For context / contrast, I believe the average person is stuck in traffic for 38 hours per year.

I doubt if I am in a car for 38 hrs per year

I nearly changed it to average driver. I'm not sure which of the two figures I found was correct. One said motorist, the other said person. And there is a difference.

Yes driver. 38 hours per year, cost of £30bn+ to the economy. The JSO protest cost £765,000 to the economy. |

You might have a large number of vehicles on other roads that were minorly disrupted (~minutes) by increased traffic flow due to traffic avoiding the main protest. But you could have a significant number that had major disruption (~hours) because they were held stationary on the motorway with no way off. This could (and I do believe did) involve emergency vehicles. The arthimetic mean in this case then is unhelpful and we'd need to look at the distribution and how these values have been determined to understand the impact in a more useful sense. Oh, a straightforward analysis using the arithmetic mean - absolutely. A few cars were stuck for ages, probably quite a lot of cars were only mildly inconvenienced. But I'm surprised no-one in the MSM has pointed out that average as it seems like an obvious deflection observation. I wasn't really posting it to suggest that the real impact was minor, though in the grand scheme of things (e.g. when pitched against paul's observation above about the 38 hours, which I would expect is similarly based on the arithmetic mean) it was relatively minor. *Could have been* much more significant though. |

Again, larkim wrote: it was relatively minor. *Could have been* much more significant though. Based on what context thought? If you're taking all traffic in the greater london area, or whatever and saying it's an average 4min delay, then yes, it looks minor. If you're taking an emergency services ambulance on the M25 stuck for 4 hours with a rapidly deteroriating patient, then the impact looks unforgivable. That's why the context and critical interpretation of simplistic stats like that is important. |

I was stuck for 20 minutes this morning because they'd sent street sweepers out on the main road between Grimsby and Louth at rush hour, because they'd surfaced dressed the road this morning just before rush hour. Then every road into Great Grimsby's historic and bustling city centre is controlled by temporary traffic lights adding at least 10 minutes to a return trip to town, and they're doing roadworks on both bridges that cross the Dock that bypass the city centre, one of which has been closed for 18 months now, which adds 10 or 15 minutes each way between the parkour gym and Sainsbury's. So that's an hour's delay so far this week. I can see 38 in a year quite easily, and I only do 1000 miles a month. |

Which is why my first question was how have they calculated the 51k hours and 710,000 vehicles - I know the M25 is busy, but given the estimate of the daily useage of the busiest parts of the M25 is 200,000 *per day* (source: https://www.cityoflondon.gov.uk/things-to-do/history-and-heritage/london-metropolitan-archives/collections/m25-motorway), that 710,000 vehicles looks wildly out of context for calculate a genuine acute impact.
