If there is traffic at roundabout then I might consider using the bike lanes.

Maybe I panicked . . . . . . based on long & bitter experience over the years . . . .
Thank you for your email.

Please be assured that works are not yet complete - the footpath is yet to have a 20mm overlay constructed and the levels will be regulated where necessary to provide an even surface. If you would like to discuss this, or any other of the cycle route construction issues further, the supervising engineer on [ phone number ].

Kind Regards,

The picture on that linked article is nothing like Dutch or what you'd see in the Netherlands:

It's hard to know where to start with the problems in the pictures: the lack of barriers between most of the cycleway and carriageway, the stupid angles that both parties are having to look at some of the intersections, the "give way" markings missing from some entrances, the proliferation of signals, the one-way cycleway, ...

Is that what they've actually built? Double-Dutch, perhaps!

Dodgy Dutch Bicycle Roundabout

27 May 2015 - 2:39pm
On the way to Pimlico From Battersea car boot sale I passed the redone roundabout at the corner of Battersea Park. It looks like a roundabout that you would see in the Netherlands. It has a separate isolated bike lanes around the perimeter. It looks kind of complicated regarding who has priority. I am a cowardly( but fast) cyclist generally I decided that I aint using that cycle lane. I have got used to roundabout in the normal way.

Agreed. It would be useful to us all if both parties sued the agency that's responsible for this road layout.

If the bike lane was a road with cars on it, It would still be unclear who has priority. It aint no T junction.

The peelers here have the sneaky radar binocs out quite often. I saw a car stopped last Saturday with a gendarme leaning in the window. Oh what fun.

One way it has arisen is when a highway authority designs a cycle lane or track across a private minor road, their safety auditors chicken out and demand the cycle lane (incorrectly IMO) gets give-ways painted on it and then the private road owner paints give-way markings inside their boundary (which usually aren't there previously).
Here's the nasty example from the A148 Hardwick Road King's Lynn which was created by something like the above process, with the council adding give-ways contrary to policy and then the private road owner adding a give-way too.

As recently as 2011 this had the usual Norfolk white-edge-line layout which you might be able to see in https://www.google.co.uk/maps/@52.74281 ... e0!6m1!1e1

They certainly do it in France. Driving up the Autoroute yesterday, at my sedate 70mph (sedate for France that is, the limit is 130 Km/h ~ 81mph), I was puzzled to see a lot of approaching motorists on the other carriageway flashing their lights. But only for a moment, the reason soon became clear as I passed a pair of Gendarmes parked up on the hard shoulder on their powerful motorbikes. And sure enough, a few minutes later they came hareing up past me at top speed, blues flashing and weaving in and out of the cars with complete abandon. And a little further on, I saw they'd pulled someone over. And were presumably giving him the treatment - and this being France, I guess it wasn't of the "'ello 'ello 'ello!" variety!

I continued at my 'modest' 70mph...

The design in the second PDF here https://departmentfortransport.wordpress.com/2015/05/25/cityconnect-youll-get-what-youre-given/ (CityConnect's statement) looks similar? Apparently from the (old) London Cycling Design Standards 2005 edition.

Re: Ian Austin MP - Couldn't make it up

I don't think the bar is set particularly high. Certainly when I have to drive to London, I put the Mezzo in the boot and park in the outskirts, usually a shopping centre car-park (sometimes the hotel if staying over). This allows me to avoid the congested centre (where driving is never a good idea) and take advantage of the lower parking (and hotel) charges in the peripheries.

I'm sure MPs have allocated parking spaces. As many businesses are now doing, it would be advantageous if these were reduced: Healthier lifestyles are proven to aid mental abilities (and they need all the help they can get) and fewer cars in Westminster would mean less opportunity for car-bombing the HofP, which must be a Good Thing.

Musn't it?
Anyway, fewer MPs driving, more cycling would definitely be good.

Are we not setting the bar a little too high here?

Is it "all or nothing"?

If anybody could persuade me to take my car to London (which wouldnt be easy) then I would want to do the whole journey in the thing and not break the journey up with extra load transfer between car and bike. I bet he already has a parking place at Westminster, so this would save putting an NCP charge on his expenses.

Shouldnt we be saving the condemnation for all those people who's journey was within London and could have not touched the car at all that day.

Re: Is a cadence sensor worth it?

The computer that I ordered is seemingly coming from Germany. It didn't mention that on the famous bookseller's website when I placed the order. Anyhow, it's left Germany, got across the North Sea and has entered and left (yesterday afternoon) somewhere called Gbcvta GB (I believe that that's in Coventry). The delivery estimate is down as 17 June though. I'll see if the tracking updates with a better indication today but if not, I'm cancelling and re-ordering. That may seem strange but the famous bookseller themselves are now selling it themselves (rather than through a third party) - and it's a fiver cheaper!


Arrived 20 minutes ago.

Rochester Row car park? NCP Victoria? Guildhouse Street? Park up and walk (you know it makes sense), it would be quite simple to have planned to do that. Better still, pack a folding bike, park further out and cycle in.

Err.... steady on guys.

I just looked up the story on what may be a more trustworthy source: I can't vouch for it.

It seems this guy had driven down from the West Midlands that day, and it was just the last mile of his fairly long journey in which he got caught in a snarl-up. This sort of thing has happened to me oodles of times (usually on the M25 ) and I won't deny just how annoying it can be! I don't know why he didn't go all the way by train but he may have had good reasons.

He apparently responded to people who tweeted "why didn't you walk?" with the reply that he "couldn’t abandon his car on a London road." Seems reasonable to me. One extra parked car on the street would only make things worse!

I don't know what the black cabbies' dispute is about, but I can understand people feeling a grievance. I'm sure that on those occasions when I partook in a Critical Mass on our capital's streets, there were some folks about that would have been not wholly favourable to us cyclists. That's human nature! And I've had the odd 'moment' with a black cabbie myself....

Re: Roadcycling fimed whit pro drone in 4k definition

the next thing for racing cyclists with back side in the air - dont need to look ahead use a drone with camera floating just above as eyes?

I think the chap who invents teleporting of MP's to a far distant planet, one way, is worthy of the billionaire club. If you go online to paliamentary expenses, even though they've curbed their excesses there is still a lot to question....regular first class train travel when 2nd would be fine etc. Though in Mr Austins case the taxi fare may be far lower than the expense claim for wear and tear of artisan crafted leather shoes.

On a side note to do with the distance, I think it was nicholas crane on his maps programme who pointed out to underground passengers how short the distance was between particular stations. It was just that people viewed the underground map ( as it has no defined linear scale ) and went station to station.

But the drone's camera angles are really fun and some amazing new shots to be had!

I can't have my life's work dismissed so casually

'4k at 30fps is essentially SD for any moving content' Mmm, well there is a lot going on here which needs to be looked at in order to explore this one. First of all, the constants are pixels and resolution, ie. how many. In other words resolution is the number of 'dots' can be squeezed in to a space. An A4 picture at x resolution will look sharper than an A3 picture at x resolution, so screen size plays a part too. SD, HD, 4k etc are not safely defined but generally accepted in the UK for television broadcasting as 576 interlaced for SD, 1080 interlaced for HD. So, a UK HD TV will have 2.07MP per frame, this is 5 times the resolution than SD. This is the definition.

Lets explore the frame rate now. 30 frames per second is the default US ATSC frame rate adopted due to the use of 30hz mains electricity. In the UK it is generally 25fps and in cinema 24fps. You mix up fps and hz but assuming you mean frame rate, does a faster frame rate give a sharper picture? Well, the human eye can detect frame rates higher than current TVs display, but not much more. Lets go back to our 35mm film cameras, if we want a really sharp image, we would try and get as fast a shutter speed as possible. This would lead to the iris opening wider which would reduce the depth of field. We would freeze the action whilst blurring everything else. It was a compromise which we utilised to get the image we wanted. The same with moving image cameras, the faster they record a frame, the sharper the image. So in this respect, you are correct, a faster camera gives a sharper image. But there are limitations, such as, light levels, lens performance, sensor (film) sensitivity.

So how has the film industry coped with these limitations over the last 120 years? They have maximised and controlled light, developed fast lenses and probably the single most important development, perfected mounts and tracking systems which move with the action, thus 'freezing' it within the frame.

The real issue is that the rest of us just want to film an activity with our GoPros but have no control over lighting and may not have access to tracking and panning equipment. They might be mounted on our helmets or handlebars. Of course the result is going to be less sharp, and to be honest, a frame rate of 300fps is only going to make the footage less watchable!

Are they silly numbers then, no. The numbers indicate to us what we can expect to achieve. For most broadcasters and film makers, that is an excellent watchable product.
