Spatial Layout as Critical Infrastructure

Stub…notes for an upcoming conference talk

Key issue to be addressed:

- Urban-Rural development

- Urban Regeneration

- Smart Cities.

When a network of streets is laid out, planners and designers build in an enormous amount of “embedded potential”:

  • the pattern of movement
  • land use potential
  • safety
  • land value
  • social interaction
  • public health
  • carbon emissions.

The design of the street network has a fundamental and measurable influence on each of the above.

Later changes – to land use pattern or to the local design of streets (eg road widening or narrowing, adding cycle lanes or public transport) – can enhance or even diminish these potentials, but such later changes always occur around a benchmark that is set by spatial configuration decisions.

Buildings come and go – are built and demolished – but the spatial network, once laid out, is harder to adjust.

Exceptional new connections – such as bridges – can be built to connect disconnected networks but grids are resilient to change. Therefore, putting the wrong grid into an urban development can be a pathological move, setting the socio-economic potential of places for generations to come.

How do we know this?

The evidence-base: post-war housing estates; UK New Towns. Places that go wrong within a generation, if that – sometimes within a few years. Car-dominant transport planning. Land use zoning.

Risk of failed UK models.

In finding a balance between the tension of urban and rural development, Chinese towns and cities should learn from China first:

- mixed use planning: marginal separation by linear integration.

- mixed mode planning: roads, streets, lanes, canals: Jiading.

- mixed character planning.

What are the Spatial Layout requirements?

The historic Chinese grid: rectilinear hierarchy.

Pervasive centrality.

A smart street-grid.

Smart Cities World Expo – speaking notes

Spatial layout influences
Human behaviour:

1. Movement

2. Awareness

3. Interaction

4. Transaction.

Spatial layout benefits
1. Economy
- productivity
- innovation
- building & campus performance

2. Health
- active travel
- access to healthcare
- building & campus performance

3. Social cohesion
- the spatial network creates the social network

4. Safety
- property theft
- personal attack

5. Environmental performance

6. Educational achievement
- access to education
- building & campus performance

7. Cultural identity

Spatial layout
Is defined by:

1. Location

2. Linkage

3. Layout

4. Land use

5. Landscape

These are each measurable commodities/parameters. They are the building blocks of human behaviour and, ultimately, cultural identity.

Our proposal
To put spatial analysis at the heart of city systems integration. As the common ground. As the core code of the urban operating system.

A smart city
Is one which:

1. recognises the fundamental role of Spatial Layout Design

2. embraces a technology-driven approach to Spatial Layout Analysis

3. embeds Spatial Layout Analysis in the Planning and Management of the city

4. evaluates investment decisions using Spatial Layout Analysis.

A short film about Space Syntax

Tim Stonor, Managing Director, Space Syntax
“The population of the world is increasing and, as it increases, more and more of us are living in cities. As cities have grown in the 20th century they have often grown to disconnect people.

Space Syntax has discovered that many of these problems in cities – disconnection, lack of contact between people, lack of access to jobs – come down to the way in which the city is planned as a layout of space.”

Ronan Faherty, Commercial Director, Land Securities
“As a developer, the most important thing for us is understanding the consumer and anything that assesses the consumer and helps us understand them provides real value. When you’re putting down a new property into an existing space we want to understand where consumers are coming from and then how they should engage with the property: where we should put escalation and movement and flows.

Life by a thousand connections

Background
The everyday actions of architects and urban planners influence the everyday physical activity of people by creating the networks of streets and public spaces through which people move. Similarly, inside buildings, the layout of space influences the degree to which people move around.

The precise mechanisms through which spatial patterns influence behaviour patterns are increasingly well understood by the academic community. Physical connections are key: well-located pedestrian crossings, cycle lanes, bridges over rivers and canals, simple and direct routes through housing areas and town centres. Well-located shops and public buildings are key: within walking and cycling distance. Good quality paving matters, as does good lighting.

Nevertheless, this scientific knowledge is not yet part of everyday practice. Some of these findings run counter to accepted planning practice, not least transport planning practice.

Nor is the connection between planning/design on one hand and physical civility/health on the other embedded in practice. The world of architectural and urban planning practice is heavily silo-ed. Health outcomes are not a priority for architects and planners. Continue reading

Notes for AGI Conference talk: Measure, map, model, make

My slides

Great placemaking is a process combining art and science. There is a place for both and indeed a need for both. Two problems. First, urban planning is largely an analogue discipline. Too many diagrams and watercolours. Not enough science. And, when science is present, it is seen as an adjunct, not as a driver.

Space Syntax has harnessed a scientific technique and used it to drive a creative process. This scientific technique is geospatial. It is all about what goes where and how it is connected together. This should be of interest to this conference. Continue reading

AoU Landscape Urbanism notes & questions

These notes accompany a PowerPoint presentation Fragmented urbanism: the rise of Landscape Urbanism & the threat it poses to the continuously connected city

TS intro
This is a crucial moment for urbanism. In the UK, The Portas Review, highlighting the UK’s threatened high streets. Around the world, cities are growing faster than ever. But cities – as we knew them – are under threat.

First, from the car. Car-dependent urbanism is the principal form of urbanism on the planet. our cities have become so fragmented by road systems in the last century that it is now almost impossible not to be far dependent – not without a major demolition and reconnection programme.

Second, from designers, accepting of the car and intellectualising around this complicity.

The aim of this talk
I have been forming my own views about Landscape Urbanism and am looking to raise a discussion within the Academy of Urbanism and beyond. Do people agree with me? If so, how do we respond? If not, why not?

Summary of the Landscape Urbanism aesthetic
Parcels of grey wrapped by ribbons of green

Landscape Urbanism as anti-ecological
“If you have a culture that is fundamentally automobile-based, then an urban model that is anti-automobile is counterintuitive at best. There’s a strange precept these days that asserts that people will abandon their cars if we simply build cities that don’t accommodate them”.
Charles Waldheim

Notes

Interim uses eg temporary food production. How can this be coded?

Layouts need to be walkable and workable.

What will the future city look like?
The city of transaction

How to plan a socially, economically and environmentally sustainable city
The effects of the digital revolution on human behaviour patterns

Tim Stonor, Architect & Urban Planner, Managing Director, Space Syntax (UK)
_____________

Data is not the solution.
Turning data into knowledge is a beginning.
Turning knowledge into wisdom is the next step.
Turning wisdom into action is the key.

All of this requires theory.

Here is a theory of the city.
It begins with a description of the city as a geometrical configuration.
Of land uses and linkages.

Addressing the question that planners ask. That politician ask and demand of planners. That property developers make and lose money on.

What goes where and how is it connected together?

“What will the future city look like?”

View the presentation

Themes to be addressed
1. How to plan a socially, economically and environmentally sustainable city.

2. Effects of the digital revolution on human behaviour patterns.

Summary
In addressing the question, “What will the future city look like?” I am less concerned about the visual appearance of individual buildings and more concerned about how the city is planned as a layout of streets, spaces and land uses.

Why? Because the spatial layout of a town or city organises the movement and interaction of people. Movement and interaction lead to social and economic transaction. These are the building blocks of society, of culture and therefore of being human.

The end of ages for transport planning and the birth of an era of transaction planning

There is so much interest, from so many different interests, in the future of urban living. This suggests that, whatever else, people suspect that things will change. I’m sure this is right – technology, resource scarcity, population growth, energy shortage and climate change: all are factors that will provoke change. The question is, will these changing “inputs” affect the shape and form of the “output” ie the look and feel of the city?

Again, the short answer is “yes”. But not in a sci-fi, megalopolis, flying cars kind of way. Nor in a “let’s all abandon the city and live in rural bliss, connected to each other by the Internet”.

The reality, if done well, will look and feel strikingly familiar. We will in the main, by necessity, live at density and travel on foot and by bike, making lots of small journeys and a few larger ones. Likewise we will, by necessity eat local, reduce, recycle, reuse. Cities will be incredibly green because we will, by necessity need to harvest rainwater, prevent runoff, shade streets.

The effects on social and economic productivity will be enormous. The quality of human interaction will be enhanced.

Having been through an era of evermore globally connected urbanism, with the consequently divisive effects of major traffic arteries on local communities and the throttling or urban centres by that 60s badge of honour, the ring road, we will move to an age of continuously connected, convivial, landscaped urbanism.

For me, this can be summed up as a change from “transport planning” to “transaction planning”. This will necessitate an end of ages for the traffic engineer and the birth of an era of sophisticated, humane urbanism.

Ed Glaeser at the American Planning Association

Notes from Prof Ed Glaeser’s keynote at the 2011 American Planning Association Conference in Boston, 12th April 2011

A city’s “innovative density” is provided by its urban connections.

Historical urban growth and decline
Historically, cities grew by water.
As transport costs lowered (now 10% of a century ago) people and production did not need to be near water hubs – leading to suburbs and low density living.

Warmer cities grow faster.

Transportation
The car is a product of a city (Detroit) but not the kindest of progeny.

Average US car commute 24min
Average US pub transport commute 48min

The hallmark of declining cities is that they have an abundance of infrastructure. Governments need to invest in people not in infrastructure. This was the mistake of the Detroit people mover, passing over empty houses on empty streets.

Cities that come back eg NY through the influence of financial markets – a fact that is not discussed enough.

Wealthy people live in and work in cities because, in terms of making money, intimate knowledge is more important than having lots of space eg the Bloomberg bullpen, modelled on wall-less financial market settings.

By being around smart people we become smarter.

More skilled areas have grown more quickly.

Cities are places of promise and poverty. Urban poverty is not sign of failure but of success. Dharavi attracts people with a promise of a better life; better than the enforced sterility of the suburbs.

If, when a subway stop is built, poverty levels rise in the vicinity of that stop, is that a bad thing? No, it shows that subways attract people who can’t afford to drive – this fact should be celebrated.

Roads and driving
The answer is not to build new roads.
Turner showed that “If you build it they will drive”.
Congestion charging is the solution. There is no right to drive in the Constitution.

Conclusions – Policy changes needed
1. change the US obsession with home ownership, especially large houses. Typically, even lower income homes in the US are 2x those in the UK and Germany – by making urban housing expensive, the federal government is socially engineering poor people into suburbs

2. change the US federal obsession with building highways, especially in low density cities

3. reform the schools system that is forcing people to suburbs in search of good schools.

Thank you for coming and thank you for what you do. Planning matters because space matters.

Everyone in LA should have an equal opportunity of being eaten by a mountain lion

MIT Media Lab8th April 2011

In accepting the 2011 Kevin Lynch Award at MIT, Randy Hester gave a provocative speech about the enduring importance of urban design. Here is my tweetroll from the event.

Randolph T. Hester wins Kevin Lynch Award @MIT – giving powerful talk abt risks of virtual capital that doesn’t care for “place”. #urbanism

18:34
RH – everyone may not care about greenhouse gases but everyone cares about #nature – concern for nature is the gateway to ecologicalism.

18:38
RH – there is a paradox btwn ecology & democracy and a need to harness the paradox, leading to new, recombinant urban/ecological aesthetics.
