LBHF are conducting a consultation on a 20mph speed limit in the Borough.  The main question is will it extend to most main roads or not, The cluster map below shows the location of cyclist fatalities and seriously injured from 2005 until recently.


When we combine the Pedestrian and Cyclist casualties the  results show a similar cluster around main roads, where people are going about there business. The cluster map below shows casualties from 2005 to 2014 from the police’s STATS19 data


The LBHF consultation is live until 31 July 2015. Whether you are a pedestrian or cyclist or motorist we urge you to make all main roads 20mph to produce a civilised Borough. Each household should receive a printed version of the questionnaire in the post.

But to make sure further Information and an online version of the questionnaire can be found here:

Please go there and fill in the questionnaire now. Say YES to the first question.

Nitrogen dioxide is a noxious gas given out by petrol and diesel engines, but particularly by diesel engines. It aggravates asthma and leads to many early deaths.

On 4 February four members of hfcyclists, joined by Andrea Lee from Client Earth set off to place 33 small NO2 detection tubes around Hammersmith Gyratory and Shepherds Bush Green. They were collected and replaced on 4 March, and the fresh tubes will be collected a month later. We hope to get the results sometime in April.


John Griffiths, Chair of hfcyclists, placing an NO2 tube

London Borough of Hammersmith & Fulham measures NO2 / pollution in a few locations around the Borough, but at a height of 3m. Our tests are to show if NO2 pollution levels are higher in places where the NO2 may be concentrated because of the local geometry and prevailing winds. We also want to see if the levels are  higher at breathing height and push-chair height.

We hope to use the results to inform and influence those making traffic decisions at Hammersmith Gyratory and Shepherds Bush Green. If the results turn out to be of general interest we will consider how to broadcast them more widely.


Several tubes will be used at each site, so there are not 30 separate sites. We are looking at places where there are a lot of people crowded together with a lot of traffic. The local geometry and prevailing winds can concentrate the pollution in certain areas.





Because of the potential for interference when tubes are placed at a lower height LBHF only place tubes at a height of 3m. Pollution levels lower down and closer to the source are expected to be higher, but we do not know by how much. We will be measuring at two heights, 3.0m and 2.25m at the same location. We hope that by extrapolating, this will give us an indication of the NO2 levels at 1.5m,  approximately breathing height.


An NO2 monitoring tube in situ

At a couple of places where we do not expect any interference to the tubes we will be measuring at heights of 3.0m, 2,25m, 1.5m and 0.5m. This may give us an indication as to whether children in pushchairs are exposed to greater levels of pollution, and by how much.

It should be pointed out that NO2 diffusion tubes are not considered a very exact method, and measuring for only two  months out of a year will not lead to very robust results, and they may be described as “indicative”.

We will use statistics on our results to see how much reliance can be placed upon them. However we do hope to  extract useful information from these tests that may be used to inform people making traffic [and health] decisions.


The level found for 2013 at the Hammersmith Broadway NO2 diffusion tube site was 89.5 microgram / cubic metre. The EU guideline  for the maximum value is 40μg/m3 . Levels above 60μg/m3 could lead to a potential exceedence of the NO2 hourly mean Air Quality Strategy objective.

This is an important consideration that traffic planners must take into account when deciding whether to give space to pedestrians and cyclists or to motor traffic.


We did not find any consistent difference between the values at 3.0m and at 2.25m. We were surprised that at some places the values were higher at 3.0m than at 2.25m. In the circumstances we combined the values at the two levels to give an average for that location.

This also meant that we could not extrapolate to estimate the NO2 concentrations at normal breathing height. However we were able to find how the NO2 values varied around our locations and how they compared to the NO2 value at the LBHF reference point.

At the two locations where we measured at 4 different heights we found a gradual increase in NO2 as we descended to pushchair height.

It is possible that the proximity of the Hammersmith flyover may have affected the height distribution of NO2.

We applied corrections

a] for the difference between our reference tubes and the readings from the Automatic Monitoring Station at Shepherds Bush Green.

b] to estimate an Annual Mean by taking into account how our months compared to the general trend over the last year.

On the following pages are charts showing the adjusted values. The EU limit is 40μg / m^3 [40 microgram per cubic metre].

1] The NO2 values were all well over the EU limit of 40μg / m^3 [40 microgram per cubic metre]. Most were more than 2x the EU limit.

2] In Hammersmith all the values apart from the one in Beadon Rd were greater than at the LBHF reference location by St Paul’s Church. This may be due to the Canyon Effect where in enclosed places the pollution is concentrated.

3] At Shepherds Bush Green there is an Automatic Monitoring Station. Around the area all the values are higher than at the monitoring station. The closest LBHF tube is on the Uxbridge road and does not have a very high reading.

4] At present LBHF uses indications of the NO2 pollution levels that are below those that actually exist in some of the busiest spots. To bring these values down to the EU limit some extraordinary measures must be taken. One such would be to encourage a massive modal shift towards cycling for shorter journeys. This would involve using the road space to encourage cycling.

5] Whilst we only measured NO2 values in two locations at pushchair height, we found the values at 0.5m to be about 30% greater than at 3.0m where LBHF makes its measurements. At a buggy height of 0.8m the NO2 value is about 25% greater than at 3m. Young children with developing lungs are especially vulnerable to the effects of NO2 pollution.

Draft Hammersmith Cycling Strategy

Hammersmith and Fulham Council have a new Draft Cycling Strategy which is now in the final days of consultation, with comments due by this Friday, 16th January – Now Extended to 2nd February 2015.

ou can review the strategy in full here and complete the council questionnaire. The strategy has taken on board briefings made by hfcyclists but does not yet contain firm commitments on how to deal with every barrier to cycling in the borough as identified in Space For Cycling. There is support for tackling major junctions, providing space for cycling, filtered permeability and 20mph so the tools are in discussion.

A proposed cycling network is also shared at the current high-level stage where not all alignments have been finalised. A positive sign is that there are two east-west superhighways proposed but unfortunately only the northern one is likely to continue all the way into town. The indicative quietways are likely to be many years away, and the junction improvement at Hammersmith Broadway by June 2017. Out most likely early change is to be 20mph and changes around Hammersmith Bridge.

Let us know your thoughts below, here is a quick summary of the key items in the council’s strategy aims, but you should review the full strategy here.

The primary purpose of this Strategy is to increase the number of journeys made in the Borough.
The key objectives of the Cycling Strategy are:

  1. Enhance and extend cycle routes to create a comprehensive network
  2. Create more space for cycling to improve cycle safety
  3. Improve interactions between road users to reduce the perception of the risk of cycling
  4. Provide more cycle parking and cycle hire locations within the Borough

This will be achieved in a number of ways:

  • Collaborating with TfL on the development of Cycle Superhighways to extend the cycle network;

  • Implement a network of Quietways building on the existing cycle network;

  • Working with TfL on creating more space for cyclists through the Better Junctions programme;

  • Create a safer environment for cyclists by introducing 20mph speed limits across the Borough;

  • Provide cycle training for children and adults to increase participation and confidence in cycling;

  • Provide training to increase awareness between different road users and cyclists;

  • Increase the number of cycle storage and parking options;

  • Develop and expand the Barclays Cycle Hire scheme within the Borough; and

  • Ensure that new developments are designed to encourage cycling and provide adequate parking.

Space For Cycling – The Final Push

Our space for cycling campaign has now been contacting candidates for the local election for some weeks. Using feedback from over a hundred involved local campaigners we have devised a particular proposal for every ward in Hammersmith and Fulham. These ideas each use a theme which relates them to the Space For Cycling campaign throughout London.

You can check the proposal for your local ward, see which candidates support it and contact your candidates to urge further support.

You can also ride with us on Saturday 17th May. We are meeting at 10AM on Brook Green at foot of Dunsany Rd. Experienced cyclists will lead cyclists of all ages including accompanied children to a ride on closed roads starting on Park Lane. Join us on the ride to show your support.

At the time of writing we appear to have support from the Green Party, Liberal Democrats and Labour across the borough. We remain optimistic that there is further support to be had, as there are some very important issues on road safety and enabling cycling as a choice for transport locally. For both candidates and those seeking to better influence them we have produced a detailed guide to the entire campaign and the issues we feel it can address.

Ride with us to call for Space For Cycling

As part of Space for Cycling there is a Big Ride in the centre of London on Saturday 17th May. We will be leading a ride from our usual spot on Brook Green by the tennis courts (foot of Dunsany Road) with experienced cyclists providing a safe route to and from the ride itself which will be on closed roads, free of motor traffic and at a sedate, campaigning and enjoyable pace.

We will aim to gather by 10AM then set off shortly thereafter. The main ride gathers at Park Lane around 11AM then from Mid-day will depart for a ride along motor traffic free roads towards the Embankment where there will be a rally from 1PM to 2PM. We will aim to provide a ride back to Brook Green upon completion of these events, due back by around 3PM latest. People are free to leave earlier should they wish, or to join us there, though given that last time saw 10,000 riders brave rain and we’re hoping for sun, it’s vital to be distinctive…

LCC Big Ride Route 2014

Please tell your friends, bring your family and help us make the biggest possible push for Space for Cycling. You can sign up to this ride on FaceBook or send an email to your friends about it linking them to this page. The more the merrier.

This is about sending a message, so whilst we will have flags, leaflets and other materials to distribute we’d like you to bring a message. It may be a slogan of your own, or one we can help provide, but the important thing is to represent why you’re on the ride in the clearest possible way. Your message can be fun, especially if you’re young or young at heart. We will doubtless be ringing bells and making noise along the way.

We’ll be printing out and laminating a range of slogans on A4 for distribution at the start of the ride, and we’re taking suggestions for slogans.
