Environmental Statement volume 4 - Chiltern Evergreen3

Baseline Conditions4.7.6 Sources of information that will be used to define the baseline conditions areas follows:• existing public transport services and routes (Oxfordshire CountyCouncil);• national cycle network and regional/local cycle network (Sustrans andOxfordshire County Council);• Public Rights of Way (Oxfordshire County Council);• personal injury road accident data (Oxfordshire County Council);• existing station footfall data (CRCL); and• traffic flow data for surrounding highway network (Oxfordshire CountyCouncil and Highways Agency TRADS database).Surveys Required4.7.7 Additional surveys will be carried out where there is insufficient existingbaseline information available from other sources. These will be confirmedonce the scope of assessment has been agreed.Future Forecasting4.7.8 Station footfall data will be identified by CRCL and used for the futureforecasting. The information will establish the projected number of passengersat each station along the route together with information on modal share andtrip origin /destination. The data is forecast for 2015 (based on Opening Yearof 2013 with demand increased to 100% over 2 years).Highway Impact4.7.9 The impact of the scheme related traffic will be assessed on the surroundinghighway network against the baseline conditions. The assessment will likelymake use of Oxfordshire County Council’s SATURN model, which was builtin 2008. In respect of Water Eaton Parkway and Bicester, more detailedassessment will be undertaken to assess the impact of the scheme in theimmediate vicinity, if required.Evaluation Criteria4.7.10 The significance of effects will be determined using appropriate criteria set outin the following tables.Table 4.12Magnitude of EffectSubject AreaMagnitude of EffectMajor Moderate Slight NegligibleEffect onwalking andGreater than+/-25%Up to +/-25% changeUp to +/-10% changeNo measurable change fromexisting mode share or habits.ENVIRONMENTAL RESOURCES MANAGEMENT 62 CHILTERN RAILWAYS LTD
