To kick things off, former NRA President, Ian Radbone argues that we should be careful what we wish for when we demand more parking.
You want more parking? Then accept more congestion.
When I was President of the Norwood Residents Association, the two most common complaints I used to hear were both about cars: too much traffic and not enough parking. I used to respond by asking, “which do you think is worse?” because providing more parking results in more traffic. It’s what we called a wicked problem when I used to teach public policy. There’s no ultimate solution.
There’s a practically insatiable demand to drive more, and the more governments do to accommodate that driving, the more driving there is.
I’m almost 70, and all my life governments have been “upgrading” (that is, widening) roads to cope with congestion. It improves things for a while, but then it just seems to get worse than before.
One thing that does discourage driving and encourages people to use other means of getting about, is a lack of parking. Walking, cycling public transport are all more popular in the CBD because parking costs money. Where parking in free and plentiful, people drive, at least until congestion gets too bad. Then they complain about congestion, governments widen the roads, …and on it goes.
For a place like Norwood, the amount of local traffic per day can be calculated by the number of parking spaces and how often that parking space is “turned over” – how many cars use it in any one day. The formula is:
daily local car trips = number of local car spaces x number of cars that use the space x 2.
So, if an on-street car space is used by a local employee all day it would probably generate only two trips. (Perhaps four if we include the evening.) If it is on The Parade and has a 15 minute time limit during business hours it might generate sixty or more trips, i.e. more congestion. It’s funny that the employee parking we complain about actually produces less congestion than customer parking.
The same applies to off-street spaces, of course. There’s a two-hour time limit on the Council car park in Webbe Street. Let’s assume it is 50% occupied and that every driver uses it for the full 2 hours, that is it gets turned over four times a day during business hours There are about 240 spaces in that car park, so the number of trips that car park generates would be
240 spaces x 4 turnovers x 50% occupancy x 2 trips, one in, one out = 960 trips
Shorter stays and higher occupancy would mean more trips than this.
I don’t know how many of those trips would be using the George St/ Parade intersection, but it would be a lot, and I haven’t mentioned the 270 or so spaces owned by the shopping centre, which also have a two hour time limit, so another 1080 trips. And I haven’t included any afterhours trips, though congestion is not such a problem then. And then of course there’s the new car parking spaces associated with Coles, which I haven’t counted.
From time to time we hear calls for rate payers to pay for another deck to the Webbe Street car park. Just remember that if that is done, congestion will be worse.
What can we do about it? If we really want quiet streets, with lots of people walking and cycling, then actually cutting back on the amount of parking would do it. But it would require a serious on-street parking regime to strictly enforce on-street parking policies, and that would not be popular with businesses and with many residents. And The Parade’s economy relies on lots of customers driving here from other suburbs, so local businesses would not be so busy.
Another approach would be to “do an Unley”, that is, chop up streets so that they are accessible to local traffic but not to through traffic. I live on Theresa Street, which was chopped up like this many years ago. We don’t have traffic problems, and I can’t imagine my neighbours ever wanting to go back to the old days. But then try to introduce new closures and opposition arises and nothing happens. I think Donegal Street is the only other street in Norwood that has been given this treatment. Are there others?
In the meantime, I avoid (and not add to) the congestion and parking problems by walking and cycling. If I need a car, I hire one of two Flexicars based in Norwood, or hire a ute from Bunnings in Kent Town.
