Mayoral foreword
Since 2000 the number of cyclists on the Capital’s major
roads has more than doubled – up nine per cent in the year
2008‑09 alone.
Yet this is just the start. I’m determined to turn London into
a cyclised city – a civilised city where people can ride their
bikes safely and easily in a pleasant environment. Cycling,
with all its social, environmental, health and financial benefits,
has an important role to play in the future of the Capital
p.4
What does a cyclised London mean? I believe it means
achieving 10 conditions:
~ Cycling recognised as a major transport mode right across the capital, from
central London to the outer boroughs
~ Streets and spaces where everyone respects each other’s right to use the road,
where they stick to the rules of the road, and where everyone recognises their
duty of care to other road users
~ A reduction in cycling casualties, with a particular focus on reducing the risk
of collisions between cyclists and HGVs
~ An increase in secure cycle-parking on streets, in workplaces, and at stations
and schools
~ Cycle theft tackled through dedicated police attention so people can
be confident they’ll find their bike where they locked it
~ Cycling promoted as an enjoyable, everyday, healthy activity
~ Cycling embedded into the way our city is planned and run
~ Investment in cycling maximised – from both the private and public sectors
~ Key partners working together to deliver cycling initiatives
~ New routes and opportunities for commuting, leisure and local cycling trips
But I’m not alone; this is not a lone crusade. Sixteen organisations, listed opposite,
from across the public and private sectors in London have put their names to this
vision for a cyclised London and will be instrumental in helping create the conditions
that will deliver it.

400 percent incease since 2001 needed so cycling accounts for 5 percent of all journeys
p.7
KULVEER RANGER
Mayor’s Transport Advisor and TfL Board Member
now around half a million journeys are made by bicycle
on each day.
It can help to unlock a trinity of benefits: Environmental, by encouraging modal shift
from the car to the bike for short journeys we can ease congestion and improve local
air quality; Health – this one’s a no brainer – with increased physical activity; and finally
economic benefits, shorter journeys to local shops can lead to the reinvigoration of
our high streets and local businesses.
While the London Cycle Hire scheme in central London may be perfect for nipping
about the West End, a different solution is needed for people cycling in Outer London,
visiting friends, shopping or travelling to school. In fact, an astonishing two-thirds of
the growth potential exists in Outer London where about half of all car journeys
could be cycled in just 10 minutes.
p.9
We know that there are many barriers that prevent people taking to pedal power. For
some, it’s a fear of traffic. Others simply find the car, bus or Tube more convenient.
Often it comes down to habit. We are working hard to break down these barriers and
make cycling the most convenient and obvious choice for most journeys.
Note it is London’s year fo cycling
p. 10
As a result of the increase in investment in recent years, the rise in the number of
people cycling has already been significant, with a 117 per cent increase on London’s
major roads since 2000.
The Mayor wants these benefits to be enjoyed by even more
people and is aiming to deliver a 400 per cent increase in cycling by 2026, compared
to the 2001 baseline.
Forty per cent of households in London have access to a bike, but one in five of
these are unused.
p.11
Central London – is characterised by high employment density, a significant
concentration of short journeys, limited road space and low levels of car use.
With cycling offering a faster, more pleasant alternative for getting around the
centre of London, significant growth in cycling is well within reach.
Inner London – There are many thousands of commuters from the Inner London
boroughs that use the London Underground and London’s buses to journey into
the centre of the Capital each day. For these people, the bike could provide a fast,
convenient alternative. The ambition will be to provide solutions that make the
bike the default choice for many more of these journeys.
Outer London – Successful cycling schemes show that the right incentives and
a commitment by London boroughs can transform the cycling culture in an area,
including in Outer London. Many short journeys are made by car in Outer London,
and there is significant potential to encourage some of these to switch to bike.
p.12
This year, 2010, is the Year of Cycling. It sees the launch of three major programmes
designed to turn London into a cyclised city: the London Cycle Hire Scheme, Cycle
Superhighways, and Biking Boroughs.
London Cycle Hire Scheme – To help make London a genuinely cycle-friendly city,
6,000 bikes will become available from summer 2010. These will be available for
hire at around 400 special docking stations located in nine boroughs and in the Royal
Parks 24 hours a day, seven days a week, all year round. Users will be provided with
information on times to key destinations and cycle routes from each of the docking
stations. By combining high quality bikes, convenient locations, and a quick system
for registering, the scheme is set to become a major new form of public transport
in London, delivering an additional 40,000 cycle trips per day.
Cycle Superhighways – Using improved infrastructure to give cyclists more space
and security on the carriageway and to raise driver awareness of cyclists, twelve
Cycle Superhighways are planned. These will cater for existing cycle commuters
and will also provide for those wishing to give biking to work a try for the first time.
The first two pilot routes to Barking and Merton will be ready by the summer
of 2010 and the remainder are planned to be introduced by 2015. A significant
element of the programme will be the package of home and work-end smarter
travel measures. These will be critical to encouraging take-up and continued use,
leading to an expected 120,000 cycle trips per day. In addition, cycle parking, training
and maintenance, as well as marketing and promotional support will be offered to
residents and businesses along the route.
Biking Boroughs – This will involve locally-led initiatives driven by the boroughs
to promote cycling in an integrated way with key partners such as the police,
healthcare providers, schools and workplaces. The aim is to address the barriers
to cycling
promotion, training and behavioural change, while enabling more cycle
journeys through the targeted introduction of highway improvements
p.13
Route improvements for cyclists – TfL has invested heavily in cycling
improvements on the Transport for London Road Network (TLRN), at locations such
as the Elephant and Castle Southern Roundabout and the A316 Lower Richmond Road.
p.49
The Department for Transport has also developed a voluntary initiative, the Cycle
Guarantee Scheme, which challenges businesses to become more cycle-friendly
employers. By signing up, businesses signal their commitment to making it easier
for staff to cycle to work with efforts targeted around five key pledges:
~ Storing – secure, safe and accessible bike parking
~ Changing – good-quality changing and locker facilities
~ Buying – the Cycle to Work Scheme
~ Repairing – bike repair for cyclists on or near site
~ Inspiring – training, reward and incentive programmes to achieve targets
for more cycling
TfL is working closely with schools to promote cycling, with London leading the way
in targeting a change in school travel. By the end of 2009, more than 2,700 schools
had an approved travel plan, representing 90 per cent of London’s schools. Results
have been impressive, too, with a reported 6.2 percentage point reduction in the
proportion of car use since the start of the School Travel Plan programme.
p.67
The Department of Health estimates physical
inactivity costs London’s PCTs alone at least £105m a year and new cycling
projects can directly tackle this.
By working in partnership with healthcare services TfL can help to achieve the
aims of NHS London’s ‘Go London’ campaign, to create a more healthy and active
London by 2012. In

directions for understanding the development process, they lack the capability to address a
fundamental dimension of our understanding of development processes . This is the relation
between the way actors behave in deploying resources to realise specific investments, with
which much of the real estate literature is concerned, and the broader processes which drive
the strategies and interests of the various actors involved .

‘City design is a temporal art, but it can rarely use the controlled and therefore limited sequences of other temporal arts like music.’
‘At every instant there is more than the eye can see, more than the ear can hear, a setting or view waiting to be explored. Nothin is experienced by itself, but always in relation to its surroundings, the sequence of events leading up to it, the memory of past experiences.’
‘Every citizen has had long associations with some part of his city, and his image is soaked in memories and meanings.’
p.2
‘percieved (and perhaps enjoyed) by millions of people of widely divesrse class, and character… the produce of many builders who are constantly modifying the structure.’
‘While it may be stable in general outlines for soime time, it is ever changing in detail.’ Only partial control can be exercised over its growth and form. There is no final result, only a continuous succession of phases.’

legibility ‘the ease with which is parts can be recognised and can be organised into a coherent pattern.’
‘a legible city would be one whose districts or landmarks or pathways are easily identifiable and are easily grouped into an over-all pattern.’
p.3
‘legibility is crucial in the city setting….. It is of special importance when considering environments at the urban scale of size, time and complexity…. To understand this, we must consider not just the city as a thing in itself, but the city being perceived by its inhabitants.’

p.46-48
Contents of city images can be classified into five types of elements: paths, edges, districts, nodes and landmarks
Paths – streets, walkways, transit lines, canals, railroads (‘channels along which the observer customarily, occasionally or potentially moves’)
Edges – ‘ linear elements not used or considered as paths by the observer’) boundaries between two phases: walls, shores etc. can be barriers or seam lines. Not as dominant as paths
Districts – have some common identifiable character and two dimensional form (’inside of’)
Nodes – strategic spots in a city into which an observer can enter. Moments of shift. Or concentrations – focus of a district. Cores. Can be dominant feature of image
Landmarks – building, sign, store, mountain.

Analysis start with analysis or existing form and public image of area. Conslude with series of diagrams and reports illustrating significant public images, basic visual problems and opportunities and critical image elements and element iter-relations with detailed qualities an dpossibilities for change.
Object of visual plan to strengthen public image. Could prescribe cretaion or clarification of modal points visial hierarchy of paths, establishement of thematic units fo districts. Deal with iterrelations of elements and perception in motion
p.119 ‘we need an environment that is not simply well organised but peotic and symbolic aswell. It should speak of the individuals and their complex society, of their aspirations and their historical tradition, of the natural setting, and of the complicated functions and movements of the city world.’
‘by appearing as a remarkable and well-knit place, the city could provide a ground for the clustering and organisation of these meanings and associations. Such a sense of place in itself enhances every human activity that occurs there, and encourages the deposit of a memory trace.’

p. 116 visual plan for the city or metropolitan region
Analysis start with analysis or existing form and public image of area. Conslude with series of diagrams and reports illustrating significant public images, basic visual problems and opportunities and critical image elements and element iter-relations with detailed qualities an dpossibilities for change.
Object of visual plan to strengthen public image. Could prescribe cretaion or clarification of modal points visial hierarchy of paths, establishement of thematic units fo districts. Deal with iterrelations of elements and perception in motion
p.119 ‘we need an environment that is not simply well organised but peotic and symbolic aswell. It should speak of the individuals and their complex society, of their aspirations and their historical tradition, of the natural setting, and of the complicated functions and movements of the city world.’
‘by appearing as a remarkable and well-knit place, the city could provide a ground for the clustering and organisation of these meanings and associations. Such a sense of place in itself enhances every human activity that occurs there, and encourages the deposit of a memory trace.’
The use of method
Interview
Questions: p141-142
1. What first comes to mind, symbolises Boston? Broadly describe in a physical sense
2. 2. Quick map of central Boston (as if for a stranger, covering main features. Rugh sketch)
3. a) complete and explicit directions for route to work. Picture yourself making trip and describe sequence inc pathmarkers important for you. (pictures, names not important) and b) do you have emotional feelings about part of your trip? How long? Are there areas where you are uncertain of location?
4. What elements are most distinctive?
5. a) Would you describe X to me? If blindfolded, taken there, what clues you need to know where you are. b) are any emotional feelings with regard to X? c) can you show me on a map where X is and boundaries
6. show me on your map north
7. free discussion. A) what do you think we are trying ot find out, b) what importance is orientation and recognition of city elements? C) any pleasure from knowing where you are going d) is boston easy to navigate? E) what other cities do you know with good orientation. Why?
p. 155
Mass interview of large sample
a) draw quick sketch map of area, showing interesting and important features and giving stranger knowledge
b) make similar sketch of the route and events along one or two imaginary trips
c) written list of parts of the city felt to be most distinctive
d) brief written answers to a few questions. Where is X located?
p. 157 Also make sure not just a derivation of local culture. Interesting to look at whether images are art of cultural training.

Agglomeration Economies and the Future of Cities William C. Strange
William C. Strange, "Agglomeration and the Future of Cities," Policy Analysis and Economic Policy Conference, 2003. http://www.rotman.utoronto.ca/~wstrange/WS_Future_of_Cities_Wrkg_5-22-03.pdf
p.3
It is important to recognize that concentration is costly. Putting more business activity in
a small area raises the cost of doing business there in many ways: commutes are longer
and space is more costly to name just two. Thus, industry clustering must benefit
businesses in some way that compensates them for the costs of concentrating.
p.4
Cities are costly, as noted above. And there have been technological changes – relatively
cheap air travel and telephone communication, the invention of the fax machine, and
most notoriously the Internet – that have possibly made it less costly to locate away from
concentrations. Thus, there has been speculation that cities will decline in importance.
This is the biggest question of all.
P5
One answer to this question is that agglomeration exists because firms enjoy internal
economies of scale. Scale economies imply that the firm needs many workers; workers
concentrate to economize on commuting; thus, there is an agglomeration. This answer is
not completely satisfying, though, since it motivates only the existence of factory towns
and not the diverse cities that we actually observe.
A more satisfying answer is to say that there are "agglomeration economies", external
economies of scale that make firms more productive in large cities.
p.13
Our results suggest strongly
that firms must be quite close in order to benefit from each other's presence. And this is
true even in the software industry, where presumably everyone has access to email, and
so distance should not matter at all.
I would like to point out that our estimates also establish that diverse locations (low
values of "herf") are more attractive to new firms than are specialized ones. This is
consistent with the increasingly popular view that the benefits of clustering have limits.
It appears that small firms and nonsubsidiary firms have a greater positive
effect on their neighbors than do large firms and subsidiaries.
One interpretation of these results is that an entrepreneurial business environment is more
productive than a hierarchical environment. This certainly appears to be the case in the
Silicon Valley. In the mid-1980s, both the Route 128 corridor in Boston and the Silicon
Valley appeared to be comparable as centers of high-technology. In the intervening
years, the Silicon Valley has prospered, while Route 128 has not. Why? There are many
explanations. Saxenian (1994) has proposed that the difference in business culture is
key. Route 128 is hierarchical, dominated by large corporations. The Silicon Valley is
entrepreneurial, continually refreshed by startups.

The Economics of Housing
*see photocopy for detailed notes)
Housing as a stock and a flow. Distinction between asset and the accommodation services that can be derived from it.
Housing affordability best achieved by encouraging additional supply eg removing controls
Rent controls can actually lead to price increases as it increases demand but supply doesn’t move so some pay more (those who can afford).
Cost of subsidizing homeownership exceeds benefits
Ch 4
The Economics of Urban Structure
Pkanners affect real estate markets in two ways: first via zoning bylaws and other land use regulations that define the limits placed on landowners. Second, more indirect, planners intervene and shape the overall urban context in various ways
Bid rent curve
Different types of land use value distance to CBD differently, which results in successive rings of land use, with commercial in inner ring, and industrial and residential rings further out
Substitution principle: more expensive land used more intensively
From Wikipedia
The bid rent theory is a geographical economic theory that refers to how the price and demand for real estate changes as the distance from the Central Business District (CBD) increases. It states that different land users will compete with one another for land close to the city centre. This is based upon the idea that retail establishments wish to maximise their profitability, so they are much more willing to pay more money for land close to the CBD and less for land further away from this area. This theory is based upon the reasoning that the more accessible an area (i.e., the greater the concentration of customers), the more profitable.
Land users all compete for the most accessible land within the CBD. The amount they are willing to pay is called "bid rent". The result is a pattern of concentric rings of land use, creating the Concentric zone model.
It could be assumed that, according to this theory, the poorest houses and buildings will be on the very outskirts of the city, as that is the only place that they can afford to occupy. However, in modern times this is rarely the case, as many people prefer to trade off the accessibility of being close to the CBD, and move to the edges of the settlement, where it is possible to buy more land for the same amount of money (as Bid Rent states). Likewise, lower income housing trades off greater living space for greater accessibility to employment. For this reason low income housing in many North American cities, for example, is often found in the inner city, and high income housing is at the edges of the settlement.

The Economics of Land Use Zoning
p. 25 ‘perhaps no function is more central to what planners do than is land use zoning. Zoning maps apportion the city into district zones each of which has its own set of permitted uses: single-family residential, multifamily residential, commercial, retail, light industrial, heavy industrial, and/or other uses.’
Rationale@ keep incompatible land uses apart eg chemicals from school. Or more controversial exclude affordable housing from well-to-do neighbourhoods. This chapter considers economic efficiency.
“to the economist land use zoning is seen as an exercise in resource allocation, even if it may not normally be viewed in those terms by planners themselves.”
@how to allocate scarce resources in an efficient manner. If the quantity of land is fixed, as in most urban settings, then one if forced to make trade-offs. Zoning maps represent the planners‘ ‘solution’ to the resources allocation problem.
p.26
“An efficient solution is defined as one that yields the greatest possible output (such as social benefit) for a given amount of input (such as land)”
If market doesn’t generate optimal solution, can intervene. Zoning = “quantity-oriented mode of intervention, where zoning assigns each land use category a set quota of land… An alternative mode of intervention is price-based intervention, an option planners would do well to consider to attain planning ends more efficiently.”
p.29 ‘because the quantities of land devoted to either land use cannot be adjusted, any market adjustment must come in terms of prices (fig 2.1 a) market cleared price for resid and no resid is different *or and pn) ‘zoning has a direct impact on the price of the land.’
p.30
‘the market allocation tends to equalize the price of comparable parcels of land across all uses while the zoning allocation will tend to introduce price differentials between comparable parcels of land that are subject to different uses
p.33 ‘the market value of land understates the aggregate value because to fails to account for the rising marginal valuation of land as quantities become more scarce’
p. 35 ‘the aggregate value for all land under the market allocation M exceeds aggregate value for zoning allocation Z by the amount depicted….. We term this the triangle of inefficiency’ (aggregate loss in value
‘market allocation is always the one that generates the maximum possible aggregate value of land as measured by the market demand curves. This is a powerful result and one of the reasons that economists tend to be so enthusiastic about markets. Markets ‘automatically’ uncover the land use allocation that maximises the aggregate value of land.’
p.37
‘the term market failure applies to any situation where the market outcome does not produce the maximum social benefit.’
Market demand 2registers willingness to pay2
2it is not rare to encounter situation where the benefits or cost of the use of a good extent beyond the owner of the good in question. This is particularly so in the case of land use’ eg when the public gets upset about undesirable elements “noxious fumes, quality-of-life issues, or other environmental impacts that are not encapsulated in the market price of the parcel in question.’ termed externalities
p. 38 shows that when externalities’ taken into account a zoning solution can provide optimal benefits.
p. 39 ’the market develops the ’highest and best use’ of properties from the owners’ perspectives, but this may not coincide with the land use allocation that maximises social benefit.’
However market failure does not preclude possibility of regulatory failure. There are also positive externalities )often claim in favour of home ownership and stability2
p. 41 planners have been slow to use price to affect zoning.
p. 44 knowing what correct zoning or the ’benefit maximising allocation’ requires knowing the marginal benefit curve and few planners would claim to know that. Difficult to calculate.
But ‘the information requirement for price-based intervention is less onerous. Here the planner needs only to know the extent of the cost (or benefit) associated with the externality so that the correct tax (or subsidy) can be calculated’ for price based intervention… the market is left to uncover the new price allocation (after tax or subsidy). As market conditions change, the market continues to adjust itself, while zoning intervention requires recalculation of the optimum allocation each time there is a fundamental change in market conditions.”
p. 45
“seeking a rezoning on a specific parcel is akin to seeking special exemption from a tax’
‘public officials hold discretionary powers over legislation that impact specific individuals in favourable or unfavourable ways’ and ‘this situation may open the way to influence peddling’
Advantage of zoning is no money changes hands (corruption)

p.58. The tree is “a name for a pattern of thought, The semi-lattice or the name for another more complex mode of thought.”
“It Is more and more widely recognised today that there is some essential ingredient missing from artificial cities.”
“I believe that a natural city has the organisation of a semi-lattice; but that when we organise a city artificially, we organise it as a tree.”
p.59 example of newstack by a drug store next to a traffic light. Folks stop at lights, buy newspaper. This makes a unit.
p.60 “It is this lack of structural complexity, characteristic of trees, which is crippling our conceptions of the city.”
Says gReater London plan 1943 by Abercroimbie and Foreshaw concerned by a large number of communities, increased segregation. Tree.
p. 62 “In a traditional society if you ask a man to name his best froends and then ask each of those in turn to name their best friends then they will name each other so that they form a group. A village is made of a number of separate closed groups of this kind. But today’s social structure is utterly different. If we ask a man to name his friends and then ask them in turn to name their friends they will all name different people, very unlikely unknown to the first person; these people would then name others and so on outwards. There are virtually no closed groups in modern society.”
May (second part of article)
p. 59 Le Corbusiee, Luis Kahn and others separate moving vehicles from pedestrians. “It’s not always a good idea. The urban taxi can function only because pedestrians and vehicles are not separated.”
p.60 remember four objects: orange, watermelon football, tennis ball. You do it in mind by grouping them but cannot imagine in mind all the possible groupings at same time. “In a single mental act you can only visualise a tree.
“The tree is accessible mentally and easy to deal with. The semi lattice is hard to keep before the mind’s eye and therefore hard to deal with.”
Says tendency of humans “when faced by a complex organisation, to reorganise it manetally in terms of non-overlapping units. The complexity of the semi-lattice is replaced by the simpler and more easily grasped tree form.”
p.61 “When we think in terms of trees we are trading the humanity and richness of the living city for a conceptual simplicity which benefits only designers, planners, administrators and developers.
“In a society dissociation is anarchy. In a person, dissociatioon is the mark of schizophrenia and impending suicide.”
Separate old people from young eg Sun City. Result of “tree like thought.”

2. Cities no longer regional centre places but ‘critical base points of globalization’
3. postindustrial city
New Economy
Knowledge based, enhancements of human capital, technology, cultural economy
Means spatial, structural, social and land use consequences
(Graham and Marvinàs 2001 ‘splintering urbanism’)
New Economy and cultural economy concentrated in inner city
p.7 New Economy is ‘relatively new, creative and technology-based industries such as communications, consultants, computer software design, computer graphics and imaging, computer networking and Internet Services.’ Also advertising, architects, fashion design, graphic artists, designers, industrial design, film, music and print media.
Or ‘high value cultural products’
Reoganisation of inner city space with new primary production sites, place based production networks and sets of linked industries
p.8 new industry formation seen as revival of inner city industrial sites
p.9 ‘new industry formation in the inner city can play a part in the reconfiguration of the metropolitan core’s space-economy, redressing to some extent the spatial imbalance of the postindustrial core which heavily favoured the corporate complex of the CBD, and partially offsetting job losses in central city industries and occupations.’
Also local area regeneration – start ups, infrastructure, jobs, supply and contracting
p. 10 Flora (2002) creation fo creative class
p.39
Reconstruction of economic space
Forces reshaping the production economy of metropolitan core in postwar era, inc corporate office complex in CBD (densest employment district), collapse Fordist production and labor in inner city
p.73 London
City spatially constrained but can grow with policies allowing higher buildings
Westminister and Camden creative industries with concentrations boutique hedge funds Mayfair, film and video production or graphic design and advertising soho plus New Economy. Canary Wharf. Industries next to Heathrow. Bankside cultural enclave.
p.74 ‘the historic bipolar spatiality of london’s economyt, concentrated in the cities of London and westminister, has thus been supplanted since the 1980s by an increasingly polynucleated structure’ (although City still densest wealth creator centre in Europe)
p.100
‘London’s inner city can be characterized by a uniquely rich and diverse structure of production regimes (pre fordist, fordist and post fordist), indusyries and labour, exhibiting important developmental continuities as well as disjuncture.’ But in last 40 years ‘deep swings defining its development trajectory’
New Economy of inner city is ‘less stable, subject to recurrent abbreviated restructuring processes, punctuated by recessions and downturns, and increasingly vulnerable to the vaguaries of London’s propert market’
‘the London property ,arket is crucial to the fortunes of industry and employment
p.138
boroughs leaders rather than followers. NGOs also active, relationships with local actors. Mayor and gla
p.141 emergence of new industries could be revival of identitits of former London boroughs (Hoxton, Shoreditch, Bermondsey Clerkenwell) ‘onve vital and highly distinctive industrial and social plavces withint the burgeoning London metropolis of the nineteenth and early twentieth centures and now recalled to life as centes of experimentation, innovation, and cultural class,’
Singapore, San Francaisco, Vancouver,
p.278-9
‘Recombinant economy of the inner city’ means complex if industries, firms and institutions situated within evolving twenty first century metropolitan core. Multilayered construction of inner city’s economy as recombinant, shaped by comlex synergies, sytheses and interdependencies.

Sustainable Urban Design An Environmental Approach
Sustainable Urban Design
An Environmental Approach
Adam Ritchie & Randall Thomas
2nd Edition Routledge 2008
Book designed to inspire rather than prescribe
p.3 ‘Ideas of planning, space and lace are a bacdrop to many of the points made, but out built environment suffers enough at present from people who were too sure of their solutions and those who thought in ’silo’-based terms and over-planned, and this over-constrained development.’
‘density and the means of moving around the city are related. Landscape affects buildings.’
Sustainability = social, economic and environmental
p.4 ‘cities must have a rich set of interconnections or they will not be sustainable’ eg walking/ cycling means needs diversity ‘accidentals’ in street patterns and buildings. ‘we need to develop a rhythm in the city that will include places we can enjoy; this rhythm will be about moving and stopping. This will help us return to cities designed for people, rather than for cars.’
Planners miss ‘accidentals’ eg views as ‘obsessed by regular patterns from an impossible aerial view.”
p.5 Irregular streets of Malmo’s new W Harbour. Klas Tham architect described as ‘distorted by wind like a fishnet hanging out to dry,’
p.7 cities: think if systems like ecologists do when looking at energy flows in nature
p. 8 wind good for ventillation, energy
Chapter 2
p. 12 ‘when the means of movements changes, so too do patterns of human activity with direct consequences for the planning and design principles that guide the development and renewal of urban areas.’
A we ask to reduce reliance on cars and encourage walking and cycling, change urban structure from street blocks to buildings
‘People’s requirements and technology change faster than places’
p.13 towns depend on hinterland for food. Hinterland depends on towns for markets for goods
So sustainable planning requires holistic and integrated approach t urban region that recognises interdependence of town and country
p. 14 Walkable community characteristics
- shops and services focus on main street in heart of n’hood at convergence of movement routes and around key facilities such as railway station
- schools, health centre, open spaces distributed around neighbourhood
- mixed affordable housing
- housing density highest around edge of centre along transport routes and near amenities
- movement routes shared by cars, buses, cyclists and pedestrians
- lans often marginal or in short term use at ‘shatter zone’ or interface between established ail and commercial centre and residential hinterland reflecting uncertainty or speculation
p. 18
Lessons learned include
- Socially mixed inclusive communities
- service and facilities porvision
- community discussion
- public transport
- long term management and maintenance is important as initial design
Chapter 3: Transportation
http://www.london.gov.uk/mayor/strategies/transport/trans_strat.jsp (doesn’t work anymore. Accessed 2008)
Says in 200 average speed of cars slower than horse drawn carriages around 10 mph or 16 kmph
http://www.dft.gov.uk/pgr/statistics/datatablespublications/personal/mainresults/nts2002.nationaltravelsurvey2002revi5243
40 percent of UK commute to work by car (not there anymore_
Cycling can be quicker
p. 27
Car clubs, bike racks on buses, fuel efficient cars, busways on railway tracks
High quality design of buses trams, trains as well as their stops and interchanges is widespread in many continental European countries counteracting the impression that public transport is only for thosew who cannot afford a car
p. 28 congestion charge
Www.tfl.gov.uk/assets/downloads/thirdannualreportfinal.pdf
8 pounds charge means transport delays down 30 percent, 18 percent drop in vehicle traffic 37 percent increase in people entering congestion zone by bus. In 04 to 05 raised 97 million pounds for investing in public transport
Christiana Bike (Copenhagen) can carry luggage or small children
p.30 effective actions
- reducing traffic speeds, priority pedestrains and cyclists
- attractive public realm
- better pedestrian cycle links
- balance pedestrians/cyclists/motorists reprioritised away from the car in urban centres
- improving public transport
-new developments situated close to public transport routes
Chapter 4: Landscape and Nature in the city
Drainage, planted roofs
p. 32 vegetation uses eg noise, co2 extraction, retain rainwater, temperate, windbreak
Also human behavious. Less prone to violent behavious in tree lined streets *cites Times article ’Can Trees Cut Pain@- 2001.
p.37 colour therapy green neutral colour in middle of spectrum. Easiest to see when exhausted
Chapter 5 Building Design
Europeans spent about 90 percent of time in buildings.
p/ 42
’buildings should be designed from the inside out and the outside in simultaneously - designers need to imagine what the conditions will be for the occupants and passers-by. Moving through the building should be an interesting, delightful and rewarding experience’ cites De Montfort Queens Buidling
Key considerations (p.43 to44)
Reduce demand
- for energy by max solar gain, seal building, use less water, Try to avoid air conditioning, integrate structure and services, choose materials carefully
p.45 ‘successful spaces are those with good daylight.’
p.48 model shows three typical urban forms with same density of around 100 dwellings per hectare
1. Courtyard housing can create strong sense of place and community. Some self shading
2. Slabs. May feel soulless if not handled well. Use sun well
3. tow block. Distinctive character, solar potential depends on context
Designers increasingly focussing on roofs to serve as solar collectors, rainwater harvesters, green space for biodiversity
‘it is important that buildings should be capable of being altered within their lifetimes to allow for new technologies and social changes.’
p.52 Jean Nouvel’s Catrier Foundation set a glass building back behind a glass screen, thus protected from noise and pollution of Blvd Raspail
p.53 ‘tower blocks only work both socially and environmentally if the space between them is successful; an dif they are well managed.’
p.55
Guidelines
-Do things that cost nothing first: get orientation, form and massing correct
- consider factoirs inc street pattens, energy consumption, energy production
- insulation
-Daylight
-‘Buildings and cities are for people’
-low energy ventilation
- can be altered over time
Chapter 6
Energy and Information
p.70 ‘Generally one is trying to arrive at a reasonable economic balance of providing environmentally friendly energy to meet low-energy demand.’ energy reduction methods start to become more expensive due to diminishing returns so at a cross over point one switches to supplying energy in envion friendly ways
Chapter 7
Materials
p. 74 Cities cover 2 percent of world’s surface but use 75 [ercenbt of material resources (cites lawtn j 2007 royal commission on environmental pollution, 26th report the urban environment London tso p2
Selection criteria for materials
Suitability, economic cost, impact on local dna global environment, health hazards
p.76 Concrete used for structural properties when combined with steel, but also thermal mass and acoustic insulation. Since 1990 industry has improved energy efficiency by 25 percent. New technologies eg self cleaning
Chapter 8
Water
Surrey is drier than Syria (national audit office 2005 report environment agency; efficiency in water resource management
p.85 reduce demand, re-use rainwater if possible, bath water recycling (eg for WC)
Chapter 9
Waste and resource
Case Studies
Ch 11 pp96-105
Coopers Road Estate: Regeneration
Was a failing 1960s estate. Southwark Housing demolished and redeveloped with Peabody Trust. Local consultation also with neighbouring estates by ECD architects. Tenants influenced choice of heating system and layout of homes. Two bedroom homes given separate bathrooms and Wcs.
Design principles
1. Designed around four courtyards of around 40 homes each in mix one, two and three bed (even four)
2. Integrate architecture and landscape for legible and easily maintained public and private spaces
3. Develop community ownership. Rear gardens facxe onto larger communal garden
Gardening clubs to help skills
Sustainability strategy focussed on energy and co2, wtare conservation, materials sourcing, waster manegment transport, social well being
Ch12 pp105-115
Parkmount: Streetscape and Solar Design belfast
Street frontage
P 110 ‘landscape areas and open sapce whose ownership is common or ambiguous are often poorly maintained or vandalised, which in trun has implications for crime prevention and personal security.’
In Belfast gated communities common but didn’t want here. But residents want good visibility and surveillance. So clear but secure entrances. Repeated blocks of dofferent heights bend to take advantage of sun. roof helps unify scheme.

Perrons Globalization and Social Change
Perrons (2004) 2004. Globalization and Social Change: People and Places in a Divided World. Routledge Chapters 3 and 5
To accompany Lecture 1. Uneven development among cities
Pretty much a recapitulation of the lecture. Notes taken. Jist is you need theory to figure out what is going wrong, but depends what theory. Perrons doesn't like the theory that market processes lead to convergence (see quote p.59). She claims it is uneven, leads to what she calls clustering. With globalisation, geography should not matter, "yet at every spatial scale, the global, the nation, the region, the city or locality, economic activity is clustered." She also looks at whether development is ethnocentric or value laden. .
On Ch. 5 she looks at the global division of labour, which she says is uneven. The West is becoming increasingly distant from the production that comes under its name. Nike, for example, concentrates on brand and marketing. The further it gets from production, the less control so the more exploitation. p. 136 UK highest proportion of population living in poverty in the EU, and highest nummber of children in poverty (after Italy). p. 142 Under Fordism when unions were strong and collective bargaining led to high wages and stable jobs, all were happy. Now, p. 160 "capitalist societies are characterised by eneven development."
