A41 Bicester Road Primary Public Transport Corridor

We are proposing highway improvements along the A41 Bicester Road in Aylesbury. The section of road affected is between Sir Henry Lee Crescent at Aylesbury Vale Parkway Railway Station and Rabans Lane junction.

The aim is to create a Primary Public Transport Corridor (PPTC) that improves traffic flow for public transport users and general traffic too. PPTC’s are areas that have more than one transport option, such as highways, railways or buses.

The changes are due to be completed in 2022.

Current progress

The detailed design for the scheme is complete and construction works will begin along the A41 Bicester Road from Tuesday 15 June. These works involve the installation of new ducting along the A41 between the Rabans Lane junction and the Paradise Orchard / Sir Henry Lee Crescent junction, in preparation for the major works which are programmed to commence at the end of July / beginning of August. The ducts are required to enable new communications equipment (CCTV, ANPR cameras and Variable Message Signs) to be installed and to link existing traffic signals with new signals at the Jackson Road / Dickens Way junction. These works will take approximately 5 weeks to complete. The advance works will take place on the following roads:

  • A41 Bicester Road
  • Jackson Road
  • Dickens Way

In order to reduce disruption as much as possible working hours will be 9am to 4pm on A41 Bicester Road and 9am to 5pm on Jackson Road and Dickens Way. The majority of the work will not impact the carriageway as it can be completed on the footways and verges, with pedestrian diversions where required. All residents will be able to gain access to their properties as usual during the works, but delays may be encountered at peak times.

Further updates will be issued prior to the main works commencing in late July / early August.

 

Consultation

The A41 Bicester Road PPTC consultation began on 18 January 2021 and ended on 14 February 2021. The project team hosted the consultation through the project webpage and a separate A41 Bicester Road PPTC consultation page on Your Voice Bucks. The project team additionally hosted a live Questions and Answers (Q&As) session during the evening of 28 January 2021. Approximately 25 individual attendees joined the live event. Approximately 6000 leaflets were distributed to nearby properties to inform them about the consultation as well as social and mainstream media.

Results of the consultation can be found in our Interim Report for the Consultation [PDF | 2.4MB]To request an accessible format please email equalities@buckinghamshire.gov.uk.

The project team have identified common queries, comments, and issues that were raised during the consultation process. These are grouped into themes and responses are set out within our Consultation Response Document [PDF | 5.48MB].

Objectives

The A41 Bicester Road corridor is an important strategic transport route linking Aylesbury town centre with Aylesbury Vale Parkway Railway Station. The high volume of traffic using this route daily cause’s regular congestion, particularly at peak travel times.

As part of making the A41 Bicester Road a Primary Public Transport Corridor, the project aims to:

  • to reduce congestion on the A41 between the western boundary of the Berryfields development and the Bicester Road/Gatehouse Road roundabout in Aylesbury
  • to reduce journey times and improve journey time reliability for all road users along the A41
  • to improve bus service information along the A41 for people to better plan their journeys

 

Proposed improvement measures

The right turn lane from A41 Bicester Road out of town towards Paradise Orchard will be extended to allow more space for vehicles to wait in the right-turn lane, so other traffic can pass straight through the junction along the A41 with reduced delay.

Traffic signals will be optimised to allow more vehicles to turn right into Paradise Orchard, along with giving buses preference within the signal optimisation.

The existing eastbound bus lane will be relocated to start after the River Thame road bridge and end shortly before the Jackson Road/Dickens Way junction. This will reduce delays for buses approaching the junction.

The eastbound merge lane will be extended along the A41 from the Paradise Orchard junction to add capacity to the corridor.

Installation of new informal pedestrian crossing opposite Haydon Hill park entrance.

The existing roundabout will be replaced with a signal-controlled junction. The traffic signals will adapt to traffic conditions and be linked with the Paradise Orchard/Sir Henry Lee Crescent junction to better manage congestion and delays.

The approaches to the junction will be widened and lengthened increasing the capacity of the junction.

Traffic signals will be optimised giving buses preference within the signal optimisation.

To the East of the junction, there will be a new signalised puffin crossing across the A41. There will also be a new Toucan crossing on the Jackson Road arm, making it easier for pedestrians and cyclists to cross the road.

There will be a new pedestrian island on the Dickens Way arm of the junction to make it easier for pedestrians to cross this arm of the junction.

There will be an extra eastbound lane (2 in total) between the Jackson Road / Dickens Way junction and the Rabans Lane junction, increasing network capacity and helping reduce journey times.

SCOOT (Split Cycle and Offset Optimisation Technique)

SCOOT systems and other traffic signal technology are used to link the proposed traffic signals together and improve traffic flow. SCOOT allows traffic signals to work more efficiently by assessing and adapting to real traffic conditions. Traffic that is approaching signals from different directions are continuously detected using loops installed in the road. The SCOOT system adjusts the duration of the green light signal to best manage traffic and minimise delays. Vehicle movement is transmitted from the loop to the signal control cabinet.

Using SCOOT has substantial benefits in reducing journey times, delays, fuel consumption and vehicle emissions. It is particularly effective in places such as the A41 Bicester Road where traffic volume changes throughout the day.

We propose to use SCOOT at the Jackson Road/Dickens Way junction and the Paradise Orchard/Henry Lee Crescent junction. These junctions can then operate efficiently together and link with the Pegasus crossing opposite Haydon Hill Park.

Automatic Number Plate Recognition (ANPR)

We plan to install ANPR cameras at the Paradise Orchard/Sir Henry Lee Crescent junction and Rabans Lane junction. This will allow us to measure journey times between the two improved junctions. The cameras can also be monitored by the Police.

Variable message sign (VMS)

We plan to install a new westbound VMS between the Jackson Road/Dickens Way junction and the Paradise Orchard/Sir Henry Lee Crescent junction to provide real-time information to drivers.

Closed-circuit television (CCTV)

We plan to install 3 CCTV cameras at all the junctions on this stretch of the A41 so we can monitor traffic flow along the route. Monitoring will mean we can alter signal timings where appropriate. The cameras can also be monitored by the police.

Bus priority

We plan to introduce ‘bus detection” on some buses. This system recognises when a bus is waiting at a junction and looks to give that arm of the junction preference. This allows the bus to progress, reducing journey times for public transport users.

The diagram below shows how all the software will operate along the route.

Impacts on side roads

With such high traffic levels along this stretch of the A41, it's essential to focus improvements on the corridor itself.

However, we realise improving journey times along the route could negatively affect the time it takes to exit side roads onto the A41. So, along with increasing capacity at the junction, we propose to set the new traffic signals at the Jackson Road/Dickens Way junction to account for that and allow regular side road traffic-flow.

If all our proposed improvement measures are put in place, we predict that those exiting the following side roads will see very little change in their journey times:

  • Paradise Orchard
  • Meadowcroft Road
  • Gatehouse Road
  • Griffin Lane

We also predict there will be reduced waiting times for those exiting the following side roads, on average:

  • Dickens Way - 14 seconds at afternoon peak
  • Rabans Lane – 15 seconds at morning peak, 57 seconds at afternoon peak

However, we predict there will be increased waiting times for those exiting the following side roads, on average:

  • Jackson Road - 51 seconds at morning peak, 37 seconds at afternoon peak
  • Dickens Way - 29 seconds at morning peak

 

Journey time reliability predictions

As well as improving journey times, we aim to improve journey time reliability with these improvements. This means that journey times should be more consistent and predictable, allowing people to plan journeys with more certainty.

Below we have predicted the journey time reliability reductions following proposed improvements. The improvement in reliability is shown as a percentage and explain how much more reliable their journey times should be once the improvement works have been completed. For these, we used the distance between Aylesbury Vale Parkway Rail Station junction and Gatehouse roundabout.

Eastbound journey (into town) during morning peak travel (7:30am to 8:30am)

We predict the average journey time will reduce by 1 minute 14 seconds with reliability improving by 24%.

Eastbound journey (into town) during afternoon peak travel (5pm to 6pm)

We predict the average journey time will reduce by 48 seconds with reliability improving by 58%.

Westbound journey (out of town) during morning peak travel (7:30am to 8:30am)

We predict the average journey time will reduce by 1 minute with reliability improving by 55%.

Westbound (out of town) during afternoon peak travel (5pm to 6pm)

We predict the average journey time will reduce by more than 2 minutes with reliability improving by 84%.

 

Funding

Buckinghamshire Council has a budget of approximately £3.5m to spend on the project. This was mostly secured as part of the s106 funding from the Berryfields development.

 

Road Safety Audit

The Rabans Lane junction is not proposed to be signalised,  therefore the comments on sections 3.1.1, 3.1.2, 3.1.3 & 3.1.4 are no longer applicable.
