Transport infrastructure projects are conceived, planned and assessed in a way that makes it difficult to properly consider their major public health impacts.
The time savings calculated in road project planning are based on incorrect assumptions about driver behaviour. Mick Tsikas/AAP

Modelling for major road projects is at odds with driver behaviour

Projects like Sydney’s WestConnex and Melbourne’s Western Distributor don't account for real world evidence of driver behaviour in estimating travel time savings.

Major development banks are funding logging, mining and infrastructure projects that are having enormous impacts on nature. Here, forests are being razed along a newly constructed road in central Amazonia. William Laurance
