Stephen Metcalfe – 2016 Parliamentary Question to the Department for Transport

The below Parliamentary question was asked by Stephen Metcalfe on 2016-02-24.

To ask the Secretary of State for Transport, when the data used to predict traffic flow at the proposed new Lower Thames Crossing – Option C was generated; and whether that data is publicly available.

Andrew Jones

The traffic modelling carried out to inform the assessment of alternative options has been based on an extensive assessment of travel and road usage patterns. The underlying data was collected through extensive observations and roadside surveys as part of the London Area Transport Surveys in 2001. This data was updated in 2009. A ‘Review of Lower Thames Crossing Options: Model Capability Report’ which was produced in 2013 examined the suitability of the traffic modelling, including the use of the 2009 data, for strategic assessment of the Lower Thames Crossing options, and this report concluded that the overall model performance was suitable for options assessment at this stage. This report is available online at gov.uk.

Further detail on the recent modelling for Options A and C is available in Volume 5 of the Scheme Assessment Report which can be viewed on line at the consultation website on the project website via www.lower-thames-crossing.co.uk. It is also available as a hard copy at the public information events and local libraries as a reference document but not to be taken away. Highways England can also send out a copy to anyone who requests it through the Highways England customer contact centre on 0300 123 5000.
