"Comparing the 3 years before the scheme was implemented and the 2 years afterwards, the number of recorded road casualties has fallen by 22% from 183 per year to 142 per year. During that period casualty numbers fell nationally - by about 14% in comparable areas." "Because the total numbers of deaths and serious injuries and of casualties by road user type and cause are relatively low, few inferences about the scheme's impacts should be drawn from these figures." ... "In conclusion, early figures suggest that the implementation of the 20 mph Speed Limit scheme has been associated with reductions in road casualty numbers. The scheme has reduced average speeds and been well-supported during its first two years of operation." Oh, and the roads with the limits were chosen for their low initial speeds: "Following consultation with the Police, six sectors were then identified for funding over two years to focus on residential roads, most of which had existing speeds equal to or less than 24 mph." So, just to confirm, merely putting up 20mph signs, and doing nothing else, has reduced casualties slightly more than in other comparable areas, though the difference is small. Other research shows that the speed reduction from signs alone is also small. The safety improvement may even be bigger than the casualty figures suggest, if the reduced traffic speeds encouraged more people than before to walk and cycle. Ermm. No ****wit. People don't cycle because it isn't a viable form of transport. -- Dave - intelligent enough to realise that a push bike, like a skateboard, is a kid's toy, not a viable form of transport. |

Yes, oddly enough I also read the reports about the installation of speed cameras where deaths fell by the same proportion and the assorted limpwits of URC claimed that the figures showed that speed cameras were a stunning success. That's because you haven't understood the difference between statistical variations in a proportion and a number. Seems those limpwits are more numerate than you. I can confirm that facts and figures are not Firth's strongest points. |

Did you read the article properly Tony? The numbers killed and seriously injured actually increased. "Analysis by consultants Atkins, on behalf of the Department for Transport, found the average number of people killed or seriously injured annually in Portsmouth rose from 18.7 to 19.9 after the scheme was launched in 2007". Derek C Considering natural variation and the numbers involved this looks like a non-significant change, easily explained by random variations -- 67.4 percent of statistics are made up. |

It seems that reducing urban speed limits from 30mph to 20mph has actually increased road accidents in the trial areas, while switching off speed cameras has reduced accidents in other areas. See: http://www.dailymail.co.uk/news/arti...one-increases-... Must be something to do with risk compensation, or motorists dying of boredom at 20mph! Or this... "The Portsmouth speed limit is not enforced by speed humps or cameras, instead relying on motorists obeying the law." LOL! Fat chance! My guess is that these motorists deliberately revolt against the restrictions imposed on them and what is the point of a restriction that is not enforced anyway? -- .

That's because you haven't understood the difference between statistical variations in a proportion and a number. I understand both, and in the case of speed cameras the sample size was smaller than the sample size in the case of the Atkins report, the proportion by which deaths were reduced was of the same order but in terms of number fewer people were "saved" by the speed cameras *at each site* yet the morons, and you can add your name to the list, claimed a staggering victory for speed cameras. That data was statistically useless for many reasons, regression to the median, pointlessly low sample sizes and even the choice of a "reference year" which had the highest number of deaths over a ten year period. Also the geographical extent of the zone protected by the speed camera was not defined before the "trial" was commenced. The Atkins report was performed in a more controlled manner than the trial of speed cameras and is founded on a greater body of evidence. Now, you claim that evidence that relates to larger numbers, and which is therefore slightly more sound a proposition on which to base an argument that a non-Null effect has been observed is flawed. You remain an idiot who wants things both ways. Seems those limpwits are more numerate than you. More wishful thinking from you. Add your name to the list of limpwits, you couldn't argue your way out of a paper bag. |

How jolly nice for you. I loved my Jaguar XJR. Are you saying that everyone should either have a Jag. XJR or a bike? FWIW I had both, so on the "use a form of transport you love" basis I scored 100% and was thus saving the planet! |
