    EXECUTIVE SUMMARY

    Trafficworks has been engaged by Amex Corporation to undertake a traffic impact assessment of

    the proposed residential development for the parcel of land that falls between Dohertys Road to

    the north, Tarneit Road to the east, Leakes Road to the south and approx. 820m west of Tarneit

    Road to the west, in Tarneit.

    Part of the land is segregated by the proposed Regional Rail Link which will provide a new track

    between West Werribee Junction to Deer Park, then along the existing rail corridor from Sunshine

    to Southern Cross Station. As part of this project, a new train station within 2km of the site will be

    developed at Tarneit.

    The southern precinct (south of the Regional Rail Link tracks) is proposed to have access via

    Leakes Road at two locations. The northern precinct (north of the Regional Rail Link tracks) is

    proposed to have access via one location at Tarneit Road and one location at Dohertys Road.

    Amex Corporation owns approximately 120ha over two titles on the west side of Tarneit Road,

    between Leakes Road and Dohertys Road. This land falls within Precinct Structure Plan (PSP)

    1089 – Tarneit North. The Growth Area Authority (GAA) is undertaking a number of background

    technical studies in the Wyndham North area and has yet to release the findings of the PSP.

    A Traffic Impact Assessment was carried out to:

    • determine traffic generation and distribution associated with the proposed residential

    development and the impact of the generated traffic on the internal and the external

    road network;

    • review the availability and proximity of sustainable transport options;

    • identify any necessary mitigating works.

    It has been identified that the proposed development:

    • would not adversely affect traffic conditions on the adjacent road network; and

    • would generally comply with the relevant traffic requirements set out in Austroads, Council Planning Scheme and GAA’s Engineering Design and Construction Manual for Subdivision in Growth Areas April 2011 once the suggested remedial works are undertaken.

    A summary for the site and the proposed development is shown below.

    Treatments:Treatments:Treatments:Treatments: The following treatments are recommended prior to the duplication of

    Leakes Road, Tarneit Road and Dohertys Road:

    • the East - West Connector and Tarneit Road intersection up to the completion of stage 15 of the anticipated development program will be give-way controlled with a channelised right turn short (CHR(S)) treatment and an auxiliary left short (AUL(S)) treatment on Tarneit Road;

    • the East - West Connector and Tarneit Road intersection be signalised in year 7 (calendar year 2022) of the development after the completion of stage 15 of the anticipated development program;

    • traffic signals will be required as soon as the East - West Connector and Tarneit Road intersection becomes a cross intersection where the eastern leg of the intersection is built by others;

    • the Western Access Street 1 and Leakes Road intersection be give- way controlled with a channelised right turn short (CHR(S)) treatment

  • 114430: Amex Site Residential Development, Tarneit – Traffic Impact Assessment Final: 21/06/2013

    and a basic left (BAL) treatment on Leakes Road;

    • the Eastern Access Street 1 and Leakes Road intersection be give- way controlled with a channelised right turn short (CHR(S)) treatment and a basic left (BAL) treatment on Leakes Road;

    • the North - South Access Street 2 and Dohertys Road intersection is proposed to be give-way controlled with a channelised right turn short (CHR(S)) treatment and an auxiliary left short (AUL(S)) treatment on Dohertys Road.

    along Tarneit Road, Leakes Road and Dohertys Road at the proposed

    intersections.

    Other Issues:Other Issues:Other Issues:Other Issues: It is recommended that the following be undertaken to the development

    internal road layout:

    • design of internal roads is based on GAA’s Engineering Design and Construction Manual for Subdivision in Growth Areas, April 2011;

    • incorporation of the Public Transport – Guidelines for Land Use and Development for bus routes and liaison with the Department of Transport regarding bus route and bus stop locations;

    • installation of traffic calming devices along long straight sections of road;

    • the location of intersections should be designed to meet the required sight line requirements;

    • any landscaping within the verge in close proximity to an intersection should not obscure drivers’ line of sight.
