- Jul 23 3:15 PMRecently Auckland, New Zealand has just completed a busway complete with
stations on the North Shore of Auckland Harbour. This is a distinct
dedicated route with one lane each way and is not a guided busway.
Auckland is a sprawly city of 1m people somewhat similar to Perth in
density. The busway is performing well in terms of patronage, and park
and ride stations are full especially at the northern end. The bulk of
patronage growth has been through car and bus journeys to the stations
along the way. The route runs parallel to an existing 6 lane motorway
and has been built by Transit New Zealand - the national highway
building authority - which is very experienced at contract management.
I mention all of this in preamble to the fact that the most
disappointing aspect of this is that the per km cost has been around
three times that associated with equivalent light rail and the land use
footprint of the corridor is considerably larger.
The Brisbane situations is complex and has involved the expansion of
both rail and bus services. The busway in part functions to get buses
past highway congestion and performs this role quite well. I understand
operating costs have been higher than projected, but I am unsure as to
the extent of this.
As someone with considerable experience in transport debates (and
someone who helped ensure the above project proceeded) I am concerned to
see busway proponents in this country and elsewhere adopting the kind of
misleading and hyperbolic claims I normally associate with the highway
lobby. Curitiba for example is often cited as a bus-based system; they
have the same issue of capacity on routes versus flexibility and to
achieve high capacity their trunk buses operate very much like trains.
A large study team from New Zealand went to Curitiba a couple of years
ago and produced quite a detailed report on a wide range of urban
The best place for information on impacts of road versus rail
construction is Europe, where there has been significant construction of
both major roads and major rail projects in the last two decades. In
general impact of construction relates to the land footprint, rather
than mode. This is particularly important in cities, because a major
economic rationale for cities is to maximise the opportunities for
interaction while minimising distance travelled. Highways have very
limited peak volumes in relation to the land they occupy, when compared
with rail especially, and so have much higher adverse economic impacts
in urban settings where peak corridor volumes are high.
As to tunnelling - its really hard to generalise. For highways it is
generally a matter of relative cost. The impacts are considerably less
than cut and fill for example! Tunnelling costs tend to be higher than
daylighting (though this depends on the cost of fill disposal) but the
local impacts are far far less. Whether tunnelling is viable depends on
huge range of factors that are highly localised (eg geological
