A separate report, the Parramatta Light Rail Operations Traffic and Transport Technical Assessment Report (OTTTAR) report sets out an assessment of the anticipated traffic and transport implications of the operation of the project. The objectives of the CTTIAR are to: Assess the traffic and transport impacts, including pedestrians, cyclists, public transport and parking and conditions for the existing corridor and connections along the project corridor Develop mitigation and management measures to minimise the impacts identified, providing the overarching principles and procedures for implementing traffic and transport management controls. The structure of the report first addresses the prevailing transport conditions throughout the project and provides a framework for procedures and protocols for mitigating and managing impacts on the transport network. These include: Providing safe and accessible facilities for pedestrians and cyclists during construction for all worksites Maintaining public transport services past the worksites (where required), minimising delays on existing bus services through the implementation of appropriate detours and general traffic measures Managing general traffic through and around the worksites, with consideration of local and regional traffic Implementing appropriate haulage routes for construction traffic Minimising the impact of construction on residents and businesses. The project corridor was divided up into five precincts to facilitate the application of the protocols listed above in more detail. The precincts are described as follows: Precinct name Precinct extent Between the Westmead terminus north of Westmead Railway Station and the Parramatta Westmead River crossing west of the Cumberland Hospital site west of Parramatta Park. Between the Parramatta River crossing west of the Cumberland Hospital site, Church Parramatta North Street at Board Street and south to Victoria Road (north of Prince Alfred Square). East of Parramatta Park and south of Victoria Road and east to Purchase Street/ Noller Parramatta CBD Parade, inclusive of the Robin Thomas Reserve. Between Purchase Street, Parramatta in the west and east to the stabling and Rosehill and Camellia maintenance facility in Rosehill and north to the Parramatta River north of Camellia. The existing heavy rail line north of the Parramatta River in Rydalmere to and including Carlingford Carlingford Railway Station. Testing the impacts of construction Extensive traffic modelling has been used to test the potential impacts of construction traffic on the road network and to investigate the benefits of candidate mitigation measures. A mesoscopic traffic model of the area was used to investigate the broader network impacts. The N102531 // 14/08/2017 Final Report Issue: A i Parramatta Light Rail, Construction Traffic and Transport Impact Assessment Report modelling analysed and compared the 2016 base year traffic conditions with each of the proposed construction phases (enabling works, plus two construction phase scenarios) for the following time periods: AM peak: 7 am to 9 am PM peak: 4 pm to 6 pm. The traffic modelling data was supplemented with extensive parking surveys, public transport network data and walking and cycling information to enable an assessment of the entire, integrated transport system. Construction activities The overall process for constructing the project would be as follows: Detailed field investigations (including geotechnical, heritage, contamination and
