Found this interesting article where some experts argue that Sydney train problems could be fixed by halving car registration and removing tolls. It reverses the normal mantra in favour of active and public transport. My take is that the article is asking the wrong questions. The key question that should be asked is “Why do we continue to allow Australia’s mega cities to grow instead of creating new, properly planned cities?” This post looks at other questions that might be asked if we want to make the transport systems of Australian mega cities more workable.
The transport systems of mega cities like Sydney are becoming more and more onerous as population and area grows. Commute time is growing and growing. It is a particular problem for people who do the service jobs in places like the CBD. For these people the gentrification of inner city ex working class areas means that low paid service workers have to travel a long way to find accommodation that they can afford. (Years ago the SMH commented that teachers and police who work in the CBD have to go over 40 km out from the CBD to find affordable housing.) Part of the problem here is that we have lost the moziac of high and low income residential areas and replaced it with large class areas, something that drives low income people to the fringes of the mega city. (In the past places like Balmain provided places where low income workers could live close to where they worked in the CBD areas.)
Transport systems have to have enough fixed and mobile capacity to cope with peak hour traffic. The following graph is based on Brisbane traffic to the CBD but similar patterns would apply to other large cities.
Better managing of peak hour traffic is a key strategy for improving transport.
The above problems inspired the following list of questions:
- Do all these people really need to travel during peak hours?
- Can some of these people work at or near home for at least one day a week?
- Could some of these people work in satellite offices closer to home and/or places where they travel against the main flow of traffic during peak hours?
- How do we create places where service workers can live close to places like the CBD?
- How many people would be interested in staying close to work for one or more nights a week? (Including dongas for couples?)
- Should we move to a 7 day roster with only half the workforce going to work on any one day?
- Should we ration travel into the CBD? (Rationed by time slot?)
- Should we ration the number of jobs available in the CBD?
- Why do we allow people to travel in family sized cars with no passengers during peak hours? (For Greater Brisbane on Tues 9/8/11 82.5% of car commutes were driver only with 64.5% of commutes using cars.)
- Why aren’t we developing standards for “commute cars” designed to carry one or two people? (Think of cars one passenger wide that are narrow enough to travel two abreast in a lane and short enough to angle park in a normal street.)
Some of you may want to add to the list or comment on some of the possibilities.
