It makes no sense to implement this diagonal barrier measure at least until the School Street is introduced on the far eastern end of Staveley Road. The school street will reduce the rat-running from the A316 during the busiest parts of the day.Without the School Street in place rat runners (guided by SatNavs) will still drive west along Staveley Road and turn left into Park Road and right on to Lawford Rd and then try and exit on to Sutton Court Road opposite the busy junction with Grove Park Bridge (north).In the afternoon rat-runners who now travel east on Staveley Rd would find their way blocked by the diagonal barrier and will presumably learn to instead continue along Sutton Court Rd and Burlington Lane (passing the busy junction with Grove Park Bridge mentioned above).Most vehicles travelling east on Staveley Road during the rush hour have travelled south on Sutton Court Road. There are of course no measures in this scheme to prevent rat runners crossing the A4 and driving south into the area. Sorting out the A4 / Sutton Court Road junction has for many many years been dumped into the "sort-that-out later" box.  Of course once the school street is introduced on Staveley Road traffic volumes should reduce significantly and the need for the diagonal barrier will be much reduced i.e. it will serve largely as a "belt-and-braces" measure serving mainly just to inconvenience local residents and their visitors.What the main drag of Staveley Road needs (and has done for several years) as every resident knows is permanent speed enforecment cameras. When all is said and done this is a residential street. Did I mention that so far as I am aware there has been no traffic modelling to see what the impact on the local roads will be?For the record my home is on the corner of Park and Lawford Road.

Sam,It is pointless doing traffic modelling for this type of project.  Traffic modelling just gives a prediction for journey times with a certain number of vehicles going along a road and junctions of a certain design.  It doesn't predict the future by saying how may drivers will take an alternative route after changes to a road.The only way to know what drivers will actually do is actually implement it. This is the advantage of doing an experimental traffic order. If you want certainty, then the design should put in planters to close roads completely and give no other options.  If rat running along Lawford Road is an issue, then just close one end with a planter.  From the traffic measurements, only 60 people in 12 hours used it for local journeys to access Sutton Court Rd.I am keeping track of the number of times I have told you something and the number of times you ignore it.  This is the fourth time I have told you that the government are only providing funding for temporary measures hence changes that require construction will need to wait until more funding is available.  More funding won't be available if initial temporary measures don't happen.  The government is very keen to ensure this.  Speed humps and a redesign of the A4 Sutton Court Rd junction both require construction.Anyway, be careful for what you wish for with a redesign of Sutton Court Rd / A4 junction.  I haven't seen a design but in my opinion, it would mean loss of a number of car parking spaces and also the closure of Sutton Lane N, maybe at the roundabout with Barrowgate Rd.  Access to Grove Park from the eastbound A4 would then be via Hogarth roundabout.

Richard,Hounslow commissioned the traffic survey from a company called Tracsis.  It was done using a combination of ANPR cameras at the boundary roads, sensor tubes on some other roads and a video recording in one location.I asked Hounslow for the survey data and they provided it to me.  (FYI it consists of about 85 spreadsheets of total size about 100M )As I have some knowledge and experience in this area, I generated reports from the source data (using python code and the pandas data analysis library) and then loaded these into an application called Tableau Public to create visualisations of the data.So for example, the ANPR data was gathered 7am - 7pm on a weekday while the road counters were 24x7 for two weeks, so I have averaged the data from the road counters for weekdays between 7am - 7pm to allow "apples to apples" comparison with the ANPR data.I don't understand your points about alternative routes."Coming north the only alternative is to go to Chiswick Roundabout if you want to get onto the A4/M4. "Surely a driver going north on the A316,  just needs to take a left at Hogarth roundabout to get onto the A4/M4.  My point was that it is quicker (according to google maps) to take this route rather than turn into Burlington Lane - which may be shut during school pickup and drop-off times anyway depending on the school streets scheme.I don't understand your points about coming south.The objective of the measures on Hartington and Staveley is to try and make northbound drivers on the A316 stay on the A316 so they use Hogarth roundabout to get onto the A4.  If they can't use Hartington and Staveley then you certainly can't assume that every single one of them will use Burlington, given it is longer that just staying on the A316.If you look at the time profile of traffic along Hartington, there is a northbound peak in the morning but there isn't a corresponding southbound peak in the evening.  This indicates drivers are cutting through Grove Park from the A316 to A4 in the morning but they aren't using the same route coming back in the evening.  This shouldn't be a surprise given it isn't easy to cut through Grove Park from the eastbound A4.  They are most likely heading down the A4 to Hogarth roundabout and getting the A316 from there.  They really should be using the A4 and A316 in both directions.

Paul,I’m the first one to say there is uncertainty about how much traffic may be diverted (although Richard Potts claims that 100% of traffic in both directions will now use Burlington Lane makes no sense).Having looked at other schemes elsewhere I think it maybe could be said the measures favour fewer detours for residents at the expense of some uncertainty about displaced traffic. The point of doing things using an experimental traffic order being that traffic can be monitored and measures adjusted.  There could be measures that give more certainty at the expense of more detours. There is no such thing as the perfect solution, there are always trade-offs.On the point about measures elsewhere, money, resources and time are finite so you can’t expect a plan for everywhere.For example, I know that Hounslow did get commitment for money from TfL to put in measures for the Wellesley Rd area to mitigate possible displacement following closure of Wellesley and Stile Hall (this was pre-Covid so the money may need to be re-applied for). However there is no point publishing plans until there is real world experience of the impact. Will lots of traffic divert to Oxford Rd N? Dunno. Hounslow did say they would be exploring options to address traffic in the Dukes Ave area and that would need to look at Barrowgate Rd east. I don’t know if that is funded.Improvements to the SCR/A4 crossing certainly aren’t funded and will be dependent on the S Chiswick temporary measures going ahead. That will need to look at Barrowgate Rd west (my guess is that Sutton Lane N will be closed so traffic from eastbound A4 to Grove Park will no longer use Barrowgate)Every single scheme that restricts traffic attracts division and complaints and this is no different.The closure of Wellesley Rd and Stile Hall now seems to be quite widely accepted. As a resident in the area, I can tell you the shock, outrage and predictions of doom when the plans first appeared 3.5 years ago were the same as the reaction to the S Chiswick scheme now and will be the same as the next area, wherever that is.
