The Public Transport Users Association (PTUA) is keen to make the case that it costs more to travel by public transport in Melbourne than it does by car. The PTUA says above-inflation fare rises over the last decade mean public transport now costs much more than “petrol in the car” for many trips.
The PTUA might take some moral support from this op-ed in The Age this week by journalist Gabriella Costa (the paper calls it an ‘Analysis’). Like the PTUA, she also argues that commuting by car is cheaper. She says the 9% fare increase announced this week by the Government will make driving a better option. Her contention is that, “even loosely, the maths just don’t add up” for rail:
And it’s a simple equation. A Metro daily ticket from a zone 2 station into the city? $11.90 from January 1. Petrol from home to work and back? two to three litres. Parking: less than $10 a day on the city’s edge.
Ms Costa doesn’t actually do the maths, so I have. Unless she gets her petrol for free, even on those numbers it still costs less to take the train to the city than drive! Petrol at $1.35 per litre is $4.00 a day, plus $10 for parking. Even loosely, that adds up in favour of the train! But as we all know, there’s more to the financial cost of driving than just petrol and parking, so I’ll try to do a tighter estimate.
Ms Costa’s example is based on her own circumstances. I know from her article that she lives in St Albans, near Giniver station in Zone 2. By her estimate, she’s 17 km by road from where she works in the city (presumably at The Age HQ in Spencer St). I’ll assume she commutes 220 days a year after taking rec leave, public holidays, sick leave, the odd day off, a bit of work-related travel and weekends into account. If she drove to work on every one of these 220 days she’d therefore travel 7,480 km in a year.
I’ll assume she drives the cheapest vehicle you can buy new in the small car class, a Hyundai i30. According to the RACV, operating costs of this vehicle for fuel, tyres and servicing, are 16.6 cents per kilometre, giving her an annual commuting cost of $1,224. That’s conservative because the fuel component is based on a city-country average – commuting in busy traffic is thirstier work.
Add to that parking at $10 per day for 220 days and her all up cost for a year of commuting by car to the CBD totals $3,444. That’s still quite a bit more than the cost of catching the train from St Albans, even under the new fare structure that takes effect from 1 January.
St Albans is in Zone 2, so Ms Costa could buy a myki Yearly Pass in 2012 for $2,021. That would save her $1480 compared to driving. Even if she travelled every day on a myki Daily Cap it would cost $2,438 over the course of a year, still putting her ahead by $1,000 compared to driving.
And if she lived any further out the cost of train travel would stay the same but driving would cost considerably more. If, for example, she lived in Pakenham (since she mentions it in her article) her annual expenditure on driving would increase to $6,371 p.a. because it’s 57 km from her workplace. But the cost of the train would be the same as it is from St Albans, since both stations are in Zone 2.
It’s important to note that I’ve only considered variable costs, specifically parking, fuel, tyres and servicing – I’ve taken no account of the cost of owning the car. But it makes no sense to ignore standing costs, because if she doesn’t actually have a car she can’t drive to work! The RACV says the annual standing cost of a Hyundai i30 is $5,668, made up primarily of depreciation, interest, insurance and registration.
If I assume commuting accounts for half of her total annual travel by car (i.e. she drives 7,480 km to work each year as well as doing a further 7,480 km p.a. in non-work travel), then the standing costs that should be attributed to her journey to work come to $2,834.
Add that $2,834 to the $3,444 she pays for parking, fuel, tyres and servicing and Ms Costa is up for an annual total of $6,278 for the privilege of driving to work from St Albans. Remember, a myki Yearly Pass will cost much less, just $2,021, and even a myki Daily Cap will cost her $2,438 for the year. Read the rest of this entry »
