Headington roundabout multiple safety problems

Serious issues in use include: - Major design issue. Traffic to Barton from A4142 eastern bypass. Dangerous and unsafe layout as drivers going to Barton direction risk getting sideswiped by cars going over roundabout heading west.

- Enforcement issue. On approach from A4142 eastern bypass, drivers wanting to turn right and head for London but unwilling to wait in right hand lane routinely misuse roundabout by using the middle lane to turn right risking collision with other cars in correct lanes eg cars traveling straight over and heading to North Oxford.

  • This is something that I see daily and no amount of signs or road markings will stop it from happening! Why oh why did someone think that it would be a good idea to have a left lane that turns right on the biggest roundabout in the area? Why do we need two lanes going into a village but only one onto the main A40 to the north of Oxford. If someone can explain the logic and safety of this issue then I will stop campaigning for it to be changed!

  • Thank you for your report - during the planning application for Barton Park, transport modelling was undertaken to show the operation of Headington Roundabout before and after the Barton Park development is fully occupied. This showed that without the mitigation of changing the road markings the development would have a detrimental impact on the operation of the roundabout and the local highway network. There was also a high number of collisions on the roundabout in the 4 years leading up to the planning application.

    The changes to the road markings were made to better utilise the lanes to improve movement towards London and into Barton. This has significantly helped the length of the queue on the A4142 Eastern Bypass for cars turning onto the A40 East towards London. In regard to movement into Barton, at this stage whilst the Barton Park development is still under construction it is not known the full extent of the impact the mitigation will have. It is not considered sensible to redo the markings when the reason they were changed has not yet been tested and therefore it is recommended from a planning perspective that the changes remain in place until the Barton Park development is fully occupied.

    The changes to the road markings were completed at the end of October 2017. In September 2018 two lane board traffic signs were erected on the A4142 Eastern Bypass approach to the roundabout to improve lane discipline. Amendments to the destinations on these lane boards were made in June 2019 in an attempt to further improve the situation.

    Interrogating the OCC / Thames Valley Police personal injury collision database there were five slight injury collisions on the west side of Headington Roundabout between when the road markings were changed in October 2017 and the end of December 2019 (our most recent data). During a similar 26 month period leading up to the road markings being changed there were one serious and seven slight injury collisions in the same area of the roundabout.

    Notwithstanding the above, the council is aware of the on-going concerns to which you have referred and as such we continue to monitor the site. Further reviews of the roundabout operation will be undertaken as necessary.
