According to a report in The Age last month, new research published in the latest issue of Australian Planner shows that higher suburban densities are not a precondition for vastly better public transport. Reporter Andrew West says:
City dwellers have been presented with a false choice – live in apartments and enjoy good public transport or retain the house and land and rely on cars
The research by Dr John Stone and Dr Paul Mees contends that it is not necessary to intensify land-use across the whole city before significant improvement in both patronage and economic efficiency of public transport becomes possible.
They say the contribution made by urban consolidation “to recent public transport patronage growth is modest and makes little impact on the density of the whole urban region”. Most residents of Australian cities will continue to live in houses and suburban subdivisions that are already built so “alternatives to the car will need to be effective at existing urban residential densities”.
They argue instead for a ‘networked’ model of public transport. Improving the way existing public transport resources are managed – especially by providing higher frequencies and improving coordination between services and between modes – will yield significantly higher transit patronage in the suburbs without the need for broadbrush increases in density.
I’ve argued before that increasing residential density, by itself, will not necessarily increase public transport patronage significantly, much less shift travellers out of their cars in large numbers.
I’ve also argued that there are generally better gains to be had from using existing resources more efficiently rather than relying on strategies based around huge new infrastructure investments or massive land use changes.
And I think the idea of networking public transport is absolutely critical. By embracing transfers, networking provides faster travel paths to all parts of the metropolitan area than is possible by radial routing.
However it’s not obvious to me that ‘networked’ public transport, by itself, would have the sort of major impact on mode share in the suburbs implied by The Age’s report. I can see that it would make public transport much better for existing users and I’ve no doubt it would increase patronage, but I’m not persuaded that it would be enough to address the ‘false choice’ that The Age says Melburnites have been presented with.

I argued yesterday there might be potential to shift a small but important proportion of workers who live and work in the suburbs out of their cars and on to bicycles. This is a somewhat novel view as most of the attention given to commuting by bicycle has focussed on how to increase work trips to the CBD.
The suburbs are an important potential ‘market’ because, unlike commuting to the city centre, the great bulk of suburban bicycle trips to work would be in lieu of the car, not public transport.
I also indicated yesterday that I would look further at possible concrete actions that could be taken to advance greater suburban bicycle commuting. Here are my early thoughts.
The key deterrents to cycling concern safety, compulsory helmets, security and personal hygiene. A possible way of addressing these obstacles could go something like this. Read the rest of this entry »
