INDUCED travel due to changes in the transport network is a well-known phenomenon. For many years, it was ignored in transport modelling, by accounting only for re-routeing of trips rather than mode shifts or origin and/or destination changes. Nowadays, most modelling includes it, thus producing variable trip matrices between scenarios rather than fixed ones. AContinue reading “Induced travel: how quickly do people adapt?”

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 (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.
