M5 crash

Deep condolences to the people affected, but calls for the 70 limit to remain are irrelevant. Instead of driving by numbers, we should drive according to context. Some accidents are genuinely unavoidable – and the more we learn about this one, the more it sounds as if it was a freak event – but any crash is yet another reminder that phasing in an advanced driving test is long overdue.

Traffic system reform could fund fusion power. And more …

As explained here, and developed in an article yet to be published, traffic system reform can not only make roads safe, convivial and less congested, it can provide annual savings of tens of billions. In this Observer exchange, Craig Hitchings asks, “How likely is it that we’ll be able to harness fusion power before we run out of fossil fuels?” Physicist Brian Cox replies, “If we were to invest in it properly, then very likely, because the technology has been proved … The most effective fusion reactor is in Oxford, and it works. The problem is that no one’s demonstrated a commercially viable reactor. That’s why government money is needed – it’s a 20- to 30-year investment … We’re talking single-figure billions.” Cox adds, “Science is the foundation of the global economy – a significant part of it relies on the transistor – there are billions inside every home computer. Earlier this month, Osborne announced funding for science projects, including £50m for research into graphene. More powerful electronics, stronger aeroplanes… pretty much anything you can think of, graphene can improve. A lot of credit goes to the science minister, David Willetts, for making his point over and over again.” So far I’ve drawn a blank with the Cabinet, but if I keep making the point that money spent on traffic control is money misspent, and that reform will solve many of our congestion and road safety problems, as well as provide huge beneficial spending cuts, which among other things could fund fusion power – will anyone listen? David Willetts?

Numbers v context

On the Today Programme the other day, a road safety spokesman (I missed his name) said the only way to reduce accidents is to reduce speed limits. He wants 20mph in all urban areas. As I’ve written elsewhere, would you want to be hit by a bus doing 20? Nor would I. The Today Programme can be relied upon to air conventional arguments at the expense of provocative ones. The point, surely, is to drive according to context, not by numbers. If pedestrians are around, especially children, ket us proceed at walking pace so we can deal with the unexpected. In an equitable trade-off, if the road is clear, let’s drive at our own chosen speed rather than in fear of reprisal for not matching a number decided by an absent regulator. No sane person wants to hurt another, and that, combined with our instinct for self-preservation, will see to it that the chosen speed is the one that fits the circumstances. You can’t legislate for the insane, so why straitjacket the sane?

Nudge theory and Equality Streets

On PM today, head of nudge unit Dr David Halpern said, “People want to do the right thing but they don’t always have the information”. More to the point, certainly where road-user interaction is concerned: people want to do the right thing (take it more or less in turns), but prevailing culture and regulation make them act against their better nature.

Noisy but nifty

A comment thread about some of my traffic videos was brought to my notice here. It contains a video of Hanoi traffic – noisy but nifty, with no hostility or needless delay.

Greening not green

The outgoing transport minister didn’t even reply to my overtures when the Coalition took office. Any hope that his replacement, Justine Greening, would present an open ear were scotched when she said on R4 that transport “offers great challenges and opportunities, such as Crossrail and high speed rail.” In shaving mere minutes off the journey between London and the North, HS2 will doubtless end up costing two or three times the estimated £32bn; and it will cost the earth, especially the beautiful part of Earth called the Chilterns. Meanwhile, what about the scope in traffic system reform for transforming road safety, journey time, air quality and quality of life? Not a word.

Censored

Interesting to see authorities and media lumped together in this Guardian piece about the Wall St protests. I’ve been doing it for some time re. my efforts at traffic system reform, which are falling on stony ground in both government and media. Oh, I get the odd invitation to brief an MP, and the odd response from newspaper/TV/radio editors, but mostly it’s a brick wall, and nothing meaningful happens. Increasingly I think their resistance to change amounts to collusion in a system which, in the words of Kenneth Todd, “causes untold injustice and harm”.

The “bible”

Not all traffic engineers are fools, but they have inherited a defective (priority-based) system which gives rise to the torture rack of traffic control and is rarely questioned, partly because it is enshrined in a book known in the profession as “the bible”, so dogmatically are its tenets applied. Its characteristically long-winded title – The Traffic Signs Regulations and General Directions, is usually abbreviated to TSRGD.

Improper nomenclature

As mentioned elsewhere, traffic authorities refer to a driver who disobeys a red light as a red light jumper (RLJ). But what if you proceed carefully, after checking there is no conflicting traffic? In the eyes of the authorities, you’re still an RLJ. Doh. It’s only crossing at speed that is dangerous – the speeds encouraged by priority and signals! Should traffic lights be banned on the grounds that they encourage inappropriate speed and take our eyes off the road?

80mph limit?

The biggest guff spouted on the subject is that raising the limit will increase emissions by 20%. No, it’s not mph that matters – it’s rpm. At 70mph, old petrol cars rev at 3,500rpm. Longer-geared diesel or newer cars rev at 2000, using about a third less fuel and producing a third less CO2. On safety, what about middle-lane blockers who not only waste motorway space but cause bunching and get away scot-free when “accidents” occur? But the whole “debate” – about driving by numbers instead of context – is puerile.
