Roe Highway extension - traffic modelling

Submitted by Louise Sales on Tue, 20/09/2011 - 15:20

On 1st September Lynn asked the following question without notice in Parliament:

(1) Can the minister confirm information published in the “Roe Highway Extension Public Environmental
Review Volume 1”, which states that —

(a) forecast daily total traffic flows, as shown in figure 2.2–6 on page 28, on Leach Highway would be virtually unchanged in 2021 whether Roe 8 is built;

(b) congestion on South Street and North Lake Road is likely to be a problem only in peak hour; and

(c) the congestion on South Street and North Lake Road in 2021 is unlikely to be improved from that currently experienced if Roe 8 is built and in some cases will be worse, especially at Stock Road and Murdoch Drive?

(2) What other strategies were investigated to reduce traffic congestion at peak times?

Today the Government finally provided a response:

ROE HIGHWAY EXTENSION — TRAFFIC MODELLING

Question without Notice 691 — Supplementary Information

HON SIMON O’BRIEN (South Metropolitan — Minister for Finance) [5.12 pm]: On Thursday,
1 September 2011, Hon Lynn MacLaren asked question without notice 691 about the Roe Highway extension traffic modelling. I seek leave to have a correction to parts (1)(b) and (c) and (2) tabled and incorporated into Hansard. By way of brief clarification, in this case and with the previous question, although it is a correction to the answer that was provided, it is not that incorrect information was provided at that time; rather, the answers as provided on those occasions were incomplete because they did not include the information that I am now tabling.

Leave granted. [See paper 3729.]

The following material was incorporated —

(1b) Moderate to heavy congestion either side of peak hour.

(1c) Intersections on Stock Road, to the south of Roe Highway, will have increased congestion when Roe Highway is extended.

(2) Major road upgrades are being planned or considered in the south western metropolitan area.
