#safesystem — Public Fediverse posts

@RuthMalan @hibri @adrianco

Just today I listened to this amazing #MLStreetTalk with @tdietterich recommending:

» I think everybody should read #NancyLeveson book
'Engineering A Safer World'
because what she says is you don't build a #SafeSystem and then deploy it.
Safety is a really a control concept that a system is...we need to be constantly controlling and modifying the system to keep it safe.
And think it's very similar to this problem of the #UnknownUnknowns «

RT @schlthss: The #MUTCD signal warrant system - made up by a bunch of dudes in a room in the 1930s- is not an appropriate decision making tool in a #SafeSystem people first world.

RT @[email protected] The most commonly applied traffic engineering methodology says you should not put a pedestrian signal here unless there are already at least 20 pedestrians crossing. But people are never going to cross here unless there’s a signal. It’s like a traffic engineering zen koan

I really, really, really don't give a flying flip about that time you saw a bicyclist run a stop sign.

Also let's stop designing city streets like drag strips.

#RoadSafety colleagues: In my ongoing quest to reduce #crash exposure for pedestrians at 2-stage crossings (with a median/pedestrian refuge), I'm in search of examples of 2-stage #pedestrian cossings that either:

* Do not require a second request for a #WalkSignal from the #RefugeIsland (one #BegButton controls both stages), or

* Immediately trigger a ped phase when a walk signal is triggered from the refuge island.

Thanks!

Who will I get to see at #SafetySunday tomorrow? #NASEMTRB #TRBAM #RoadSafety #SafeSystem @pedbikeinfo

Again louder for those in the back: Road design determines safety. Road design determines motorist behavior. Change the road design to improve safety and change motorist behavior. #ThereAreNoAccidents #TheseAreResults
#DangerousByDesign
#SafeSystem
