Save 40 Minutes? Less than 15, says traffic expert.

At the NSW Upper House Inquiry into Road Tolling on 22 May, Professor
David Hensher, Director of the Institute of Transport and Logistics
Studies at the University of Sydney, was asked whether WestConnex would save
drivers 40 minutes on a trip between Parramatta and Sydney Airport.

Professor Hensher replied:

“It is too high; I do not believe it”.

Earlier the same day, Labor MLC John Graham had tabled an RMS document
showing that drivers would save around 15 minutes.

Professor Hensher said the prediction was unrealistic:

“15 minutes [would be] the best-case scenario … These are the optimistic numbers”.
