The functions of the Logistics Centre 1 are (i) to assist in the management of construction/delivery vehicle flow and access to the main Olympic Site in Stratford, East London by enabling vehicles to be assembled and called to the construction site in the most efficient manner to assist the Olympic Site construction and (ii) to allow security checks of vehicles to be undertaken before they reach the Olympic Site construction site. 1.2 Scope and Objectives of the Report This Transport Assessment (TA) supports a Planning Application for the proposed Logistics Centre to the planning authority, Epping Forest District Council. The traffic and highway aspects will be considered by the relevant highways authorities, namely the Highways Agency (HA) for M11 impacts and Essex County Council for Chigwell Lane impacts. The TA has been prepared in accordance with the Brief issued by ODA (agreed with the HA before the commencement of the commission) and in “ – accordance with the Guidance on Transport Assessment Communities and Local ” – “ ” Government and Department of Transport (March 2007 version the Guidance ). The TA draws upon, and analyses, traffic data collected in and 2007, accident data for the last 3 years and topographic surveys. The objectives of the TA are to assess (i) the adequacy of the transport system to meet travel demand arising from the Logistics Centre and (ii) the impacts of the Logistics Centre on the surrounding transport and highway network.

Beyond December 2013, the Centre will not be used and will be returned to its present open land form. The ODA will initially operate the Centre at a low vehicle flow and will build to capacity (a maximum of 130 vehicles may be parked at the site) as operational familiarity is gained to allow increase to full capacity The proposed Logistics Centre 1 is located on the M11, approximately 6.5km south of Junction 6 of the M11 with the M25 and 2km south of Junction 5 at Chigwell Lane. The main entrance to the Olympic Site is located about 12km to the south and is reached by the M11, the A406 and the A12 as illustrated in Figure 2.1.
