Response

Information provided

1. Copies of all traffic model information relied on within the DCO submission

The DCO document library contains all the information relied upon during the DCO examination. For the traffic model information please see the documents titled:

· REP1-010 - 9.13 Traffic Forecasting Report

· APP-136 - 7.4 Transport Assessment Report

· REP2-011 Deadline 2 Submission - 9.16 Transport Assessment Supplementary Information Report

· REP4-041 Deadline 4 Submission - 10.7 Transport Assessment Addendum - Changes to application

2. Copies of and / or access to the highway assignment and microsimulation models relied on within the DCO submission.

Please see the zip file titled 'Q2 information' which can be downloaded from this link

EIR2024/00497.

The files contained in the 'SATURN' folder are the highway simulation models. In the filenames TS1 = AM peak, TS2 = Inter peak and TS3 = PM Peak. The files contained in the 'S-Paramics' folder are the microsimulation models.

The files relate to the revised DCO scheme submission (without A245 eastbound widening), as this is the scheme which was consented. Therefore, the results from these files match with the Transport Assessment Addendum, but not the Transport Assessment itself nor the Traffic Forecasting Report.

Please note that the only way to access these files is to purchase specialist software. SATURN software is distributed by AtkinsRéalis. 'S-Paramics' distributed by Systra. If you are unable to purchase the software please let us know so that we can arrange for you to view the files in person.

3. Copies of any traffic data used to develop the highway assignment and microsimulation models

Please see the 2 PDF's which can be downloaded from this link

EIR2024/00497. They are tiled:

· Stage 3 - Transport Data Package - M25J10-A3.docx

· Stage 3 - Transport Model Package - M25J10-A3.docx

Please also see the document titled 'REP1-010 - 9.13 Traffic Forecasting Report' referred to in our response to question 1.

4. Copies of the list of assumptions used to develop the highway assignment and microsimulation models
