This post contains an essay submitted as part of student course work for the Planning 100 "Introduction to Planning" course taught by me this year at Planning School, University of Auckland. The topic for the essay is: Comment on the influence of different forms of transport in shaping urban form and the way people live in an urban environment. Investigate and explain the key transport issues facing those responsible for planning Auckland's future. The essay is about Auckland planning and is by Luke Carey, who has kindly given permission for it to be published here.
Transport has defined urban life for as long as cities have existed, and it is far from being a
‘new’ domain of planning, yet it is still considered the biggest issue facing 93% of Aucklanders
(Transit NZ, 2005), and the general public perception is that it is somehow ‘wrong’ and needs to
be ‘fixed’. Ancient Rome by AD 100 with a reported population of one million had developed
“immense problems of traffic congestion” (Hall, 2002). So why is it that after millennia of the
issue existing in our cities, we somehow still struggle to get it right? How have different forms
of transport influenced Auckland’s development over time? And why has this resulted almost
exclusively in a pattern of urban sprawl and segregated zones of activity? The ability for the
transport sector to rapidly diversity in order to accommodate outside factors causing change in
society such as peak oil and climate change is questionable. It is becoming clear that the
complicated urban fabric of the city is not the problem, but the solution, and that the key to
transport success is achieving integration and avoiding having modes compete with each other.
Early 19th Century Auckland was dominated by coastal shipping and trade. Governor William
Hobson selected the site in the then Commercial bay (now Fort Street) for the new settlement
based on it’s easy access to both the Waitemata and Manukau Harbours, and a second port
soon developed at Onehunga. Early development was sited around access to the wharves that
scows transporting goods up and down the coast would trade from. Railways and roads were
developed from 1870 onwards under Sir Julius Vogel’s infamous Public Works Scheme but it
was not until the 1930’s and an extensive programme of tar sealing roads that suburban
dwelling became widely possible. We never looked back. The suburbs of “cosmopolitan
Auckland” reportedly “exploded” in the post war era. “It is the edges of the city where the
residential areas are thrusting out to all points of the compass that the really spectacular
changes are taking place”. “The shopping areas are new, up to date, convenient, the road gangs
moving further and further into the country, Auckland’s fortunate in having room to grow, and
with the roads comes the houses, a town the size of Whangarei goes up in Auckland every 12
months” all this new development was terribly exciting (TVNZ 7 Hindsight, 2011). By 1950
Auckland was contemplating an extensive motorway network to cope with this rampant
growth, which had the city bursting at it’s seams (Bush, 1998). But De Leuw Cather, the
overseas consultants contracted to design the motorway system issued a written letter to the
Auckland Regional Authority in 1965 emphasizing the importance of balancing investment in
the highway and motorway program with investment in a “transit” system that included
significant rail improvements to avoid “unfortunate” consequences on “land use development”,
or built urban form (Cayford, 2012). Nearly fifty years later, and most of the motorways have
been built, but the ‘transit’ or public transport system most certainly hasn’t been. Why?
A common understanding we have is that the railroad tends to concentrate growth, and the
automobile disperse it. The common view of urban sprawl (in abstract) is one of hatred for
most people. We “deplore the loss of open space and farmland, long drives, congestion, and
the boring uniformity of suburban development” (Bruegmann, 2005), not to mention air
pollution, climate change, and the resulting segregated zones of activity. But when put in the
context of how it might affect our ability to live the quarter-acre New Zealand dream it seems
that suburban development is just “a natural market response to the desires of millions of
individuals”. That is, as Bruegmann argues, we have it because we wanted to live at lower
densities, and this was the primary cause for the growth in the transport industry. The
enormous increase in mobility that came with it made sprawl possible, not caused it, and not
the automobile specifically. So does the locational preference for life in the suburbs still ring
true in New Zealand today? A 2009 ShapeNZ survey of 3244 kiwi’s had 80% of respondents
state they would prefer to live in a stand-alone house than an apartment. And if there were no
constraints on where respondents chose to live, 73% would choose to live in either the suburbs,
or an even more low-density country lifestyle block or farm (N Preval, 2010 ).
Glaeser (2011), in his novel Triumph of the city contradictory to Bruegmann takes a more
common stance by arguing that “modern sprawl is the child of the motorcar” and the urban
form of our cities in general is directly influenced by which mode of transport is used. “The first
12-person omnibus appeared on New York’s Broadway in 1827, it was subsidized by the state
and given right-of-way on the city’s streets, enabling the prosperous to commute into New York
from less dense quarters uptown” (Glaeser, 2011), and so the suburban pattern started. He
says that transport developments have been by far the most important, but not the only factor
that made suburbanization possible, that it also involved cheap mass-produced housing and
government incentives to make it widely available to the middle class. In New Zealand, this
need was fulfilled by the government’s vast state housing schemes of the post-war era that
gave people little diversity in housing choice, and government funding for vigorous motorway
building schemes such as the Auckland Harbour Bridge and it’s associated northern motorway
(Bush, 1998).
With the benefit of hindsight, it has become clear that tomorrow’s solutions to our transport
woes should place much more emphasis and importance on the co-benefits of alternative
modes of transport, such as active modes and public transport (Howden-Chapman, 2010). As
Jamie Lerner puts it, “The car is like your mother-in-law, you have to have a good relationship
with her, but she cannot command your life.” “So when the only person you have in your life is
your mother-in-law, you have a problem” (Lerner, 2008). A more balanced approach to
transport will result in more resilient communities. The transport system needs to “adapt to
new challenges that span the environmental, social and economic range” of life in cities, such
as peak oil and climate change, and these challenges all point very clearly towards increased
use of alternative modes of transport (Howden-Chapman, 2010). New Zealand rail, for example
is on average 47 times more efficient at moving goods and people than roads. (Hindsight, 2012)
There is also a direct relationship between vehicle kilometers travelled (VKT) and urban density.
As average density increases, vehicle kilometers travelled decrease, with a doubling in urban
population density resulting in a 25-30% reduction in vehicle miles travelled (Ewing, 2010).
Higher-density living, particularly along transport corridors, also supports higher per-capita use
of alternative means of transport (Ewing, 2010). Therefore, the relationship between built
urban form and transport is mutual, and changing the built urban form of an area can also
address issues in transport. For example, designing and zoning for mixed use activity like what
we have in Auckland’s CBD and Takapuna instead of segregating land-use activities like in
Albany or Pakuranga should, in concept, also reduce VKT.
But investment precedes growth, particularly in public transport (Auckland Transport, 2011).
Curitiba’s infamous bus rapid transit system (BRT), now with over 220,000 passengers daily,
was conceptualized in the 70’s and 80’s and started on just 20,000 passengers a day. (Lerner,
2008) It has now revolutionized Curitiba’s transport system and urban form, with high density
development having been concentrated along the BRT corridors. But Lerner emphasizes that
the key is having an urban form and transport system that avoids having modes directly
compete against each other and achieving integration between different modes; the better
integrated the system is, the more potential it has to be successful.
In Auckland, we currently have a discrepancy between the priorities of central and local
government, with a more balanced approach to growth and development of urban form being
advocated by local government in response to a resurgence in the popularity of alternative
modes of transport (Auckland Regional Council, 2010) and desire for more compact urban
development. Whereas central government continues to invest in highways without funding
alternative forms of transport, such as rail improvements, and advocate the relaxing of the
metropolitan urban limit (MUL) instead of increasing density within the existing urban area
(Mees, 2006). It’s my opinion that this discrepancy will, for the time being, be the most
significant difficulty we face in planning for Auckland’s future. Investment in “both public
transport services and infrastructure has not kept pace with the growth in travel demand”
(Auckland Regional Council, 2010). This restricts people’s choice of transport modes and the
viability and amenity of alternative means of transport. The most efficient and integrated,
forward-thinking outcomes seem to occur when a specific public transport project has central
government support, such as rail network electrification and the northern bus way.
If we are to see a more balanced outcome to transport investment in Auckland, we also need to
see backward-thinking rules and regulations such as minimum parking requirements removed
from our legislation. These have an economic cost and in places where alternative means of
transport are available undermine efforts towards balanced investment because they directly
compete against other modes (Auckland regional Council, 2009). The transport strategy claims
that if we increase roading capacity by just 9%, and public transport services by 130%, then we
can expect congestion in 2040 to remain roughly at current levels (Auckland Regional Council,
2010). Interestingly, the expected increase in public transport usage (270%) at this level of
investment is also expected to have roll-on effects of increasing walking and cycling trips by
128%, so the solutions are there, it is simply a systemic change in the way we assess projects
and manage transport funding that is needed to make these solutions possible, especially at a
central government level.
In conclusion, transport and urban form have a mutual relationship, they both affect each
other. The railroad tends to agglomerate development while the private car disperses it. The
dominant pattern of transport has been growth in use of the private motorcar and investment
in roading infrastructure that has seen an unprecedented growth of the suburbs. While this has
historically met the ‘quarter acre kiwi dream’ it has had other consequences on the quality of
life in our cities that we deplore and could be called a tragedy of the commons. The result is an
unbalanced transport system in Auckland that is not currently serving the needs of it’s people,
and this pattern will continue to increase unless significant systemic changes in transport
funding towards alternative modes are made. It is quite possibly the biggest issue facing the
growth and development of our city and is not an issue that is solved overnight, but investment
precedes growth, and the first step is to introduce a more balanced model of funding and
transport policy that values and encourages growth in alternative means of transport.
