Use of a Driving Simulator to Assess Driver Response to the NorthConnex Tunnel Design Features

How do drivers respond to the iconic tunnel design features included in the NorthConnex road tunnel project? What were the objectives of the designs and have the designs achieved these objectives? How do the designs affect driver behaviour?

The webinar explains the two key elements of this work – the validation of the UNSW driving simulator as a means of assessing road tunnel design features, and the use of that simulator to test driver response to the design features included in NorthConnex. The presenters explains the logic of the trial methodology, whereby the driving behaviour of trial participants was assessed in the actual tunnel as well as in the simulated tunnel – the latter both with the design features included and with the features excluded.

The work sought to determine whether the design features enhanced the driver experience without an adverse effect on safety. The work demonstrates that the driving simulator is a valid tool for assessing tunnel design features and therefore provides a platform to inform design features in new tunnels but also a tool to assess how such designs may help to mitigate operational issues in existing tunnels.

The webinar is presented by Prof Michael (Mike) Regan, Dr Prasannah Prabhakharan, Julius Secadiningrat, Jack Mazaraki, Nicholas Rozenauers, Nigel Casey and Richard Merrett.
