activer sa croissance.Over the last two decades, the port city of Saint-Nazaire has encouraged urban redevelopment without necessarily following the models suggested by other European cities. An important cultural and touri…
