Infrastructure Victoria’s draft 30-year infrastructure strategy is confusing and disappointing. It needs to embrace much stronger commitments to change. We must urgently eliminate harmful emissions and rein in our ecological footprint; IV’s strategy will not help us achieve this.

North East Link – the perfect storm
North East Link is shaping up as the biggest mistake of the Andrews government’s autocratic approach to transport infrastructure.
It has many problems that will eclipse those of the West Gate Tunnel.
The taxpayer will take the risk of its failure to attract traffic, and it’s not worth the massive impacts on the local people and environment.
Tunnel Tales (3 of 3) – Rubbery figures: why the West Gate Tunnel doesn’t stack up
The West Gate Tunnel doesn’t stack up and it should never have been approved.
Its economic benefits were overstated in the business case. Rather than $1.30, the project will probably return only $0.60 per dollar invested.
It doesn’t stack up financially either. Transurban needs $2.6 billion from the public purse, plus more toll revenue from CityLink, to make it work.
Tunnel Tales (2 of 3) – transport modelling and the ‘single loop’
Transport modelling for the West Gate Tunnel was not done to prescribed standards.
It contains illogical methodology and errors that probably resulted in significant over-estimates of future traffic on the project.
It also can’t be shown to be mathematically stable, which is a fundamental requirement of such modelling. It therefore shouldn’t have been used for the cost-benefit analysis, nor as a basis for the environment effects statement.
The same is true for East West Link and North East Link, which used the same modelling processes.
Transport modellers must take heed of these issues. Concurrent peer reviews must be compulsory.
It’s time to lift the game and do it properly.
Tunnel Tales (1 of 3)
The Government’s assessment of the West Gate Tunnel contained significant errors in the transport modelling and the cost-benefit analysis that made the project seem a lot better than it was. It should never have been approved, and I predict that when it eventually opens it won’t deliver the claimed benefits.
Victoria’s broken transport planning ‘system’
Let me be very clear about this – the system of rational and objective planning for transport is completely broken in Victoria.
Politics has trumped planning, and there’s no guarantee that the chosen investments are the right ones.
It’s nothing short of pork-barreling in the extreme.
