C9 was fully upgraded in January 2023 so it is entirely appropriate to compare casualty figures in 2023 and subsequent years to the casualties prior to this.As I mentioned, there is vanishingly small probability that reduced cyclist casualties since C9 was complete is just 'luck'.  Additionally, it isn't just cyclist casualties are down, *all* road user casualties along CHR are at the lowest level for at least 15 years.  This is consistent with many other places where cycle lanes have been implemented - it improves the safety for other road users because it reduces the exposure to by far the biggest danger which is motor vehicles.You aren't correct that prior to C9 the biggest risk at Dukes Ave was from right turning vehicles.  As I have mentioned, 70% of vehicles turning from CHR into Dukes were turning left so this was the biggest risk and contributed to the most collisions.Another Francis Rowe "appears to me" is completely wrong if you think C9 on CHR is busier than the stretch out to King Street.  Actual counts in 2025 showed that C9 between Weltje and Rivercourt had 19% more cyclists than C9 at the junction of CHR/Thornton Avenue.Given your track record of your opinions being wrong, your 'hazard a guess' of the number of people going through red lights isn't even worth commenting on.  If you actually went there for several hours at peak times and recorded numbers using a pen and paper or a phone app then I might believe you but of course you won't.

"If you believe it is 'dumb luck' there haven't been more casualties at Dukes Ave, it is possible to calculate the probability of the 2023 and 2024 casualty figures along CHR occurring by chance based upon the previous 15 years of data"Not really. The current configuration has only been in place since the introduction of C9. The principle concern would be against flow cyclists being hit by vehicles turning right into  Dukes Avenue."Before C9 was implemented at Dukes Ave and at Weltje now, it isn't as if the people being injured were risking an illegal manoeuvre, they were just cycling along and were hit by the driver of a car who didn't look properly while turning into a side road"While I accept that the most obvious explanation for a collision at one of the junctions with cycleway 9 is a lack of care by the driver of a motor vehicle, without the full report we can't automatically conclude this was the case every time. For instance I did witness one minor collision on this stretch in which the vehicle was stationary across the cycleway and was hit by a bike whose rider simply hadn't noticed it.Of the seven serious injuries that are recorded here over the last couple of years only four involved a car. You might expect the ratio for slight injuries to be even lower."So even if some people go through red lights, this will still be a lot safer than a junction with large numbers of uncontrolled vehicle movements where lots of people are cycling."I'm going to hazard a guess at a third ignoring lights at Dukes Avenue so we are talking large numbers here. Also, the central section of Cycleway 9 in Chiswick appears to me far  busier than the stretch out to King Street. While there are probably more cyclists legitimately crossing the Weltje Road junction than those that ignore the lights at Dukes Avenue - the difference may not be that big.

Some comments on this Francis.- I think it is a mistake to ignore slight collisions.  The difference between slight and serious may only be chance and the number of slight collisions is a 'canary' showing issues at a location.- FYI the location of 'dots' showing collisions on maps like TfL dashboard won't be accurate to the metre, probably more like +/- 10m.  The full collision report has more detail on the movements of people/vehicles involved in the collision but this isn't available to the public.- "would closing access on Weltje Road transfer risk to Dukes Avenue?" Highly unlikely. Firstly, from surveys done in 2019, the majority of vehicles using Weltje were coming from the east, not west.  I will speculate this may be traffic coming into London on the A40 then coming off at Old Oak Rd, then Askew Rd, Paddenswick Rd, Dalling Rd, right onto King St, left onto Weltje for the A4 because this saves queuing at the gyratory. Rather than driving away from the gyratory, these drivers can suck it up and use the gyratory. Secondly, you refer to "transfer risk" but the risk at a junction with no controls over vehicles crossing the cycle lane simply isn't the same as a signal controlled junction.  It is nowhere near the same.  An argument of 'it is a bad idea to have more traffic using a junction because people jumping red lights might be in collisions' will not be one considered by highway authorities.- The changes will be implemented using an Experimental Traffic Order (not an Emergency Traffic Order) which can be in place for up to 18 months before a decision to remove or make permanent.  This was done for Rivercourt and the change became permanent in March.  It is quite right to implement the change using an Experimental traffic order because it is impossible to predict how traffic will react to a change over a wider area and in the grander scheme of things, the impacted traffic is really quite small.  About ~1500 vehicles coming from the west, about ~1200 coming from the west.  We are seeing the local Conservatives and some locals predicting doom if the changes are made but they always do this and they are always wrong.

I had a look at the collision data in detail and can confirm what Michael says is not inaccurate.There have been three collisions involving cyclists resulting in serious injury in the vicinity Weltje Road recorded in 2024 and 2025. One of these, that took place on 05/02/2024 is shown as being a short distance away from the junction with King Street.During the same period there were another four collisions resulting in serious injury along the stretch of Cycleway 9 running between the commercial centres of Hammersmith and Fulham. The Weltje Road junction has been the scene of more serious collisions but there have been two rather than one seen at other junctions.Even if you were to include the third collision slightly further away you would be hard pressed to conclude firmly that this proved that Weltje Road was more dangerous based on the last two years. However, given that it had a spike in serious collisions after the introduction of the cycleway – there is a long term pattern here. Perplexingly these early collisions no longer appear in the data – perhaps they were downgraded following investigation.At the same time, it is also accurate to say that the centre of Chiswick has had remarkably few cyclist injuries in recent years including at the Dukes Avenue junction. While I have observed close calls at this junction on multiple occasions, people appear to have got lucky or perhaps drivers are adjusting behaviour to account for people doing something silly.The question is, would closing access on Weltje Road transfer risk to Dukes Avenue? The data that we have suggests that the former is the more inherently risky but is that just because of the number of vehicle crossings rather than anything inherent in design. It would be wrong to be complacent about the extra traffic generated by the change – in the age of Sat Nav the quickest rather than the shortest route will be chosen and, even for vehicles approaching from the north, Dukes Avenue will be the selected route rather than Chiswick Lane or Sutton Court Road.I don’t know the answer but I am pretty confident that neither LBHF or LBH do either. By using an emergency order, the need to consider these questions has been bypassed and it is an essentially a trial the success or failure of which will be determined by the number of cyclists seriously hurt at the Dukes Avenue junction. Personally I think there haven’t been injuries here due to dumb luck but the chances are about to rise significantly.Collision ID 1240494331 summary: On 05/02/2024 there was a serious collision at 10:40 at On King Street, Near The Junction With Weltje Road ...

Francis,This petition was organised by a Conservative activist called Tim Janman  I am suspicious of the claims that he has signatures from 44 residents of Weltje Rd as that does not align with the level of complaints about traffic that I have heard LBHF are receiving from Weltje Rd residents. Perhaps he has managed to find the residents who altruistically want their street to be used as a through route to the A4 and believe this enhances the ambience and desirability of the street.As usual, "the best of your knowledge" isn't very knowledgeable as there were 3 serious cyclist casualties in 2023 and 2024.  In contrast there were 0 along the 1.2km of C9 on CHR, which has 12 junctions.  There were more collisions of all types at Weltje than all of C9 along CHR. 2025 figures should be released officially in September.Significantly more cyclist collisions happen with vehicles entering a side road from a main road than a side road to a main road.  When entering a side road, drivers frequently swing into the turn at speed while when entering a main road, they are usually stationary or low speed.  As Weltje was a route to the A4, this made the number and severity of collisions even worse.What is the "belated improved junction design" at Weltje?  There have been no changes to the junction there.  The changes to offset the cycle lane away from the junction were done at Rivercourt, not Weltje.I can only speculate about why LBHF have taken so long to do something.  Perhaps they didn't want to do anything because they were scared it would annoy drivers but the number of casualties made it untenable.  Perhaps they were emboldened by the recent election results as Labour did well in LBHF compared to most other areas and the Conservative car-centred policies got nowhere in the polls.With the restrictions at Weltje, all other junctions along C9 will either be signal controlled or the volume of traffic crossing the cycle lane will be within guidance. Dukes Ave will be the only route to the A4 which isn't a street designated on the borough principle road network.

Maria, if you live on Weltje Road and supported this scheme, you would have every right to condemn people who didn't live there and opposed it. However, most of your neighbours appear not to agree with the plan presumably on the basis that the access restrictions will cause more hassle than the reduction in the number of vehicles going down their road.The timing of this seems odd. After the initial carnage for cyclists at the Weltje Road junction when Cycleway 9 was introduced, to the best of my knowledge there have been no serious injuries at this junction. You can credit that to the belated improved junction design or cyclists and motorist being more aware of the risks but, whatever the reason, the reduction in injuries undermines the safety argument for these changes.Also thought needs to be given to where all these vehicles will now be crossing the cycleway. The main transfer will be to Chiswick Lane and Dukes Avenue junction. Michael has argued in the past that signalisation makes these safer and I would agree in the case of Chiswick Lane which, although disregarding of red lights is endemic, the sight lines are much better. Dukes Avenue on the other hand is clearly highly dangerous - ten minutes observation would make this apparent to anyone. I've not seen a report of a serious accident here but over the last couple of years I've seen several close shaves here. Three times while I have been waiting at the lights on my bike going west an eastbound cyclist has continued on and had to come to an abrupt halt due to an east bound car turning left. Collisions were avoided by centimetres not metres. I'm not sure directing more vehicles to this junction is a good idea.
