Walking and car free living
  • A car free living environment should allow good
    accessibility on foot, for example to local shops
    or public transport services
  • More generally, modal shift from the car to
    public transport and walking needs a walking
    environment that people feel comfortable in
  • various built environment features, such as
    street width, block length, sidewalk width, the
    presence of sidewalk buffers, etc, may create an
    environment that is judged to be 'comfortable.
    (Alfonzoa, 2008)

Walking and city life
  • A lot of work has connected walking and the
    quality of urban life. Some of this comes from
    the psychogeography (Evans, 2008) and
    flâneurial (stroller) traditions (Binns, 2008
    de Certeau, 1984) which focus on the experience
    of being within the city
  • The experience of city life has also influenced
    Jan Gehl (1999) and others, although this tends
    to be a more European tradition
  • The New Urbanist tradition (Baran, 2008
    Erenhalt, 2008 Katz, 1994) values close walking
    distances highly

5
Walking and space
  • Walking is a movement through space, the points
    we pass through connect physical cartesian
    space to perceptual space
  • Space Syntax deals with movement through space
    and can predict locations where more pedestrians
    will be found, at better connected points on the
    street network (Hillier, 2004 2008)

Walking and sense
  • Walking differs from other modes of transport by
    direct interaction between the pedestrian and
    their environment (Gehl, 1999)
  • Researchers have used the ideas of sensewalking,
    capturing what people feel and sense during a
    walk (Adams, 2008 Clark, 2008)
  • Nold (2008) used GPS units to record walking
    routes, and measured galvanic skin response along
    the route to indicate arousal (good and bad)

Connecting walking to urban form
  • There have been a large number of studies looking
    at the connections between urban form and walking
    (Cervero, 2002)
  • Much US research focuses on New Urbanist
    neighbourhoods, a reaction to sprawling car based
    suburbs involving Neo Traditional Development
    (Ewing Cervero, 2002)
  • Modelling the urban environment has frequently
    resulted in problems of multicollinearity as
    aspects of urban form tend to vary together
  • Other studies have used Pedestrian Environment
    Factors (Greenwald Boarnet, 2002) or Level of
    Service measures (Muraleetharan Hagiwara, 2007
    Tight et al., 2004), which involve some
    subjective judgement in the allocation of
    categories
  • Many studies have focused on number of walking
    trips
  • This study aims to use less subjective measures
    of urban form and more subjective measures of
    human interaction

8
Proposed study
  • Aims
  • To produce a language for describing urban form
  • To explore the connections between the physical
    nature of urban form and how people perceive it
  • To assess the current orthodoxy relating to
    walkable environments

9
Research Questions
  • How does the nature of the urban environment
    affect the perceptions of pedestrians?
  • What do ordinary people consider important about
    walkable environments?
  • Is the New Urbanist philosophy appropriate for
    the UK (it has influenced guidance such as The
    Manual for Streets (DfT et al., 2007)
  • Does the accepted wisdom on walkability
    resonate with how people perceive their
    environment?

10
Method
  • Urban form analysis
  • Identification of Urban Structural Units (Osmond,
    2006)
  • Grouping of units into a taxonomy reflecting key
    areas of similiarity
  • Space Syntax (determining levels of integration
    of the street network and how this affects
    walking (Baran, 2008 Hillier, 2004)
  • Determination of walking routes (including areas
    of high and low integration)

11
  • Walking interviews
  • Group based commented circuits (cf. Tahrani,
    2008 Tight et al., 2004) featuring first
    experts (eg planners) then ordinary people
  • Group scenario should foster debate
  • Tagging of comments to location to compare with
    physical properties (cf. Nold, 2008)

What should this achieve?
  • Identify the connections between perceived
    space and real or cartesian space (cf. de
    Certeau, 1984)
  • Overlay subjective properties (thoughts
    feelings) onto objective properties of urban form
    (Urban Structural Units, Syntactical Integration
    etc.)
  • Improve understanding of the connections between
    urban form and perception
