(a) The member may not be aware that the previous state Coalition Government had agreed to allow 36 metre vehicles to use Brookton Highway. However our Government stopped that expansion so through the suburbs of Roleystone and Karragullen the Highway is limited to long vehicles up to 27.5 metres in length. Long Vehicles consist of short road trains, B doubles and rigid trucks towing a trailer.
Through the suburbs of Roleystone and Karragullen the Highway is approved for all types of long vehicles up to 27.5 metres in length. Long Vehicles consist of short road trains, B doubles and rigid trucks towing a trailer.
To enhance road safety Main Roads requires laden long vehicle type road trains, when travelling west towards the metropolitan region, to leave Brookton Highway at Karragullen and use Canning Road and Welshpool Road (east) to gain access to the Metropolitan area.
To further reduce the number of heavy vehicles on Brookton Highway, Main Roads has implemented processes to encourage the use of rail for the transport of grain between grain receival centres in the Great Southern and the Metropolitan region.
(b) As part of the AusRAP process there are two outputs - crash mapping and a Star Rating which is an assessment of the road attributes and the relative risk they pose to a road-user. It rates various road attributes and essentially gives them a score (e.g. seal width, carriageway etc).
The star rating does not consider exposure (traffic volumes) and therefore a road which carries 50 vehicles per day will be assessed the same as a road that carries 5000 vehicle per day. Main Roads uses a different criteria for prioritising locations that require remedial works, which is based on exposure. Therefore different roads and road sections will be flagged by the Main Roads process rather than the AusRAP rating. One of the key criteria used by Main Roads is crash data.
A review of crash data over the last five years (January 2003 - December 2007) indicates there have been a total of 43 crashes on the 7 kilometre section of Brookton Highway between Peet Road and Canning Road. The overall safety performance for this section of the Highway is reasonably good and in terms of crashes per million vehicle kilometres of travel, compares favourably to other semi-rural, undivided roads across the State.
(c) In March 2005 Main Roads completed a Road Safety Review on Brookton Highway, which included an assessment of all the bus embayments between Albany Highway and Chevin Road. The Review recommended the upgrading of 8 bus embayments, the installation of 2 new embayments, as well as a number of other low cost treatments such as the installation of advance warning signs, installation of yellow pavement markings and clearing of vegetation to improve sight distances.
To improve traffic flow and enhance road safety a number of the low cost recommendations were undertaken and the first of the embayments, situated near Lefroy Road, was upgraded early last year. Upgrading of the other embayments will be addressed as funding becomes available.
