Safe Speed Forums

After Pete317 yesterday highlighted a limitation in the Ashton Mackay graph for pedestrian fatality risk, I've been looking for better data.

I'm still looking, but I've found this:

http://www1.tpgi.com.au/users/mpaine/speed.html

Contains:

"A similar relationship between initial travel speed and risk of fatality exists with cars hitting pedestrians, except that, in effect, the probability of a fatality reaches 100% at an impact speed of 60km/h (see "Vehicle Travel Speeds and the Incidence of Fatal Pedestrian Crashes" by
Anderson, McLean, Farmer, Lee and Brooks, J. Acc Anal. and Prev, Sept 1997)"

***

I note that the latest annoying "Think: slow down" TV ad makes the child fatality risk 20% at 30mph and 80% at 40mph. Where does that come from?

***

contains:

I'll continue the search. Anyone got any alternative data or (access to?) full copies of the papers cited?

- clearly the same data as above, but the x scale of one copy is wrong.

The graph is attributed to: "'European Transport Safety Council' (ETSC), http://www.etsc.be"

"The main conclusion of the Zero Vision regarding pedestrian safety is that low motor vehicle
speeds at every encounter between a motor vehicle and a pedestrian must be assured. The
maximum speed is set to 30 km/h (19 mi/h). All available empirical evidence supports the
argument strongly: an impact speed of 55 km/h (31 mi/h) in a pedestrian accident is fatal with
almost 100 percent probability; while at an impact speed of 30 km/h (19 mi/h), the risk of being
killed is reduced to less than 10 percent (Pasanen, 1992)."

This large document contains some interesting snippets:
http://www.who.int/world-health-day/200 ... apter3.pdf

Contains:
• The probability of a pedestrian being killed rises
by a factor of eight as the impact speed of the car
increases from 30 km/h to 50 km/h ( 51).

injury minimisation. In: Proceedings of the Seventh
Experimental Safety of Vehicles Conference, Paris, 5–8 June

(That's NOT the usual A&M reference, although cleary it relates to the same work)

Loads of fascinating stuff in this document:

http://www.lrrb.org/pdf/200223.pdf

On Page 11 it is declared that Pasanan bsased his work on A&M data.

Three new graphs of fatality risk by age group of pedestrian are given.

I need to see a copy of this paper:

"Vehicle Travel Speeds and the Incidence of Fatal Pedestrian Crashes" by
Anderson, McLean, Farmer, Lee and Brooks, J. Acc Anal. and Prev, Sept 1997)"

Has anyone got access / a copy?

Is this it??

Mega Link

Hell of a web address but i think it is item 11 on the list, you have to log in.
apparently free. Not got time to do it though.

Cheers

I pretty sure I have a copy on my computer at home. I'll check this evening and email it to you - if it's there.

I'm also working on something else which looks promising - I'll talk to you later.

Peter

Rats! I just paid $35.70 for it through Science direct.

Looks like crap too...

Thanks to Paddy27 for the lead...

This latest add is based on assumption, they do not have any figures to back it up.

Who determines whether a vehicle was traveling at 30 or 31 mph

It is not possible
