Respondents requested that we install a signalised pedestrian crossing across Honor Oak. Whilst praising the adjustments proposed, concerns were still given that fast vehicle movement and lack of sight lines meant that the crossing was still dangerous.
We have investigated installing a signalised crossing across Honor Oak Road. However doing so would mean traffic at the junction would need to completely stop to allow pedestrians to cross the width of Honor Oak Road. This would create significant delays & additional queuing on what is already a very busy junction, particularly at peak times of day. In order to limit the impacts of this the signal timings would need amending and consequently it is very likely pedestrians would need to wait for a significant amount of time before receiving a green man signal. At other junctions where this has happened it has been observed pedestrians rarely wait for the green man to appear and instead cross in between times.

We are however widening the pedestrian refuge island on Honor Oak Road to 2.4 metres – double the existing width. This should provide a more comfortable place to stand whilst waiting to cross the second half of the road. Additionally the carriageway is being narrowed at the junction. Vehicles will therefore need to slow down in order to turn into Honor Oak Road, providing greater visibility between pedestrians and vehicular traffic.

There were requests to install a yellow box at the junction to stop vehicles blocking the exit onto A205 from Honor Oak Road.
There are strict rules that must be met in order to install a yellow box on the carriageway. For these reasons it is unfortunately not possible to install a yellow box on the westbound carriageway of London Road. However we are proposing to install a ‘keep clear’ marking here to address concerns raised. This will be implemented in advance of other works at the junction.
