South Street roundabout/Twickenham Road - response from LBH

Copied and pasted below is the response I've received from LBH (following my complaint to Cllr. Mayne) regarding the South Street junction.Hopefully we'll see an improvement - although I've got even less faith in Road Safety Audits now than before !!!.Adam------------------------------Dear Mr Beamish, Councillor Mayne has asked that I respond to you directly regarding the ongoing works on Twickenham Road. I’m sorry that you’ve considered it necessary to write to express concern over the incomplete work and the delays in implementation. The past and on-going situation is far from satisfactory, but I can assure you that lessons have already been learnt and we will be reviewing our work practices ahead of the implementation of any future major schemes. In terms of completing the current Twickenham Road scheme we’ve been working with Hounslow Highways to have the works completed as soon as possible. It has been confirmed to me in the last few days that work to remove, rather than ‘black-out’, the old and existing road markings will commence on the evening of 20 January 2014 this will take 5 or 6 nights to complete as these works stretch along the complete length of Twickenham Road. The application of the new road markings will start on 21 January 2014 and this will take around 7 to 10 days, depending on the weather; again these works stretch along the complete length of Twickenham Road. The removal of the redundant traffic signs will be completed by the end of this week. I note that you’ve suggested that a ‘roundabout ahead‘ warning sign should be considered for the approaches to the South Street roundabout. One of the aims of the Twickenham Road scheme is to improve the streetscape environment by reducing street clutter and this would include the provision of extra traffic signs. There is no requirement to have ‘roundabout ahead‘ warning signs and our view is that these signs are unnecessary. The mini-roundabout signs (white on blue), whilst positioned close to roundabout as per standard practise, have sufficient forward visibility. An independent Road Safety Audit was carried out on the design prior to implementation and no concerns were raised regarding inadequate signing of the junction. I accept that the northbound approach to the South Street roundabout has been an issue. It is hoped that once the road markings are permanently removed and the new markings applied that drivers will form only one lane on this approach. We will review this just as soon as the markings at this location have been completed. You may like to know that a further independent Stage 3 Road Safety Audit will be carried on completion of the road marking and traffic sign element of the scheme. I hope that this information helpful. Should you require any further information regarding this scheme then do not hesitate to contact me directly. Yours sincerely__________________________________________________Christopher DeakinsTeam Leader - Network Management

Adam,My morning drive is more than an hour earlier than yours, so I do not suffer from any traffic, and am quite happy not to have to wait for the green light which used to be where now is the famous roundabout.As for the afternoon, my experience is that the Worton Road traffic lights are always a nightmare, the queue starting usually somewhere around the Shell petrol station. The issue you have in the northbound direction (by the sounds of it) is not the new roundabout, but the arrangements before it. But to be honest with you, there have not been much changes. This is what actually changed:1. Traffic lights were replaced with a roundabout. With the equal number of lanes roundabout is always faster than traffic lights.2. The number of lanes was reduced from two to one. There is now no dedicated line for turning right. I believe it was the only option, as extra room was given to the cycle lane, and there is simply no space there to accommodate a decent pavement, acceptable cycle lane and two lanes for cars. So this had to happen.As for the fact that there are drivers, who, as you say, “force their way in”:(a) This did not change. Under the previous arrangements, there were drivers who kept in the right lane before Worton Road, and then moved to the left lane before the traffic lights. This was (and is now) completely legal. By the way, under the previous arrangements there was traffic moving from the left lane to the right lane, in order to turn right into A3004. Such intersecting flows of traffic were not very safe and created additional congestion.(b) One may argue that “forcing the way in” is bad manners. I would disagree with this, keeping in mind that it is usually not really “forcing the way”. In fact it is good manners not to delay others, to occupy all available road space, including the right hand lane if you are going straight (yes, this is what driving instructors in fact teach), start moving early, signal well in advance if you intend to turn left, so that drivers behind you can move to the right lane and this way keep the traffic flowing.I personally sometimes end up in the right hand lane, sometimes in the left hand lane. Whenever I am in the left hand lane, I don’t have any problem with cars on the right –cars always make it from 2 lanes into one, one from each lane at a time. And there is really only one lane after Worton Road. If I’m in the right hand lane and there is a car in the lane to the left that left the junction together with me, I would slow down, let this car in, and join the lane behind it (if someone behind this first car believes this is rude, I totally disagree with it. Two lanes joining into one happens all the time, this is the way traffic system is designed, and this is how it has to operate).So generally speaking, my observation is that the arrangements are not perfect, but given the existing flow of traffic and the limited road boundaries, the arrangements are fit for purpose and are better than they used to be.

Dear Sir, I thank-you for your reply but I am bound to say that my experience of driving in the South St./Twickenham Rd. area is vastly different from the one you describe.  I was also disappointed that the problems that have been caused by the shortening of the median strip at the junction of Daws Avenue/Twickenham Rd. have been completely ignored, more drivers ARE carrying out an illegal right hand turn around/across the median strip to avoid the much worse traffic on Twickenham Rd.  The whole point of the strip being lengthened in the first place was exactly because of this problem which also caused quite a few fairly serious accidents and several more near misses, yet this was entirely discounted because of safety of cyclists apparently. Why do you never learn from bitter experience? There are problems still with bad congestion at the junctions of Twickenham Rd. Mogden Lane and also Twickenham Rd. /Worton Rd. Drivers are still forming two lanes from Worton Rd. junction encroaching on the cycle lane, cross hatching on the road from the lights indicating that it is ONE lane up to the roundabout really are needed. I have no knowledge of when your traffic consultants actually carried out their survey, but I find it increasingly frustrating that you continue to ignore local residents who use this area more frequently.  I am aware that Hounslow Highways were supposed to remove the erroneous signs but they were supposed to have done that by the end of January and didn't, how long can something quite simple take? I have to say I have little faith in your 'road safety auditors' as that will be dependent on the time of the audit, and I would far rather believe the evidence of my own eyes and experience, which as far as I can see counts for absolutely nothing. After all I only live here, and no-one I know would agree that journey times are shorter, in fact they are far, far worse, the fact that Twickenham Rd. is the main route between the A316/M3 and the A4/M4 seems to be entirely overlooked as does the location of several schools right near the South St. junction, which in themselves create a lot of traffic at rush hours, not to mention a major hospital being located on Twickenham Rd. Unless your auditors can spend a fair amount of time in the area over several days they won't have a clue as to the real situation  - pitching up mid morning after the busiest time might give you the impression that all is well, not so. I am bitterly disappointed at the whole way this exercise has been carried out, what may look so good on paper does take on a different look in practice. I am sorry, I simply cannot agree that this scheme has made any improvements to the local area as regards traffic flow or pedestrian and cyclists safety. I look forward to some attention to the matter of the median strip problems. Yours sincerely, Vanessa Smith

Cc: Jennifer Morgan, Councillor Sue Sampson      Dear Ms Smith, I refer to your correspondence with Councillor Mayne regarding Twickenham Road and South Street junction. A report by traffic management consultants based on traffic movements following installation of a temporary mini roundabout to replicate the layout proposed demonstrated that whilst at times some of the queue lengths did increase the overall journey times on the section of Twickenham Road between Isleworth Recreation Centre and Mandeville Road had reduced; indicating that queues were moving rather than static. Southbound journey times had reduced by 25-37% and northbound journey times had reduced by 15-23%. We do not envisage commissioning any further reports at this time as visual site inspections appear to confirm peak time results as indicated above and also confirm off peak traffic movements have improved considerably. With regards to erroneous signs, the site was inspected in Jan 2014 with representatives of Hounslow Highways and the Principle Contractor to identify any outstanding work and determine areas of the scheme that require rectification. Hounslow Highways are currently arranging for the work to be completed. Following completion of any outstanding work, we will commission a stage 3 road safety audit to be carried out on the scheme, this will be undertaken by independent road safety auditors in conjunction with representatives of the Metropolitan Police. I anticipate this to be completed during spring this year. Regards Jaspal KharaySenior EngineerTraffic Management & Road Safety
