What do our cities need? Let’s think for a second to a street. With shops and benches, and people walking to their favourite grocery store, to the café right around the corner. Two students are waiting at the bus stop and chatting. An old man is sitting on a bench watching other people going back and forth down the streets, just for the sake of it. There is a guy parking his bike and tying it to a streetlamp, while the postman is getting ready for its next delivery. Two girls are crossing the street on the zebras to reach that fancy shop on the opposite sidewalk, eating an ice-cream they just bought in their favourite ice-cream factory, two blocks away. All those people have almost nothing in common, if not for the fact of being all outside their houses, all sharing the same space for many different reasons. Now let’s imagine the same thing, let’s say, in a commercial district. You still do have a street and in some cases you do have bus stops and sidewalks you want. But that lively frame that we pictured before here is almost impossible to see. What is missing? What changed? There is something have. According to Jan Gehl we move in the outdoor space for three main grocery store, we have to take a bus to go to work… it all includes those activities which, to be exploited, require to go outside our homes and

reach different points in space, crossing the public realm. The second reason is for pleasure. Standing on the riverfront to enjoy the sunset, reading a book lying on the grass of the community park. In any city you can experience the needs to connect to the public realm to satisfy their basic needs. But how do they do the basic things, how much time do they spend voluntarily outdoors, it greatly depends on the physical environment they are surrounded by. The city is the stage of our lives, of our everyday experience: if it is a good stage, the show will be much more enjoyable. The last reason why we meet in the public realm, is to socialize: this doesn’t mean making new friends, the level of interaction can be very reduced indeed, even indirect or passive. And to achieve this kind of informal contact between people, the environment of this socialization needs to be safe and vital at the same time. Users and inhabitants have to be able to feel free to choose to stay or to go, to socialize or not. Our life is made of choices, which grocery store to go, where to have a haircut, on which ATM to go to withdraw money. We move in the outdoor space to satisfy our needs but also to enjoy our day. And every person needs to feel part of his neighbourhood, of his city,

This reminds us once again the thesis of Alexander, when he described the difference between the city seen as a tree, and the city seen as a semi-lattice. And many housing estates of the XX Century are trees.
A healthy city can embrace and make productive use of the differences of class, ethnicity, and lifestyles it contains, while a sick city can not. Sick cities isolate and segregates difference, drawing no collective strength from its mixture of different people and uses.
If they would try to really connect with what is outside, they would realize that the distinction between the project and the city surrounding it will disappear. A project that really works, once completed should give the idea of having always been there, as part of the intricate puzzle of streets, facades, doors, windows, parking lots, sidewalks, girls with ice cream, cyclists and grocery stores. Traditional cities can support and take full advantage of the coexistence of elements which are

STREET. A street is a mostly open space that is publicly accessed and establishes a functional, visual and spatial link with private domains, i.e. plots, by which it is different magnitude happening at different pace. Streets tend to be the most permanent elements of all, imposing conditions to the fabric that sits on them. Streets are highly loaded with character and changing in type, meaning and value whilst penetrating the city. When allowed, they establish a functional and formal relationship with such fabric in terms of fundamental factors like density, land-use, size and geometry and accessibility of plots. Such relationships are mainly the product of the evolution of the fabric in time, being selected according to factor that constitutes the link between street and plot is centrality. CENTRALITY. Centrality is here intended as a particular character attached to streets by their geometry (i.e. length) and topology (i.e. the way they are connected to each other). Work conducted in UDSU (Porta, Crucitti, & Latora, 2006) (Porta, Latora, Wang, & Scellato, 2009) as well as elsewhere (Hillier & Hanson, 1984) (Hillier, 1996) grounded way. Subsequent work is studying the formal relationships between streets and frontages to understand patterns of change of the latter inrelation to change in the former. Studies in this line of research are beginning raising evidence on these key-relationship and, though there is a long way to go before these factors are i.e. urban morphology, and therefore likely to develop relatively quickly. STREET FRONT. Street fronts are the formation of plots facing on a street. They are the key components of urban blocks, yet their relation to streets is, in history, more direct and important. If a street fronts can adapt to a street’s character over time it makes it more versatile; if on the other hand it is linked to a whole block, its capacity to change and adapt is restricted, its lifespan shortened, with implications on character and quality of life. Street fronts are made of plots; and yet again, plots have followed in time markets and density adapting in size to the nature of the
BLOCK by streets, whose components are street fronts. We intend the urban block as a complex rather than a uniform element. Its character may vary a lot on each street front depending on the type of streets it faces upon. An ordinary urban blocks exhibits four street fronts, because it normally sits on four streets. Because streets generally possess different “importance� (main, local, secondary...) depending on This is due, again, by the evolutionary character of the ordinary urban fabric: its formation is led by streets developing in time from the most to the less central, a process which is accompanied by the subdivision of adjacent land in plots and therefore the constructions of street fronts. Urban blocks are the result of this stepped process, not its constituent unit: they are formed by the completion of this cycle of formation when it reaches the point where four streets close up in a loop and their street fronts get consequently developed. Planning strategies, especially those related with coding, should acknowledge this peculiar process by assuming that the unit of analysis and coding is the street front, rather than the block.

SMALL PLOTS. Small plots are essential. Small plots are ubiquitously present across all cases allowing a vital city to emerge and grow at any time in history. Of course plots can and must vary in size and geometry, but they can’t exceed either way beyond (indeed they are really necessary in very few cases) but they are lethal to ordinary urban spaces: because they don’t afford change in time, theyare conducive to rigid patterns of use that are inappropriate for ordinary uses. Small plots, however, Large properties can (and should) be subdivided in many small plots in order to disjointed development. PLOT-STREET RELATIONSHIP. The essential engine of urban fabric evolution in time is the relationship that links plots and streets. In practice this means three fundamental things. First: a development should never be designed block by block, but rather street front by street front. As a consequence, guiding parameters (i.e. codes) should be about setting conditions of street fronts, not of blocks. Streef fronts hence should be taken as the coding units of a new generation of formbased codes. Second: density, size, geometry and uses of a plot are largely dependent on street centrality. Therefore, understanding and managing street centrality is key, while planning a city, to drive its informal evolution. Third: wherever density grows beyond the minimal threshold, say around 2030 units per hectare (gross), street fronts are built directly on street without which are the constituent part of any dense, compact urban fabric. Blocks are nevertheless to be intended as functionally and formally linked aggregation of and must be investigated locally, but the link in itself is essential everywhere. 400-MTS RULE. presented in 2009 at CNU17 congress in Denver, USA, and then exposed in a detailed position paper the successive year (Mehaffy, Porta, Rof, & Salingaros, global communication between urban areas, linking local places with their wider spatial, economic and social context. In small villages and towns “main streets” are those that head out of the urban precinct towards adjacent villages and towns and further on to the larger regional space. Within cities, “main streets” are those city’s fabric. The evolution of cities, during the phases of growth, has always been about generating less central streets from the more central, or “main”, followed by
41
the gradual allotment and construction of the new street fronts on both sides. Major special urban functions like theatres, arenas, hospitals, city halls, libraries etc are preferentially placed at “main streets”’ crossings; ordinary functions like locations, but they may spill-off to residential districts along the more central of their service streets, or “local main streets”. “Main streets” are always the most central, and their crossings are usually 300-500mts apart, so that we have termed this fundamental feature of traditional urbanism the “400-mts rule”. Recent work conducted at UDSU, University of Strathclyde in the form of an Atlas as part of rule appears to inform all cities – both planned and self-organized – until the emergence of professional theories of Urban Design in late XIXth and early XXth centuries (Baird, Feeley, Russell, & Wong, 2010). Implications of the 400-mts rule for the theory and practice of Urban Design are many. One major implication is that we should not consider neighborhoods as geographic entities anymore, and that basing our urban models on circles of 400 mts of radius on the assumption that they represent neighborhoods, a never questioned norm of professional theories of Urban Design since Clarence Perry to the latest New Urbanist schemes, means throwing cities in the hyperspace of a lethal out of scale. DISJOINTED DEVELOPMENT. The potential of small plots to enable change and diversity gets inhibited if these are not controlled by different subjects. It is the diversity of subjects who exert control over small plots that enables change. disjointed development is a process of spatial structure creation that subjects small plots to developmental paths that are autonomous from each other, though possibly under a shared agreement on basic principles. That autonomy may be expressed in different terms from case to case, including diversity of developers, owners, renters, and designers. Though disjointed development applies to the process of land development or regeneration at the design/ creation phase, its consequences are all projected into the phase of post-design, enacting the dynamic of diversity emergence and informal participation that stands at the heart of plot-based, traditional urbanism. In other words, small plots must be coupled with disjointed development, i.e. plot control assigned plot-by-plot to different subjects, in order for informal change to start and keep happening. In this sense, disjointed development is the reverse of conventional “instant city” dynamics, which are based on making it as big as it can possibly be to take advantage of economies of scale. On the other hand, increasingly

The creation of this method stems from the awareness that urban design professionals are asked to face unprecedented challenges, which involve human habitat, economic pressure, immigration, and environmental alarm.

Very often for educational purposes many projects are brought forward without having a clear idea of how the area is or actually works. Having a clear, informed, up-to-date understanding of the area in terms of population, economy, use and environmental conditions reveals its real condition. How is the area today, who is in charge of what, who owns what, what are the critical issues and potential, what kind of environmental work is required: these are questions you need to answer to maximize the value of the area, to reveal its strategic potential and directions of development.

In everyday life, a great part of our experience in our neighbourhood is spent in places we recognise as more or less familiar. We choose a street to walk down rather than another, we go shopping in a store and not in another, we orient ourselves relying on particular landmarks, we associate These choices are mechanisms that our brains active based on our experience in the outside world. The more the experience of a place is consolidated, the more the habits tend to be repeated and bad experiences avoided. We become attached to places, we learn to reach faster and faster those we go more often. Slowly we gain a sort of mental image of where the homes of our friends, our relatives, our school, our church, our community centre are located. All of this depends on the way we interface to the space of our everyday life and the factors determining the functioning of these complex relationships have been the subject of study for geographers, sociologists, psychologists, architects and urban designers. The study of perception in urban areas is a method of analysis arising in the 60s as a new born from the discipline of human geography and psychology, which takes the name of environmental perception. book from Kevin Lynch, The image of the city, published in 1960, embedding some elements derived from the psychology of form, according to which perception involves selection and organization patterns.

Legibility and imageability We said that Character Areas are portions of space perceived as unitary. But where does this sense of unity come from? People make use of a set of references to determine out which way to go to reach predetermined destinations or to know where a place is with respect The easier it is to lay these references (boundaries,
landmarks,
nodes,
districts, paths) and orient, the greater the legibility of a place. City legibility refers to ease with which people learn about the layout of a city or an area. Of all the places that make up a city, of all the squares, streets and buildings, only a small portion is selected and becomes part of the basic structure of our orienteering in the city.

Street front assessment is aimed at understanding how simple spatial characteristics of street fronts can impact on communities and inhabitants. These characteristics range from the number of visible buildings to the continuity of the street front, from visual richness to maintenance, and many others. By mapping the quality of street frontages. It will be possible to understand possible correlations between the quality of street fronts and recursive collective behaviours.

In the traditional city the succession of urban events (squares, streets, markets) lead you from place to place. They are in some ways all easy equation to describe this sequence, due to its endless complexity. Looking at the traditional city with the metaphor of the network makes it easier to the catch real and subtle structures hidden in the apparent chaos of this organism. Networks are mathematical devices, used in describing complex, selforganised system of various nature such as social, biological, technological and economic ones. We can say that a city is network made of streets and squares, intersections and hubs, where it is possible to identify places gifted with a stronger iconic character. As part of the public realm,
those places are the stage of people’s
everyday experience. And the more they are used the more vital they are. We can call this places “centres” because they have, in people’s A centre is a place which has its own image in people’s mind in relation to other places in a city. It’s position can be geographically or just The more this image is vivid in people’s mind, the more it’s likely for those centres be the places which truly work.

The theory of centres Aware of the importance of centres in delivering better and more lively places, we are now asking on which basis can they be evaluated we evaluate it? how to determine To assess the importance of a centre or a node in relationship to others in the network, a parameter named centrality was introduced.

Transplanting the historical street pattern
Improving local connectivity In this scenario, new and more capillar connections are made across the M8, withouth altering the current path of the motorway. Streets that come to dead-ends at one side of the motorway are linked to street s on the other side. Both the M8 and the network of the city are taken into consideration to cater the demand
The city of Glasgow in 1894 was characterised by the presence of a fairly consistent, unbroken grid pattern. There was no motorway and the urban network was not cut in such a dramatic way. In this scenario, a simulation was carried out in which the network of the existing central area of Glasgow is replaced with the network as it was in 1894 and then linked to the surrounding current city as it is today. A the end of the XIX Century no motorway existed in Glasgow, so this scenario provides an insight into

how Glasgow might look like if the M8 had never been constructed. This will allow us to observe ways in which the M8 strengthens or/and weakens the network.
Betweenness centrality
Betweenness centrality Without the abundance of dead-end road and cut-off connections which are present in the existing network because of the M8 scar, the global closeness centrality of this scenario extends to a much wider range of the city than the current situation as well as any of the other scenarios.
The centrality of the city surrounding the M8 is higher in this simulation. The City Centre shows more paths with high level of betweenness, as does the ciy to the west of the motorway. Perhaps the greates improvement in centrality assessment is to the north of the M8, between the existing streets.

The area showing high level of global closeness is smaller compared to the existing city. In addition the center of global closeness is shifted towards the M8, presumably due to the new connections realised there.

The amount of
When we imagine the size of an intervention at the urban scale, we often picture in our mind a vast portion of space. However actions within the urban tissue are never limited to spatial nature of operating processes can sort very different effects: some are immediately visible (new buildings, new roads, etc.) while others are longterm and less explicit. The latter are, very often, very hard to appraise in the design phase. For this reason, any urban intervention, aiming to determine long-range portions of the city, is three-dimensional. There are physical
(the tangible change), socio-economic (groups
involved, stakeholders and policy makers, local community) and temporal dimensions. The temporal dimension can be included in the urban project in two ways. You can imagine a sneak peek into the future to se possible effects of decisions taken in the present day, studying patterns of development and trying to predict future trends, delivering what is called “vision”. Another way is to place in a more or less near future, a goal, by taking “urban photography” that describes an option for future and trace backwards what will allow, starting from today, to get to that situation at This is the idea underlying scenarios-based design, in which the temporal element has a strong preponderance and everything is designed in

Every city has a unique character and the factors that contribute to its formation are so many that it would be impossible to list them. Considering merely the morphological factor and observing how formally the urban fabric manifests we may already realize that each city presents original and typical features.

Having ignored for decades this trademark, planning methods of the last We have lost, so to speak, the matrix accompanying the growth and the incessant and spontaneous urban regeneration, in favour of a standardised and impersonal mould that tells nothing of the meaning of a place.

It is commonly argued that our suburbs all look the same: how to blame this statement? How much difference there will ever be between a tower block on the outskirts of Glasgow and one in he Parisian’s banlieux, compared to the difference that exists between the same two cities in any point of their historic core? Of course you can not, nor want to, return to Victorian houses or NeoRenaissance building to reduce the “linguistic gap ‘. also because, as it has always happened in the history of the city, the language evolves and changes with the changing of technologies, policy framework, ruling classes, tastes and habits of people.

The bulk of this work in terms of time and complexity can be very demanding, so it is strongly recommended to carry it out with a team of collaborators.

When you assign the new density, you should address to street fronts and not to blocks: this is because the attribution of the density is strongly tied to the importance of the streets bounding the block. The street-front hierarchy is dictated by by the MCA assessment. As a general rule, denser street fronts within the same block correspond to urban roads of higher hierarchy.

What will be explored in the following pages of this dissertation is the crucial theme of how to deal with growth, repair and sustainable survival of our cities applying appropriate design strategies and tools to reconnect communities severed, split, cut at a local scale by decision taken to a global scale, such as infrastructures like motorways, railways, electroducts etc. The result is that areas affected by the presence of these elements very often fall into disgrace: land value drops drastically, unclaimed land offer little incentive for use and investments, growth is retarded and weakened, although these areas, perhaps more than any other, need resolute interventions to re-establish links and stimulate uses. Aside from creating unsustainable communities and feeding suburban car-dependant sprawl, the effect of a large infrastructure on a typical urban fabric is detrimental to the city. Referring to relevant literature, international experience and by experimental work, it has been studied how to deliver urban sustainability by dealing with this massive structures with a special focus on reclaiming the city’s lost spaces.

the sizes and boundaries of urban blocks can be noticed. As we get closer to the City Centre the grid is more compact and blocks show reduced surface and higher density, more storeys per building and higher built ratio. At the same time we can see how, in the industrial areas close to the Clyde docks, the block shape tends to be thin and deep towards the river. The grid is more or less regular, adapting to terrain morphology and context conditions, successfully incorporating pre-existing historical patterns. The unbroken grid was one of the most remarkable features of denser and more vital areas in Glasgow and it set the rules of urban growth for centuries.

The motor car started to become an issue just before the Great War due to the inadequacy of the road network. Unsurfaced and largely unmaintained roads were acknowledged by the government, which set up the Road Board, a public program for surfacing and improving the roads.

on all modes, with appropriate demand management and land use strategies may be higher than previously believed. Gridded street patterns are especially effective (although the downtown Seattle grid, may be limited in its capacity for such absorption). Studies have shown that the addition of capacity can actually increase over a network. Freeway removal does not require a major shift to transit. Removal of an urban alternate routes and travelers will choose the most convenient mode for their trips or travel at different times or to different locations. Freeway removal has a catalytic effect. Excess right-of-way can often be redeveloped or converted into civic amenities such as open space. Even where this is not the case, however, the impacts of freeway removal tend to be felt over a broad area. Surrounding property values increase, neighborhoods become more attractive to investors and visitors, and crime can be reduced through increased foot perceptions of safety often change. None of the cities studied noted any long term negative economic impact, even to areas that had previously been directly served by the freeway. Design is key. It is not enough to merely replace a grade-separated roadway with an at-grade street. “Complete� street design that seeks to accommodate all
of transportation supply. Reductions of roadway capacity must be managed, mitigated and monitored over time. Freeway removal is not just a one-time demolition project. To be effective, it requires a long-term commitment and a thorough, integrated approach; one that constantly observes conditions and designs solutions for all users. Freeway removal should only be undertaken after careful consideration of trade-offs. Even under the most favorable circumstances, freeway removal is not a panacea atgrade roadways, it may prove challenging to pedestrians; to the extent that it reduces auto mobility, it may promote some types of businesses over others. In any case, a civic conversation about competing values must take place. Reduced auto mobility for some trips may be acceptable if other values, such as quality of life and economic development, are prioritized.

The size of the study area is not unintentional: the 400 metres radius buffer is crucial to analyse the local effect of the infrastructure on urban fabric, accessibility, social behaviours, soil conditions and people’s perception. It is selected based on studies applied to pedestrian movements and social dynamics which can be analysed only referring to a urban fabric surrounding the M8.

The presented proposal is to tunnel the motorway from Townhead to Tradeston, hiding the eyesore of the M8 creating high quality useable land the motorway. The inclusion of a public transport link within the tunnel will, along with the Cross-rail project, overcome the separation of the city’s two main train regional and local connections. Water drainage, gas and electricity systems will be integrated as well. There will be a reduction in the number of junctions within the City Centre will be drastically downscaled but they will manage to carry on their actual capacity. Tunnelling the motorway also presents the opportunity to enhance public transport between suburbs, promote development of city centre motorway junctions. Focus will centre on Sighthill and Port Dundas to improve conditions and reinforce opportunities.

These six neighbourhoods, each with distinctive characteristics and attributes, blocks, safe and traversable streets, central transportation links, abundant amenity centres and beautiful and intriguing design. At the heart of this regeneration plan, there are three underlying motives:
t Creating and maintaining necessary local, city-wide, regional and national transportation links:
The Glasgow bypass line will make
Glasgow a crucial part of the national train network. This new train line City subway system and an unaltered North / South bypass of the City.
t Establishing more integrated, diverse and accessible communities receive the essential local and district amenities that have been unable to survive due to the M8 coursing through the City. Proper

fatto da professori e studenti che, in uno spirito di condivisione e collaborazione continua, mi hanno permesso di raggiungere questi risultati e di scrivere questa tesi. Tutto quello che è stato descritto, analizzato e progettato, ma anche tanto altro che non è stato possibile includere, non sarebbe mai esistito senza l’attento lavoro di tutti gli studenti dell’Urban Design Studio, dei docenti e tutors della Urban Design Studies Unit della University of Strathclyde di Glasgow, UK, che hanno operato con passione ed incessante impegno per creare qualcosa di valido ed importante.

Un ringraziamento speciale ai professori Ombretta Romice, Sergio Porta e a Peter Russel,
Dulcis in fundo... Un grazie ai miei amici, sparsi qua e là, ma sempre presenti e sempre disponibili a starmi vicino, aiutarmi e ospitarmi nelle mie varie trasferte. Mi rivolgo soprattutto agli
mitici, stupendi ed appassionati: non ce ne sono di migliori.
Un grazie a Maddalena, senza la quale forse la mia avventura glaswegiana non sarebbe neanche iniziata, la prova vivente che i sogni vanno afferrati e che spesso sono più a portata di mano di quello che uno possa credere. Un giorno progetteremo ancora insieme, è una promessa. Un grazie a Matteo, per quella volta che ha affrontato sei ore di treno per cucinare un piatto di spaghetti ad una studentessa catatonica in piena anche negli sbalzi d’umore ricorrenti ad ogni esame, scadenza, revisione.
trascorrere tutti i momenti che meritiamo di vivere insieme. Grazie a mio padre, che mi ha ispirato a puntare sempre in alto, a non scendere a compromessi, specialmente mai con se stessi, a non essere mai un numero fra tanti, a credere in quello che faccio e a fare quello in cui credo. So che se fosse qui ora sarebbe orgoglioso di ciò che ho raggiunto. Grazie alla mia squarda del cuore, la mia famiglia, Grazie ai miei fratelli, Alessandro ed Emilio, lo ying e lo yang, i pianeti opposti del mio universo, i miei migliori amici. A mia madre, a cui dedico questo lavoro (e a cui devo il 50% di tutti gli altri) un grazie solo non basta: per le confessioni fatte col cuore in mano, senza nascondersi mai niente, i momenti di gioia come quelli di tristezza. Grazie per avermi messa sempre al primo posto: anche se non te l’ho mai detto, lo vedo in ogni cosa che fai, e so che non c’è amore più grande. Grazie per la forza e la caparbietà che mi hai trasmesso, ma anche per l’umiltà e il coraggio di mettersi sempre in discussione. Se c’è qualcuno che non ha mai smesso di credere in me, sei proprio tu. Spero di essere sempre la persona che tu hai cresciuto.
