(1) Yes
(2) Yes
(3) Yes. The key outputs of the traffic modelling are [See tabled paper no....] and are also publicly available on Western Australian Planning Commission website -

.
(4) Not applicable.
(5) Refer to answer to Q3.
(6) Not applicable.
(7) Yes.
(8) Modelling was undertaken in 2009 using the Main Roads' Regional Operations Model and the City of Perth's SATURN model. Both of these models indicated that for a forecast year of 2031, the Graham Farmer Freeway would have increased traffic volumes in the AM and PM peak attributed to general traffic growth, planned developments within the Perth CBD (including Perth Waterfront), localised network changes proposed by the City of Perth and wider regional road network changes proposed by Main Roads WA (MRWA). Modelling indicated that by 2031, Graham Farmer Freeway will be at capacity during AM and PM peak. These projections were based on the Tunnel being two lanes in each direction.
(9) Yes.
(10) The modelling results showed some increases in forecast traffic volumes on roads around Graham Farmer Freeway, such as Lord Street, East Parade, Plain Street, Roe Street, Sutherland Street and Bulwer Street. However, the projections indicated that these roads were generally to be within capacity during peak periods.
(11) The outputs from the 2009 modelling exercise did not extend south of the Swan River. However, changes to the road network in this area, and distribution of traffic, would have been accounted for within the MRWA ROM modelling.
The Department of Transport and the City of Perth are currently leading a strategic transport planning exercise for the Perth CBD which will include updated traffic modelling for the CBD and peripheral road networks.
