Subject: Eco Park - LinSIg Modelling

Caroline,

Thank you for the file note explaining the traffic flow differences in the various modelling tools. Highways England has now

undertaken a review of the note and its appendices and our comments ae set out below.

Highways England is content that accurate traffic flows have been calculated, based on agreed trip generation and distribution

methodologies for weekday peak and Saturday peak profiles. The weekday leisure and employment proposals match those

previously agreed, and we accept that weekday football matches will not generate traffic during the weekday peak

hours. During a Saturday peak, football match traffic has taken account of a maximum capacity football match attendance, with

67% of football arrivals assumed to travel during the 1400-1500 Saturday peak hour, and 76% of football departures occurring

during the 1700-1800 Saturday peak hour. Again, these conclusions are agreed.

Vehicles have been converted into PCUs using a value of 2.3 PCUs for HGV. We have undertaken spot checks on values and

believe these have been calculated correctly.

The traffic figures provided show development trips with each element of the proposals distributed over the highway network.

Highways England welcomes the updated set of traffic figures, which have been used to check against traffic flows included in

the various traffic models.

Based on the comments above, Highways England is satisfied that further modelling can be undertaken based on these flows.

Site Access Junction (Signal Controlled)

Highways England has previously provided comments on the signal controlled access junction, as ‘sticky notes’ on a PDF drawing

sent by email on 23 August 2017. If these comments result in further changes to the access layout, these changes will again

need to be reflected in both the LinSig and S-Paramics traffic models.

Noting that changes are already likely to be needed to the S-Paramics model, due to more recent Highways England comments

on the site access design and LinSig model, comments have been provided on the S-Paramics models received on 02 August

2017.

S-Paramics Model

These comments are interim pending finalisation of the site access layout and the final junctions form incorporation into S-

Paramics.

The most recently supplied modelling report (“E161-DOC13 LMVR & Forecasting Issue 4 - FULL REPORT.pdf” has been reviewed

along with the associated modelling files comprising Scenarios 1 to 10. This has confirmed that all issues raised previously by

CH2M/Highways England have been resolved, or that satisfactory reasoning has been provided in the modelling report, namely:

• GA Look-Next parameter has been added to most circulatory sections at Oldends Lane Roundabout;

• The A419 Bristol Road/Boakes Drive mini-roundabout has been added to the network;

• GA Look-Next parameter has been added to the circulatory link opposing Ebley Road at Horse Trough Roundabout;

• Horse Trough Roundabout coding has been amended to improve give-way behaviour from the Bath Road entry.

Examination of the base model calibration and validation results for the time periods modelled shows that observed and

modelled turning movements compare well, and that journey time validation along the A419 corridor meets DMRB acceptability

criteria. Observed and modelled queue lengths also show a reasonable correlation. It is therefore considered that the base

model can be accepted as a basis for forecast testing.

2

A review of the forecast models supplied confirms that they are consistent with the revised and updated calibrated/validated

base model. Additionally, a number of previously raised concerns relating to the forecast models have also now been

addressed, as follows:

• Link modifiers on the Ebley Road entry to Horse Trough Roundabout are now consistent with the base model;

• Inter-green timings have been amended at the proposed access junction (although see comments below);

• Entry link lengths on Oldends Lane and Bath Road have been extended with all queuing now contained within the

network.

The acceptance of the base model and the above, should mean that the forecast models can now be relied upon to provide a

reasonable prediction of future changes in operational conditions within the modelled network. There is however a need to

update the traffic scenarios to match those now agreed Highways England. These include an Opening Year scenario of 2021.

Once the A419 site access junction is agreed and correctly replicated in both LinSig and S-Paramics, Highways England will again

review the results and provide the necessary comments and/or final recommendation. For local highway network junctions,

comments should be sought from GCC.

If you would like to discuss any of the points set out below, please do not hesitate to contact me.

Regards

Nigel Gorski

Nigel

I attach File Note E161-FN47 which explains the difference between the spreadsheet and LinSig model flows, and

also sets out the spreadsheet model flows by element.

Please could you look through that and let me know if you have any comments or queries, before we go on to the

further modelling.

Thanks & Regards
