Traffic lights by Forest Hill station

I think there is something wrong (again) with the timing of these lights. The green phase for traffic turning out of Dartmouth Road on to the South Circular was only fifteen seconds long this evening, producing a very tedious queue on Dartmouth Road northbound. Does anyone happen to know how best to report this?

Please can others call TFL and ask them to do something. I’ve called about 10 times and still they’re not right. They have logged it as both a possible hardware and phasing fault. One tfl guy said all the phasing of the lights across the junction are out and it would be a big job - but that was weeks ago.


Was called by TFL yesterday to say that it was a fault with the traffic sensor which has now been rectified and asked if we have noticed a difference. I said I’d have a look and get back to them.


Thank you!

Your numerous calls paid off & down to you all is back to normal now :slight_smile:


Excellent. Thanks Pauline. Tfl were very slow to fix this time.

It seems they are not working properly again. Traffic along London Road terrible - has been for weeks. Seems to me the possible culprit is the pedestrian crossing light from the London Road corner going across towards Dartmouth Road which is staying on green for far longer than previously. The result is less time for vehicles to turn left towards Catford. I have reported to TfL, but it takes 10 days to get a reply. Anyone else worth contacting (local councillor etc?)

The northbound traffic on Dartmouth Road also seems a lot slower in the mornings than usual. I had thought it might be some sort of knock-on from the (still continuing?) roadworks at the junction of Sydenham Hill and Sydenham Rise, but perhaps it too is in fact caused by a problem with the lights by the station.

I’d tended to assume that TfL routinely monitor traffic flows and take action automatically if anything needs sorting. Am I being naive?⁶

I had a friend who worked at TfL for a while.

He said they monitor and model most of the traffic systems and use that to come up with changes to improve the traffic flow. Proposed changes are evaluated against the models with previous captured data, and when things look good the changes start to be implemented working from the edge of London and moving gradually inwards. Predictions from the model are verified as they go, stopping and rolling back if things don’t match up.

I’m not sure how long it takes them to roll out a set of changes, but I got the impression it was a on scale of weeks to fully implement changes.

Perhaps this is a case of it going wrong, or just good old human error!

Yes We’ve noticed since the phasing has changed at junction of London Rd and Dartmouth road the traffic has been horrendous!

Didn’t seem quite so bad yesterday?

There are also roadworks up near the Horniman where one of the lanes is shutdown - this is causing traffic to back up all down the South Circ past FH station…

From TfL today.
