Linear transport infrastructure – roads and railways – continues to represent a strategic pillar for economic development, territorial connectivity and the competitiveness of production systems. Within contemporary mobility policies, these works are often celebrated for their ability to reduce distances, increase travel speeds and ensure access to markets and services. However, precisely because of their pervasive and transformative nature, they are also among the main factors of systemic pressure on the most vulnerable territories, particularly in peri-urban and rural areas (Bonomi, 2014; Secchi, 2005). The dominant design approach, based on standardised technical parameters and a performance-based logic, tends to overlook the ecosystemic, settlement and social complexity of the places crossed (Dematteis et al., 2001). This results in a sectoral rationality that prioritises functional efficiency at the expense of ecological balance, social relations and landscape quality. This approach, often disconnected from context, contributes to territorial fragmentation, loss of biodiversity and the spread of forms of spatial injustice (Blondel et al., 2019; Steiner et al., 2013). Yet roads are not just technical infrastructure designed to facilitate movement: they are complex devices capable of modifying, constructing and narrating the landscape (Magnani, 2005). Linear infrastructure – far from being a neutral element – behaves like a relational system, capable of preserving and sustaining the forms of life, characteristics and dynamics of the places it crosses. It takes the form of an articulated structure made up of routes, lines, intersections and spaces of various kinds and scales, designed to accommodate and orchestrate different modes of interaction between people, environments and functions (Marshall, 2005). The road thus becomes the backbone of a broader territorial system, capable of generating multiple uses of the land, weaving connections between biophysical elements, and accompanying and regulating ecological processes. It is also a potential space for expression and communication, where rest areas, ramps or overpasses can be transformed into visual and narrative sequences, capable of making the landscape traversed recognisable and memorable (Annunziata et al., 2018; Augé, 2007). In this context, road space is presented as a defined but porous area, whose margins are places of exchange between infrastructure and context, points of interaction between functional networks and territorial structures. Here, a continuous system of landscapes is constructed, a web of connections that can mend fractures and restore coherence to disjointed territories. The aim of this chapter is to question the rationality of infrastructure design in light of these issues, analysing how the standards, criteria and design logic of linear transport infrastructure influence not only functional performance, but also the form and quality of the landscape. It is a question of exploring the tensions between efficiency and context, between regulatory rigidity and territorial adaptability, in an attempt to identify design models capable of restoring infrastructure to an active role in the construction of the territory and the contemporary landscape.
Le infrastrutture lineari di trasporto – strade e ferrovie – continuano a rappresentare un pilastro strategico per lo sviluppo economico, la connettività territoriale e la competitività dei sistemi produttivi. All’interno delle politiche di mobilità contemporanee, queste opere sono spesso celebrate per la loro capacità di ridurre le distanze, aumentare la velocità degli spostamenti e garantire l’accesso ai mercati e ai servizi. Tuttavia, proprio per la loro natura pervasiva e trasformativa, esse sono anche tra i principali fattori di pressione sistemica sui territori più vulnerabili, in particolare nelle aree periurbane e rurali (Bonomi, 2014; Secchi, 2005). L’approccio progettuale dominante, fondato su parametri tecnici normati e su una logica prestazionale, tende a trascurare la complessità ecosistemica, insediativa e sociale dei luoghi attraversati (Dematteis et al., 2001). Ne deriva una razionalità settoriale, che privilegia l’e!cienza funzionale a scapito degli equilibri ecologici, delle relazioni sociali e della qualità paesaggistica. Questo approccio, spesso disgiunto dal contesto, contribuisce alla frammentazione territoriale, alla perdita di biodiversità e alla diffusione di forme di ingiustizia spaziale (Blondel et al., 2019; Steiner et al., 2013). Eppure, la strada non è soltanto un’infrastruttura tecnica destinata a garantire lo spostamento: è un dispositivo complesso, capace di modificare, costruire e raccontare il paesaggio (Magnani, 2005). L’infrastruttura lineare – lungi dall’essere un elemento neutro – si comporta come un sistema relazionale, in grado di preservare e sostenere le forme di vita, i caratteri e le dinamiche proprie dei luoghi che attraversa. Essa si configura come una struttura articolata fatta di percorsi, linee, intersezioni e spazi di varia natura e scala, pensati per accogliere e orchestrare diverse modalità di interazione tra persone, ambienti e funzioni (Marshall, 2005). La strada diventa così la spina dorsale di un sistema territoriale più ampio, in grado di generare usi plurimi del suolo, di tessere connessioni tra elementi biofisici, di accompagnare e regolare i processi ecologici. È anche spazio potenziale di espressione e di comunicazione, dove le superfici di sosta, le rampe o i sovrappassi possono trasformarsi in sequenze visive e narrative, capaci di rendere riconoscibile e memorabile il paesaggio attraversato (Annunziata et al., 2018; Augé, 2007). In questo quadro, lo spazio stradale si presenta come un ambito definito ma poroso, i cui margini sono luoghi di scambio tra infrastruttura e contesto, punti di interazione tra reti funzionali e strutture territoriali. Qui si costruisce un sistema continuo di paesaggi, una trama di connessioni che può ricucire fratture e restituire coerenza a territori disarticolati. Scopo del presente capitolo è interrogarsi sulla razionalità del progetto infrastrutturale alla luce di questi temi, analizzando come le norme, i criteri e le logiche progettuali delle infrastrutture lineari di trasporto influenzino non solo le prestazioni funzionali, ma anche la forma e la qualità del paesaggio. Si tratta di esplorare le tensioni tra efficienza e contesto, tra rigidità normativa e adattabilità territoriale, nel tentativo di individuare modelli progettuali capaci di restituire alle infrastrutture un ruolo attivo nella costruzione del territorio e del paesaggio contemporaneo.

Abstract
Linear transport infrastructure – roads and railways – continues to represent a strategic pillar for economic development, territorial connectivity and the competitiveness of production systems. Within contemporary mobility policies, these works are often celebrated for their ability to reduce distances, increase travel speeds and ensure access to markets and services. However, precisely because of their pervasive and transformative nature, they are also among the main factors of systemic pressure on the most vulnerable territories, particularly in peri-urban and rural areas (Bonomi, 2014; Secchi, 2005). The dominant design approach, based on standardised technical parameters and a performance-based logic, tends to overlook the ecosystemic, settlement and social complexity of the places crossed (Dematteis et al., 2001). This results in a sectoral rationality that prioritises functional efficiency at the expense of ecological balance, social relations and landscape quality. This approach, often disconnected from context, contributes to territorial fragmentation, loss of biodiversity and the spread of forms of spatial injustice (Blondel et al., 2019; Steiner et al., 2013). Yet roads are not just technical infrastructure designed to facilitate movement: they are complex devices capable of modifying, constructing and narrating the landscape (Magnani, 2005). Linear infrastructure – far from being a neutral element – behaves like a relational system, capable of preserving and sustaining the forms of life, characteristics and dynamics of the places it crosses. It takes the form of an articulated structure made up of routes, lines, intersections and spaces of various kinds and scales, designed to accommodate and orchestrate different modes of interaction between people, environments and functions (Marshall, 2005). The road thus becomes the backbone of a broader territorial system, capable of generating multiple uses of the land, weaving connections between biophysical elements, and accompanying and regulating ecological processes. It is also a potential space for expression and communication, where rest areas, ramps or overpasses can be transformed into visual and narrative sequences, capable of making the landscape traversed recognisable and memorable (Annunziata et al., 2018; Augé, 2007). In this context, road space is presented as a defined but porous area, whose margins are places of exchange between infrastructure and context, points of interaction between functional networks and territorial structures. Here, a continuous system of landscapes is constructed, a web of connections that can mend fractures and restore coherence to disjointed territories. The aim of this chapter is to question the rationality of infrastructure design in light of these issues, analysing how the standards, criteria and design logic of linear transport infrastructure influence not only functional performance, but also the form and quality of the landscape. It is a question of exploring the tensions between efficiency and context, between regulatory rigidity and territorial adaptability, in an attempt to identify design models capable of restoring infrastructure to an active role in the construction of the territory and the contemporary landscape.| File | Dimensione del file | Formato | |
