About the project

On 28 November 2016 The Government announced that capital funding of £175m over four financial years would be made available to local authorities to improve the safety of 50 of the highest risk A roads sections in England.

The 50 routes were based on analysis by the Road Safety Foundation.  

In January 2017, BCC was informed that a 9.2km section of the A40, between Stokenchurch (junction M40) and West Wycombe (junction with A4010) had been identified as one of the routes with 10 Killed or Seriously Injured (KSI) collisions in the 3 year period 2012-14. This was a rise in the previous 3 year period (2009 - 2011) and as a result BCC was invited to bid for funding.

  • Site 11 – A40 West Wycombe Road, near George Road
  • Site 14 – A40 Oxford Road / Ibstone Road

Due date

Completed within 2017-18 financial year

Notes

Signing and vegetation clearance work undertaken in 2017-18 prior to formal announcement of DfT funded safety scheme.

Improve pedestrian safety at crossing point on the A4010 (northern arm) of the Pedestal Roundabout.

Due date

This is anticipated October/November 2018

Replacement of the flashing lighting units on zebra crossing to improve appearance.

Due date

Pending lead-in periods Nov 2018

Improved warning signs and bollards on A40 at bend on eastbound entry to West Wycombe. This is to increase driver awareness and appreciation of bend.

Due date

Programmed Jan 2019

Improved warning signs on A40 prior to junctions to increase driver awareness of junctions and turning farm traffic.

Due date

Programmed Nov 2018

To improve existing footway alongside the A40.

Due date

Programmed October 2018.

Notes

Location identified by Cllr Darren Hayday - footway in cutting in need of siding out and vegetation cutback.

Initial assessment carried out Sept 2018.

This is a potential scheme identified to provide pedestrians with an alternative route remote from the A40 with no additional distance, but significantly less traffic and lower speeds. 

Due date

N/A

Notes

There appears to be initial merit in further investigation. There will be significant vegetation cut back to achieve footway. Part of the route may be unachievable due to level differences as carriageway is within small steep cutting (approx. 200m length). However, this section is on a straight. Remainder of route appears initial viable either through use of existing verge or carriageway width.

Footway works to improve route into Water End Road for school pedestrians to avoid walking within carriageway adjacent to junction triangle island.

Consideration also to be given to coloured edge surface treatment as a formal footway is not achievable on approach to school due to narrow carriageway width.

Due date

N/A

Additional vegetation clearance works on sections of the A40 including:

  • Layby area between Mudds Bank layby and A40 (trees to remain, but low level vegetation to be cleared
  • Siding out of carriageway on southern side between Studley Green and Stokenchurch

Due date

N/A

Notes

Layby Area Identified September 2018 following discussion between TfB Area Manager and Stokenchurch Parish Council, agreement made to remove vegetation to enable clear view into layby to prevent anti-social behaviour and improve visibility on approach to left turn into layby.

This will improve safety within layby and also prevent hard braking where drivers cannot see clearly into layby on approach.

Upgrade of signalised pedestrian crossings from old style pelican crossings to new Puffin Crossings, incorporating nearside pedestrian signal units, crossing sensors. This would also include other safety improvements such as widening of norther footway.

Note the most westerly crossing in Stokenchurch is already a Puffin Crossing and therefore no further works proposed.

Due date

Anticipate Jan 2019

Provision of central refuge island and build-out of western corner of junction to improve pedestrian safety walking along A40.

Due date

Anticipated Construction 8th October 2018 - Start date under road closure

Upgrade of signalised pedestrian crossings from old style pelican crossings to new Puffin Crossings, incorporating nearside pedestrian signal units, crossing sensors. This would also include other safety improvements such as widening of norther footway.

Note the most westerly crossing in Stokenchurch is already a Puffin Crossing and therefore no further works proposed.

Due date

Anticipate Jan 2019

Extension of 40mph speed limit along A40, Oxford Road (towards Dog Rescue Centre) on approach to Ibstone Road junction near M40.

Aim to reduce speeds on approach to junction.

Due date

TRO Covered within 2018-19 Design Target Cost
Pending feedback from Thames Valley Police will proceed to statutory consultation.

  • Section in cutting studs upgraded to 'solar' illuminated studs
  • upgrade lining within 60mph section to 'Life Line 200' for improved night time and wet weather visibility.
  • refresh Coloured High Friction Surfacing
  • introduce Coloured High Friction Surfacing on key points (West Wycombe bend, West Wycombe Zebra, Pedestal Roundabout approaches)
  • introduce coloured surface at key locations to highlight problem junctions.

Aims to improve safety along length of route through improved lining and stud specification and also enhanced skid resistance at critical sites.

Due date

Oct - Nov 2018 with remaining work by March 2019.

Notes

This excludes works already undertaken within vicinity of Site 10 (Stokenchurch to Studley Green) and also works undertaken by CMP Team on joint resealing through Studley Green.

  • Site 1 Pedestal Roundabout - HFS and refresh
  • Site 5 Pending agreement of Speed Limit
  • Site 11 - Following Signals upgrade
  • Site 13 - Following Signals upgrade
