| Post subject: | LTI vehicles top pollutants. |
The Author of this report has been asked to clarify the distinction between LTI type vehicles and saloon type vehicles. The reason being is that in this particular instance the use of the Generic word "Taxi" is highly inappropriate. The following is the press release taken from Imperial College website with the make of the offending vehicle added by myself. In future, it would be less misleading and more desirable if these researches would clarify their subject matter more accurately. Now we know that LTI are the top pollutants I wonder if and how they will defend their position? I also wonder what "Leicester council" and "Allied" will make of this when they read it? ............................................................................................... Taking an LTI London Black taxi could increase your exposure to pollution. For immediate release Tuesday 10 January 2006 Researchers have discovered that your level of exposure to pollution can vary according to what method of transport you use, with travelling by LTI London type taxis resulting in the highest levels of exposure and walking one of the least. Research published in the journal Atmospheric Environment, describes how the team from Imperial College London and the Health and Safety Laboratory, Buxton, measured and visualised exposure to pollution levels, while using a variety of different transport methods for travelling across London. The researchers looked at five modes of transport, including walking, cycling, car, London taxi and bus, and measured levels of exposure to ultrafine particles when travelling on them using a newly developed system that uses in combination an ultrafine particle counter and video recorder. Walking to work may result in least exposure to pollution Ultrafine particles are less than 100 nanometres in diameter and mainly traffic related. Their small size and large surface area means it is possible to inhale large quantities which makes them particularly dangerous. The visualisation system allows video images of individuals activities to be played back alongside the ultrafine particle concentrations they are exposed to. As a result, most activities and behaviours that cause high exposures can be visibly identified, such as being trapped on traffic islands and waiting in congested traffic. On average, while travelling in a LTI London taxi, passengers were exposed to over 100,000 ultrafine particles counts per cubic centimetre (pt/cm3), travelling in a bus resulted in exposure to just under 100,000 pt/cm3, travelling in car caused exposure to 40,000 pt/cm3, cycling was around 80,000 pt/cm3, and walking was just under 50,000 pt/cm3. Surbjit Kaur from Imperial College London, and first author of the paper, said: "It was a real surprise to find the extent to which walking resulted in such a low exposure. The higher exposure from travelling in taxis may come from actually sitting in the vehicle while being stuck in traffic where you are directly in the path of the pollutant source. Also the fact that taxis are probably on the road for much longer than your average car could cause an accumulation of ultra fine particles." Dr Mark Nieuwenhuijsen from Imperial College London, added: "The particular strength of the system is the visual aspect. The new monitoring and visualisation system is an effective environmental risk communication tool that can be used to identify, visualise and avoid hotspots of pollution." The study was carried out as part of the DAPPLE (Dispersion of Air Pollution & Penetration into the Local Environment) project, which looks to provide a better understanding of the physical processes affecting street and neighbourhood scale flows of air, traffic and people, and their corresponding interactions with the dispersion of pollutants. The project consortium includes the University of Bristol, the University of Cambridge, Imperial College London, University of Leeds, University of Reading and the University of Surrey. DAPPLE is funded by the Engineering and Physical Science Research Council. Further information about the project and exposure visualisation samples can be seen at www.dapple.org.uk |

Crazy that the London cab trade are going out of their way to kill off all their trade. Still at least the good people of London now have a choice of licensed vehicle. And thank the lord most of them are seeing the light and coming our way.

Someone better tell the travelling public then Ollie. I'm busier than ever, and its only January.
I have noticed a lot more Minicabs devoid of customers though. Very sad.

Talking about your mob, if you were anywhere near Charing Cross Road last night, you would have seen the wonderful sight of two licensed Minicabs sitting on a couple of tow trucks after the TFL Met unit arrested their drivers for touting near Taliban Taxees old office. Apparantly they are now applying to the courts to have their ' Licensed Minicabs ' crushed upon conviction. Now this could be the best detterent yet for the little people!
So if you fancy eating your beans from a crushed Mercedes, turned tin, watch this space . . .

Now we know that LTI are the top pollutants I wonder if and how they will defend their position? I also wonder what "Leicester council" and "Allied" will make of this when they read it? So, let me try to fathom out what youhave done here. You take a report, do not like how it reads, and then fraudulently re-write it to suit your needs. Is that legal? Question one.when you questionably claim these vehicles are the most polluting, do you mean equally all TX11, TX1 Fairways, and FX4 cabs, and if so why? Question two. Is something not being done (in London) to combat this? ...............................................................................................

I suppose LTI will have a valid reason for being the top polluter in London. Perhaps the pco should bring in more stringent safety conditions such as the ABS breaking system, and emisions that meet the highest standards of those saloon cars, which were highlighted in this recent research?

I understand emmisons were the reason why they changed from the Nissan to the Ford engine? I was informed there is only point 3 of a difference in the emissions output between the two engines, which I undestand is negligible. That is not a qaullified statement, it is only what I have been told. So I stand to be corrected. JD |

It is obvious that this "report" is poorly researched. Blaming "Taxi's", then with a bit of unjudicious editing from a contributor, LTI. Theoretically, this could cover many vehicles, with different drive trains. For instance, FX4's with BMC engines, Fairways with Nissan engines, and TX 1/11, with Ford engines. It does not strike you as odd, that only LTI vehicles, and not Metrocabs, or Transit vans, with identical engines, are equally polluting? You would appear to be clutching at straws, publishing any bad press that LTI get, whether it is justified or not. If the publishers of this research did not qualify the term "TAXI", why do you take it upon yourself to claim they were talking about a whole product range going back over several years, and no other identically engined vehicles? A (not very well) hidden agenda perhaps? |

A (not very well) hidden agenda perhaps? The report states that the research was conducted across the city of London. How many types of vehicles do you know that ply for hire in the city of London? I know of only two. If you wan't to believe all the vehicles tested were metrocabs then don your rose tinted spectacles and close your eyes to reality. I don't know the ratio of LTI vehicles to Metrocabs but I would guess they outnumber them by 20-1. There must be someone somewhere besides the pco who knows how many of the 20,500 cabs are metrocabs? Maybe you know? lol JD |

But no answer as to why only LTI vehicles were targeted? No answer why a TX11 is polluting but a Transit is not, when they are sharing an identical engine? Cabs in London are surely the best maintained vehicles on the road, subject to constant checks, including emmissions. THis distorted report is complete wazz, as you well know, but, as usual you do not allow the truth to get in the way of what you view as a good story. |

I think this report is more to do with the exposure to emmisions, that means particles coming into the vehicle and not neccesarily coming from the vehicle itself. I suppose that means the LTI vehicles are full of holes lol Quote: Cabs in London are surely the best maintained vehicles on the road, subject to constant checks, including emmissions. I can't comment about being the best maintained. Quote: THis distorted report is complete wazz, as you well know, but, as usual you do not allow the truth to get in the way of what you view as a good story.
The report lacks clarity but I suppose you could always email them if you want the larger picture? Let me know what they say. JD |

London It would seem Taxis in London are accountable for 24% of air pollution. What can be done about it? Passage from one of many articles. As a first step, the city’s 20,000 taxis – which are currently responsible for 24 per cent of fine particles and 12 per cent of NOx emissions from road transport in central London – will have to meet strict emissions standards. The cost of converting them to reach the new standards will be met by a flat rate fare increase of 20 pence per journey from April 2005. All London buses will be fitted with particulate traps by December 2005 – reducing emissions of PM10 (and other pollutants) by over 90 per cent and making our fleet one of the cleanest in the country. These measures should reduce emissions, improve health and go a long way towards meeting the Government’s air quality objectives for the capital http://www.london.gov.uk/mayor/environm ... ssions.jsp http://www.cfit.gov.uk/pn/0303/ http://www.tfl.gov.uk/pco/pdfdocs/emiss ... n-date.pdf http://www.tfl.gov.uk/pco/downloads/emi ... egy%20.pdf http://www.london.gov.uk/view_press_rel ... aseid=4637 http://www.thisislocallondon.co.uk/news ... _green.php http://pistonheads.com/gassing/topic.asp?f=57&t=182732 |
