You bring up another issue, past data should also be accessible, so residents can see the association of change with council policy, school holidays and seasonal effects. It’s all very poor - if you consider how much easier it is to collect and collate data now, the previous detailed report I added to the thread puts newer Council bodies to shame.

The zebra crossing make very little impact as cars have to stop or slow approaching the round about, but yes the temporary light have caused lots of issues as it was set up as a four way stop and originally drivers didn’t realise so thought lights were not working, so we’re going through red lights. The timing was also not quite right. I spoke to one of them walking up to LL when they were day 1 of digging another whole. There is very little flexibility in the system now, so the ambulance coming down that day had a big delay as couldn’t use Melbourne. I do wonder if an open end with cameras would be helpful for emergency access, but that’s for the forum tread really.

It’s important we know the amount of traffic and especially start-stop traffic on our local roads in East Dulwich as electric vehicles still pose a risk to health as they do not necessarily emit less PM2. 5 than internal combustion engine cars. (Although lightweight EVs emit an estimated 11-13% less PM2) As has already been said - there are no excuses, we have a right to have accessibility to this data. write to your local councillor demanding visibility and accountability

Again, if people want to discuss national strategy do this in the Lounge, this thread is about East Dulwich Street space Dashboard and the failure to update this information for over 6 months. Again I cannot believe that anyone living in East Dulwich is not interested in the levels of traffic and pollution on their doorstep. I suggest everyone contacts their local Councillor and asks for transparent and up to date information, at the very least on a quarterly basis.

and .....an idling engine burns fuel less efficiently and can produce up to twice the emissions of a car that is moving. It pumps out unnecessary sulphur dioxide, particulate matter and nitrogen oxide into the atmosphere, but of course stop-start technology and electric 'engines' are reducing this. What does cause more pollution is vehicle miles traveled being a strong correlate, but that might be for the 'you know what' in the lounge thread.

If you want to discuss carbon dioxide emissions (yes globally important) go to the lounge. This is about East Dulwich Dashboard - traffic and pollutants locally and as CO2 not measured locally - then not relevant. (happy to discuss CO2 in the lounge - the main human activity that emits CO2 is the combustion of fossil fuels (coal, natural gas, and oil) for energy and transportation and Just Stop Oil have a point....). But again this is a thread asking for transparency and publication of data that was promised by the Council - what is the argument against?

Don’t really understand why carbon dioxide is being mentioned? Nitrogen dioxide NO2 (excuse the lack of subscript) is a very different gas, highly reactive and causes damage to the respiratory tract. It’s a major trigger for asthma and implicated along with PM in the death of Ella Kissi-Debrah in a landmark coroner’s report. It is important that we know the levels of Nitrous gases and particulates in our local environment in East Dulwich. I am sure that any asthmatic, COPD sufferer or a parent/guardian responsible for a child’s health would like access to this local data. Is anyone actually arguing against residents having access to this information?

In itself it is a very informative site, but none of these monitors are in East Dulwich, the nearest is the South Circular, that is weirdly not included in the dashboard if memory serves me right, So in keeping with this forum, the data from monitors in East Dulwich are relevant to residents rather than sites on The Old Kent Rd and Tower Bridge Rd. Apparently there are pollution monitors in East Dulwich, but access to data isn’t clear. I’m asking if our Council can publish data for East Dulwich specifically. It is just NO2 tubes... the last time data was published....wait for it ...was.... up to 1992, which is quite shameful. https://www.southwark.gov.uk/environment/air-quality/air-quality-monitoring-data The air pollution data for Southwark for the period 1950 to 1992 can be found in the Air Pollution in Southwark 1950 to 1992 report, which includes the following chapters: Chapter 1 Introduction (PDF, 2.8mb) Chapter 2 Sulphur Dioxide (PDF, 1.7mb) Chapter 3 Nitrogen Dioxide (PDF, 1.7mb) Chapter 4 Ozone (PDF, 740kb) Chapter 5 Lead (PDF, 1.1mb) Chapter 6 Carbon Monoxide (PDF, 909kb) Chapter 7 Radiation (PDF, 597kb) Chapter 8 Particulates (PDF, 2mb) Chapter 9 Conclusions Glossary Index (PDF, 1.7mb) And don’t bother with the excel ‘report’ on the webpage, nothing available as far as I can see. https://www.southwark.gov.uk/assets/attach/7491/NO2-Diffusion-survey-data-2012-2022-all-data.xlsx

Please keep the thread on topic, this is about the Council publishing data on traffic and pollution levels in East Dulwich for local residents. Trying to get this lounged by going back to you know what’s that are now a permanent feature is just trolling - so do go away if you are not interested in pollution and traffic congestion in East Dulwich. Quarterly figures would be fine I think, as long as the Council added some analysis around peak pollution levels. People can find the raw data once it’s published. I think the issue at the moment is none of it is accessible at the moment - last update was Sept 22 I think, so where is Dec 22 and March 23?

I could quote a whole lot of words from Southwark, about what they are going to do, which just end up as empty rhetoric. So at the moment it would be nice, for the simple act of updating the dashboard. The ATCs are still I in place and I would assume collecting data - so can they please just publish the data and make it accessible to residents in East Dulwich.

Thanks Ex, interesting information. I think ideally I would like Southwark to concentrate on publishing activity that leads to poorer health outcomes. 1. Peak levels of NO2 and PM 2.5 during rush/school run "Exposure to PM2.5 can cause illnesses like asthma, COPD, coronary heart disease, stroke, and lung cancer. There is also evidence that links PM2.5 to low birth weight, diabetes and diseases such as Alzheimer’s and Parkinson's" - "the current UK limit is four times more than the updated level recommended by the WHO" Taskforce for Lung Health 2. Congested (idling) traffic on each road and timing "Traffic congestion increases vehicle emissions and degrades ambient air quality, and recent studies have shown excess morbidity and mortality for drivers, commuters and individuals living near major roadways" Zhang K, Batterman S. Air pollution and health risks due to vehicle traffic. Sci Total Environ. 2013 Apr 15;450-451:307-16. doi: 10.1016/j.scitotenv.2013.01.074. PMID: 23500830; PMCID: PMC4243514. 3. The percentage of individuals diagnosed with asthma on roads that have the highest levels of congestion and PM2.5 and NO2 within Dulwich/East Dulwich compared to the roads with the lowest levels of PM2.5 and NO2 during peak rush hour/school run. The Taskforce for Lung Health also stated - "The quality of air pollution monitoring varies by area, and there is a lack of accessible information for people to view air pollution in their local area. The public accounts committee reported in October 2022 that it is ‘too difficult for the public to find information about the air quality in their local area’. Everyone deserves to know if the air in their local area is safe to breathe. We need to make sure we all have information to help protect our heath. The government must act to ensure that people are aware of the pollution where they live and the risk they are at." I think that East Dulwich residents have a right to accessible and accurate information.

It's a thread about the Dulwich Streetspace Data Dashboard and about traffic and pollution in East Dulwich right now - specifically asking for the dashboard to be updated and asking about how these are measured. It's not about LTNs despite the OP labelling it as such.

I would like the dashboards updated and pollution levels measured on East Dulwich Grove as promised by Southwark Council, I think it's my right as a resident to have detail of congestion and pollution on my road. I do not believe that Pneumatic ATCs are accurate during congested traffic due to my own independent research of MetroCount 5000, but even so, even the flawed data is something. "In 2022, London’s rush hour was the slowest moving in the world, according to the latest Traffic Index. The average speed of motor vehicles in the city centrr during peak hours was just 14 kph (around 9 mph)".(Matthew Beedham Editor of Shift15.02.23) "Vehicle speed measurement equipment performs poorly when measuring low speeds of around 10km/h" (Bouygues Energies & Services introduces Energy Vision, an innovative solution designed to help manufacturers manage energy and decarbonise their business). ATC pneumatic counters are recommended to be used in 'are only designed for free flowing traffic" and "vehicles travelling very slowly might not be classified correctly" "either not included in count" or "placed in an unknown vehicle class" " Some councils have chosen to exclude all traffic travelling under 10Km/hr as in Enfield - a deliberate choice to change the default setting"- MetroCount - manufacturers of ATCs used by London Councils. Enfield manual count compared to ATC count on boundary road in Enfield during period of congested traffic - 57% of traffic missed.

Blue and yellow butterflies in the garden 🙂

I would like to know the amount of traffic on East Dulwich Grove, even if Jenjenjen does not. It's not an LTN thread it's a what is the traffic on my road measured by a Pneumatic Traffic Counter that cannot register any vehicle travelling less than 20km/per/hr thread.

Went in happy to be impressed.... came out with nothing. Partner excited about their preferred shampoo, until they realised buying in bulk as we do...it was cheaper. Some very cheap IT hardwear connectors, would be interested in how long they last. Ended up going to Bora veg shop and bought some very good resonantly priced (compared to some outlets) quality veg. I’m sure i I will use it, but don’t eat sweets, biscuits or hot pastries... so I’ll see. It was busy though.

The queues of traffic and pollution every morning caused by the LTNs remains. When it goes back to pre-LTN levels and there is not a queue of traffic idling all the way from LL to Village Way, then I'll stop discussing it on this thread. I'll even stop discussing it if Southwark actually measure the particulate pollution and NOx levels at 8:30am on a school day and publishes the data, or start measuring 'congestion' rather than ATC traffic counts from ATC's that do not register idling traffic. So yes, I'm sure it is an annoying and very long discussion for anyone who is not harmed by this polluting traffic or doesn't care if anyone else is.

‘The Times approached eight inner London councils that introduced LTNs during the pandemic to ask what settings they had used on their counters, whether they had been adjusted after their schemes were implemented and whether they were confident in the accuracy of their data, but none of them answered. Almost all of the councils have presented their LTNs as a success, claiming traffic reductions even on some boundary roads‘ In one case undercounting by around 1500 cars in a 12 hr period on a boundary rd.

Every time I say the traffic has increased on East Dulwich Grove, I’m pointed to the ATC counts on ED Grove Central .... which is often congested with slow, idling traffic - that the traffic has reduced. Although strangely increased by 25% at the other end. I know this is incorrect as I see, smell and hear it. So why do the ATCs that Southwark have used not count the traffic I see? Even more chilling is that the manufacturers of the ATCs now admit that Councils have ACTIVELY removed slow moving traffic data. So undercounting and removal of data. In the Times today, sadly a paywall, but I’m sure someone can take a screenshot. This is the data that was used to ‘prove’ that LTNs do not increase traffic on major resedential roads outside of LTNs.

The 'Active Travel Academy' at Westminster University is funded by grants from organisations promoting LTNs, cycling, cargo-bikes and 'active travel' - the Academy is headed up by Prof. Aldred. Maybe we should ask the Vegan Society to investigate if a vegan diet is healthy and the Meat Marketing Board if a diet that includes meat is healthy? Maybe Boris Johnson should investigate Party-gate and write the report?

Calling people 'daft' and 'thick' is rather rude. Do better.

Frying bacon emits 2.35 (2.22 ) μg/min of PM2.5.

Yes my partner saw jays on Greendale.. I love them, exotic looking and very bright ..as are all corvids.

That piece of research would be expensive and longitudinal .... it will not happen as anyone with meat in the game has no interest in ‘proving’ LTNs do not reduce pollution as over a Null hypothesis.
