- The Hanworth roundabout has been hamburgerized meaning that the peak-only traffic lights are now 24/7. I'm not sure this was necessary, as (other than peak time) I've never had to queue for long here. And at 1am, predictably this meant that I sat at a red light for ages, with no other cars in sight.
- But the big shock... the Nine Mile Ride roundabout has been replaced with a flat, traffic light controlled junction. Yes, Bracknell has lost a roundabout. Again, I do not understand this, as the roundabout worked (even at peak time).

A3095: Bracknell has *lost* a roundabout
From the SABRE Wiki: A3095 :
The A3095 is a short semi-rural A-road providing a route to Bracknell from certain parts of eastern Berkshire. As may be expected from a road passing through a New Town, its route has changed considerably over the years and it is very difficult to determine its former route.
The road now starts at a TOTSO on the A321 on the edge of Sandhurst. This section of the road acts simultaneously as a bypass for parts of Sandhurst and the neighbouring town of Crowthorne. After

It's cheaper. It's harder than ever to find a quality scheme at the moment. Like pretty much all 'pinch point' signalisations etc, they have ignored decades of flow control technology development in favour of cheapness and sequences that can be programmed in a 6th Form level software package.Micro The Maniac wrote: ↑Wed Jan 05, 2022 19:09
Given the work that has been undertaken, why oh why oh why were the traffic lights not fitted with flow control. Why was it necessary for the only car in sight to be sat at two sets of red lights, while they rotated through their respective sequences (including the slots for the non-existent pedestrians to cross)?

My only issue with the Hanworth roundabout is that it seems to have shifted the queues on Ringmead onto the Hanworth Road.

Does this means that the signals are on a timed sequence, and not activated by detector loops? I had no idea that such controllers are still used!DB617 wrote: ↑Thu Jan 06, 2022 23:08It's cheaper.

Re: A3095: Bracknell has *lost* a roundabout
M5 Junction 2 certainly seems that way. The only way to emerge is to jump the red light as you'll be waiting for an eternity otherwise and this happens a lot so just be careful plod isn't around when doing this. The problem with these so-called pinch point schemes is they attempt to solve peak hour congestion but worsen things at night. The majority of them should have part time signals.Peter Freeman wrote: ↑Sun Jan 09, 2022 10:42Does this means that the signals are on a timed sequence, and not activated by detector loops?

Big and complex.
Re: A3095: Bracknell has *lost* a roundabout
There's a set of lights on the B656 (formerly the A505) about a mile from where I live that I am sure has no detector loops. You are often stopped here on the mainline when there is nothing going in or out of the turning that accesses an industrial estate and a retail park.Peter Freeman wrote: ↑Sun Jan 09, 2022 10:42Does this means that the signals are on a timed sequence, and not activated by detector loops?

Re: A3095: Bracknell has *lost* a roundabout
IME most of the sets are fitted with plenty of detector loops etc, but they almost seem to act like pedestrian beg buttons, just telling the set to give a green aspect to that side on the next go around. Perhaps the detection equipment brings the cycle forward by a few seconds, but not even close to enough at off peak times. It's theoretically possible to give a green to every vehicle that approaches solo (with no conflicts from other arms) but it seems the programming legwork isn't being done. Suspect the programming people are being offered very minimal payment.

Re: A3095: Bracknell has *lost* a roundabout
Not the programming people, but the managers who write the specs. I have had many years of experience of poor specs and those responsible for writing the specs not willing to upgrade them.DB617 wrote: ↑Sun Jan 09, 2022 15:06IME most of the sets are fitted with plenty of detector loops etc, but they almost seem to act like pedestrian beg buttons, just telling the set to give a green aspect to that side on the next go around.

As someone born and raised in Stevenage, I'm not sure if Bracknell can call itself a New Town anymore.
