I've reviewed all the data reports given for the Ealing LTNs and Tom Pike is correct to say that the traffic data shows significant reductions for most of them both within the LTN and on the boundary roads. This has clearly come as some surprise to the respondents to the consultation who have cited extra congestion as one of the main reasons for their overwhelming opposition.However, the basis of the data for traffic reduction is unclear. The source is quoted as 'Floow' but no dates are given for when the comparisons are made and just one road is used as a control which is within the affected areas. The presentation of this material is sloppy and appears to be unsound.If you scroll down further data from iBus is provided by TfL what this does show is that in most cases there have been rises in bus travel times on bus routes adjacent to the LTNs in the most recent quarter (March to June 2021) when compared to the same quarter pre-pandemic in 2019. In many cases these are quite significant.  It is hard to square the data from 'Floow' with this rigorously prepared and authoritatively sourced information which suggest very strongly there has been a significant increase in congestion in roads in the area.The issue for Ealing from here is that if they show the 'Floow' data to the government Mr Gilligan will quite rightly ask why on earth they are not persisting with these schemes as the problem is quite clearly that the people who live in the LTNs are deluded idiots incapable of recognising the benefits that have been provided to them by failing to observe that traffic has disappeared from local roads that they walk down every day. On the other hand if they show him the iBus data he may feel it is not a good plan to make public transport less viable if your aim is to discourage car use.

“However, the basis of the data for traffic reduction is unclear. The source is quoted as 'Floow' but no dates are given for when the comparisons are made and just one road is used as a control which is within the affected areas. The presentation of this material is sloppy and appears to be unsound.”The traffic data is stated as being collected between January and March 2021 and the matched week to the control data is given. The control, Argyle Road, is stated as having been selected because it was well away from all the LTNs. You can’t claim the analysis is “sloppy and unsound” when you have simply overlooked the information you claim is missing. “If you scroll down further data from iBus is provided by TfL what this does show is that in most cases there have been rises in bus travel times on bus routes adjacent to the LTNs in the most recent quarter (March to June 2021) when compared to the same quarter pre-pandemic in 2019.”I count 17 cases of decreased bus delays, 18 of increased delays and 3 of no change. The differences were all less than a minute. On that basis it’s difficult to claim there was any significant overall change in bus delays when it’s on average a fraction of a minute.The buses run along the boundary roads, not through the LTN’s that on the whole saw large decreases in traffic. There is therefore no contradiction between there being no significant change in bus delays and a large decrease in traffic counts within the LTNs.

The traffic data does look very suspect and, like Jeremy, I couldn't find any indication of what the base comparison was for the figures.If you take one of the LTNs in West Ealing the Floow data shows all roads within the LTN experiencing a decline in traffic with one down by 97% This is obviously one on which a barrier has been placed but necessarily other roads must have experienced increased traffic as residents circle round to get home but this appears not to be taking place.The road which saw a 97% fall in vehicles is Loveday Road which is about a quarter of a mile long and all residential. The report claims that this has seen traffic fall from 266 vehicles an hour to just 7. The number of delivery vehicles in my road which is much shorter exceeds 7 throughout the day in about 15 minutes so it is impossible to believe the number given in the report.The use of Argyle Road as a control is clearly flawed - it is the B452 and is adjacent to LTNs and an extension of Northfield Avenue which is a distributor road for more than one of the LTNs.As far as I can see Floow is a subsidiary of the Direct Line group. If this information has been collected by a private company commissioned by the council it is hard to discount that they have provided conclusions which were pre-determined.Although I haven't looked at the bus data in detail a scan of several of the main schemes did seem to indicate that there had been significant increases in bus travel times more often than not. However, even if you are prepared to endorse Tom's contention that the impact on bus travel times is broadly neutral this does suggest the schemes are failing in this regard. Bus passenger levels for the latest quarter would be at around 60% of those for the comparison quarter pre-pandemic. This should mean that the service runs more quickly and reliably so even if you can find an interpretation of the figures that indicates bus travel times are overall unchanged, they should have fallen so the LTNs appear to be generating more traffic.
