(a)-(h) The PATHS was conducted for the primary purpose of obtaining data for the calibration of the new Perth Transport Model (PTM). In this context, comprehensive analysis of the PATHS data has been undertaken and will be published in due course.
The timeline for the initial publication of PATHS data reflects internal data investigations and calibration to ensure reliability for secondary purposes.
A review of future data requirements will be conducted in due course.
