of the traffic, transport and access assessment. It describes the existing environment, identifies potential impacts during construction and operation, and provides measures to mitigate and manage the impacts identified. Further information is provided in Technical Working Paper 1 (Transport, Traffic and Access). The SEARs and MDP requirements relevant to traffic, transport and access are listed below. Full copies of the SEARs and MDP requirements, and where they are addressed in this document, are provided in Appendices A and B respectively. Reference Requirement Where addressed Key issue SEARs 1 Transport and traffic 1.1 The Proponent must assess construction transport and traffic (network, vehicle (including freight traffic) pedestrian and cyclists) impacts, including, but not necessarily limited to: (a) a considered approach to route identification and scheduling of construction vehicle movements, with particular consideration of Chapter 8 and traffic impacts and transport movements outside standard section 5.1.5 of Technical Working Paper 1 construction hours including cumulative impacts; (b) the indicative number, frequency and size of construction related Chapter 8 and vehicles (passenger, commercial and heavy vehicles, including section 5.1.7 of Technical spoil management movements); Working Paper 1 (c) construction worker parking; Chapter 8 and section 5.1.4 of Technical Working Paper 1 (d) the nature of existing traffic (types and number of movements) on Sections 9.2.2 (traffic construction access routes (including consideration of peak traffic volumes), 9.2.5 (active times, pedestrians and cyclists and parking arrangements); transport) 9.2.6 (parking) (e) access constraints and impacts on public transport, pedestrians Sections 9.3.4 and 9.3.5 and cyclists (infrastructure and services); (f) the need to close, divert or otherwise reconfigure elements of the Sections 8.3.3, 8.6.5 and road, pedestrian and cycle network associated with construction 9.3.1 of the proposal and the duration of these changes; (g) impacts to on street parking, including for residents and Section 9.3.7 businesses; (h) cumulative impacts on the road, pedestrian and cycle network Section 9.5.1 from other key infrastructure proposals including but not limited to the Botany Rail Duplication and New M5. 1.2 The Proponent must assess (and model) the operational transport impacts of the proposal, including: (a) forecast travel demand and road traffic volumes for the proposal Sections 9.4.1 (traffic and the surrounding
