There's a paper out: Pedal Cyclist Fatalities in London: Analysis of Police Collision Files (2007-2011) Anyone who cycles reading this must feel the fear of being in a followup article, becoming a statistic showing Britain is no less dangerous to cycle than it is today. Each of those numbers represents a death: someone's child, possibly a parent, possibly a partner. Dead.

It's a shame nobody from the BBC read this paper before their week of drivel. They could have visited a different junction every day, a cause of death, with discussion about how to make it safer. After looking at tipper truck left hook they might ask less about helmets; on pinch-point-killings their "mutual respect" story might be different.

Returning to the paper

Not only are HGVs a key form of killing, Tipper Trucks are the death of choice. This is something to highlight in engagements with the FTA and other truck-lobby-groups. It is not all HGVs that kill, it is tipper trucks. But why/

-are tipper trucks responsible for 37% of HGV miles on those routes people cycle? If not, are they significantly more or less?

-22% of HGV drivers had driving convictions. Is that spread evenly, or are tipper truck drivers more likely to have convictions? And how does that conviction rate compare to HGV and tipper truck drivers in general.

These are important details as they would help confirm the beliefs of many: tipper trucks kill more than other vehicle types. If it can also be shown that the conviction history of their drivers is higher, it may hint about their employment standards. If it also turns out that having prior convictions is a significant sign of future participation in a fatal RtC, it shows that the history has to be taken more seriously.

More succinctly: professional 747 pilots are held to significantly higher standards than amateur cessna pilots. The UK/EU standards for "professional" driving does not do so. Actions that would be careless in a car are invariably dangerous in an HGV: something the prosecution and penalties should take into account.

oad narrowing due to parked car is called out for the loss of control and collision with cyclist events. This shows why the parked cars should be between cyclists and motor traffic: a buffer. The WCC "death mall" proposals are the absolute opposite of this: painted into the swerving zones of both traffic directions.

ASLs. ASLs in front of HGVs are where cyclists go to die. If an HGV comes up behind you while you are in one, you would be safest setting off before the lights change. This is not a joke: remember it. 

"Hear an HGV, get the fuck out of the ASL"

This also highlights why ASLs are bollocks. While designed to defend against some actions (left turning cars at junctions), they entrap you into a new one "crushed by HGV drivers who forgot you where there while they were on the phone. " Because yes, "driver on phone" was listed as a distraction in two of the four deaths

Left turning truck: 14 fatalities of 52, slightly above 25%

We've all seen those videos that show the truck turning left over the cyclists. Some of us have even experience the terror of cycling on a road to see an HGV pull up alongside with its indicators on, warning it is about to left hook you. If that ever happens: brake hard and fast. 

Being in the same lane for straight on and turning traffic is listed as a factor —maybe there's not enough cues that the HGV will turn and so people slide up the side of the vehicle. Maybe if you can think you can get at least one vehicle in front of it at the lights it could be justified. Otherwise, better of overtaking.

There's also two cases where the HGV was in the straight on lane to turn left -on account of their size. That shows that HGVs are not suited to Britain's "narrow historic streets". If there isn't room for a cycle path on a road, there clearly isn't room for an HGV to turn.

Death by road narrowing: 7

Seven of these crashes are characterised by the cyclist ‘running out of space’ meaning that the available lane width narrowed forcing the cyclist and truck into closer proximity.
Of these, five crashes occurred at junctions – both the truck and the cyclist were turning left in two cases, turning right in one and travelling straight on in two. The sixth occurred as the road narrowed on the approach to a junction and the seventh crash occurred in close proximity to a pelican crossing on a build-out.

We all know those too. Its easy to say "give way to the HGV", but what happens if you are partway across and a speeding HGV barrels past then swerves in?

Helmets: 42% of the cyclists wore a helmet. Did they work? Clearly not. Did more or less than 42% of cyclists on the route have helmets?

The section on injury locations (p49) goes into detail on where injuries were sustained. Summary: get hit by a speeding car on squashed by a truck and injuries happen everywhere. Helmets do appear to do fuck all. P52 does compare what percentage of non-fatal injuries involved head injures: more than the fatal ones, which tend to be all-body. Even those numbers don't show which did have/would have their severity reduced by helmets. All we can say is the "if a helmet saves just one life" then the argument has to cover full body armour strong enough to survive a 7+ ton truck rolling over it. Just tell the fuckwit making the "Saves one life" argument to put a helmet on, lie down and let a truck drive over it. 

p53 looks at infrastructure in the specific, junction by junction, not london's roads per se. 

ASLs suck

cycle paths that abandon you at junctions suck. Think about this: junctions are the most lethal bit of the roads, yet cycling "infrastructure" abandons you at this, the most dangerous. Why? It's easy to paint something on the straight bits, making junctions safe is hard work AND MAY AFFECT TRAFFIC FLOW.

p57-71: infrastructure improvements

This is a compelling section, not so much due to any innovative ideas, but because they can look at their data and say "how much this would have reduced their fatality set". 

it is very powerful when you can look at proposals -here the WCC "admiral's blender" stands as a highlight and campaigners can tear it apart with data. They can go though a junction and say "which of these documented fatality classes are prevented in this proposal? Which are left? Why have they been left?"

ASLs get special mention here. They propose either a "no vehicle zone" or a special cyclists only phase. A no vehicle zone would just be more wasted paint, more of the tarmac that the police wont enforce. A cyclists only phase, with a cyclist level bicycle green, that is another matter. It would formalise that chance to get out of the way of the ASL. As for claims about traffic flow: the cyclists would be out on a green light anyway, so you can have a shorter green phase for other traffic.

The biggest change the paper calls out is designing trucks for safety: positioning the driver, mirrors, automatic sensing of cyclists, better side guards, etc. Yet this is precisely what is being postponed at the EU level. And UK cyclists can be confident that were the UK to leave the EU, better truck safety is not something a new "sovereign" government would bring out.

And mutual respect? 

The authors call out cyclists needing more experience of driving, especially to understand cornering. It may also give the riders more appreciation of how cyclists aren't that visible at night unless lit: the strength of headlights effectively darkens the rest of the street to the driver. Maybe side lights should be mandated again for that very reason.

Drivers are encouraged to recognise that cyclists do need to position themselves safely, being in the lane is not "arrogant" or "rude", it is where they need to be on many roads, especially if there is trouble ahead. Which is something the paper doesn't call out: drivers of vehicles need to be less obsessed about the bike in front and look past them to what is next, then decide whether to bother trying to overtake. Maybe that is something 20 mph zones will bring about, reduced benefits from passing, leading to increased patience. Maybe, but you still get impatient wankers and they are the ones that will kill you.

To summarise then,

This paper provides harsh detail on the actions that result in the death of people in our streets, people killed because they decided to cycle to their destination. These deaths could have been prevented.

We know that because the numbers from other countries show this. What the paper does is go into detail in London and highlight case-by-case where recorded deaths would be reduced. Which now gives ammunition to call out bollocks infra for what it is.  Anyone proposing bollocks -and here the new westminster Mall of Death proposal stands out- can be called out to show how their proposals will avoid the causes of death recorded here. Hint: ASLs don't cut it.

For the CSH proposals, it makes it a lot easier to defend the embankment plans against bollocks coming from Westminster, maybe even shite from the City of London. It's notable that the westminster plans never discussed safety at all, just said cyclists want "clear and convenient" routes. The fact that those few people who do dare to cycle across London are at risk of death doesn't show up on their radar. All they care about is their limo rides from Westminster to the City, then on to London City Airport for their weekends in Monaco with their fellow one-percenters.
